Filtration Products Business

Air Filtration and Particulate Collection Systems. Federal and state legislation and related regulations and enforcement have increased the demand for air filtration and particulate collection systems by requiring industry to meet primary and secondary ambient air quality standards for specific pollutants, including particulate. In certain manufacturing applications, particulate collection systems are an integral part of the production process. Examples of such applications include the production of cement, carbon black and industrial absorbents.

The principal types of industrial air filtration and particulate collection systems in use today are baghouses, cartridge collectors, electrostatic precipitators, scrubbers and mechanical collectors. This equipment is used to eliminate particulate from the air by passing particulate laden gases through fabric filters (filter bags) or pleated media filter elements, in the case of baghouses or cartridge collectors, and between electrically charged collector plates, in the case of electrostatic precipitators.

Products and Services. The Company manufactures and sells a wide variety of filter elements for cartridge collectors and baghouse air filtration and particulate collection systems. The Company manufactures filter elements in standard industry sizes, shapes and filtration media and to custom specifications, maintaining manufacturing standards for more than 10,000 styles of filter elements to suit substantially all industrial applications. Filter elements are manufactured from industrial yarn, fabric and papers purchased in bulk.   Most filter elements are produced from cellulose, acrylic, fiberglass, polyester, aramid or polypropylene fibers.

 The Company also manufactures filter elements from more specialized materials, sometimes using special finishes.

The Company markets numerous filter-related products and accessories used during the installation, operation and maintenance of cartridge collectors and baghouses, including wire cages used to support filter bags, spring assemblies for proper tensioning of filter bags and clamps and hanger assemblies for attaching filter elements. In addition, the Company markets other hardware items used in the operation and maintenance of cartridge collectors and baghouses. The Company also provides maintenance services, consisting primarily of air filtration system inspection and filter element replacement, using a network of independent contractors. The sale of filter-related products and accessories, collector inspection, maintenance services and leak detection account for approximately 11% of the net sales of the Company's filtration products and services.

Over the past three years, the Company's Filtration Products Business has served more than 4,000 user locations. The Company has particular expertise in supplying filter bags for use with electric arc furnaces in the steel industry. The Company believes its production capacity and quality control procedures make it a leading supplier of filter bags to large users in the electric power industry. Orders from that industry tend to be substantial in size, but are usually at lower margins than other industries. In the fiscal year ended January 31, 2006, no customer accounted for 10% or more of net sales of the Company's filtration products and services.

Marketing. The customer base for the Company's filtration products and services is industrially and geographically diverse. These products and services are used primarily by operators of utility and industrial coal-fired boilers, incinerators and cogeneration plants and by producers of metals, cement, chemicals and other industrial products.

The Company has an integrated sales program for its Filtration Products Business, which consists of field-based sales personnel, manufacturers' representatives, a telemarketing operation and computer-based customer information systems containing data on nearly 18,000 user locations. These systems enable the Company's sales force to access customer information classified by industry, equipment type, operational data and the Company's quotation and sales history. The Company believes the computer-based information systems are instrumental in increasing sales of filter-related products and accessories and maintenance services, as well as sales of filter elements. The Company’s filtration products are marketed domestically under the names, Midwesco Filter and TDC Manufacturing.

The Company markets its U.S. manufactured filtration products internationally using domestically based sales resources to target major users in foreign countries. Export sales, which were approximately 10% of the domestic filtration company’s product sales during the year ended January 31, 2006, were slightly higher than the previous year. Nordic Air Filtration A/S (“Nordic Air”), a wholly-owned subsidiary of the Company, manufactures in Nakskov, Denmark, and markets pleated filter elements throughout Europe and Asia, primarily to original equipment manufacturers.

Trademarks. The Company owns the following trademarks covering its filtration products: Seamless Tube®, Leak Seeker®, Prekote®, We Take the Dust Out of Industry®, Pleatkeeper®, Pleat Plus® and EFC®.

Backlog. As of January 31, 2006, the dollar amount of backlog (uncompleted firm orders) for filtration products was $20,426,000. As of January 31, 2005, the amount of backlog was $17,518,000. Certain customers have placed orders that are deliverable over multiple years. Therefore, approximately $5,552,000 of the backlog as of January 31, 2006 is not expected to be completed in 2006.

Raw Materials and Manufacturing. The basic raw materials used in the manufacture of the Company's filtration products are industrial fibers and media supplied by leading producers of such materials. The majority of raw materials purchased are woven fiberglass fabric, yarns for manufacturing Seamless Tube® products and other woven, felted, spun bond and cellulose media. Only a limited number of suppliers are available for some of these materials. From time to time, any of these materials could be in short supply, adversely affecting the Company's business. The Company believes that supplies of all materials are adequate to meet current demand. The Company's inventory includes substantial quantities of various types of media because lead times from

2

suppliers are frequently longer than the delivery times required by customers. Nevertheless, the Company employs an aggressive program to limit inventory to levels compatible with meeting customer needs.

Competition. The Filtration Products Business is highly competitive. In addition, new installations of cartridge collectors and baghouses are subject to competition from alternative technologies. The Company believes that, based on domestic sales, its principal competitors in this segment are: the BHA brand within GE Energy Services; the Menardi division of Beacon Industrial Group; W.L. Gore & Associates, Inc. Donaldson Company, Inc.; Farr Company; and Clarcor, Inc. There are at least 50 smaller competitors, most of which are doing business on a regional or local basis. In Europe, several companies supply filtration products, and the Company is a relatively small participant in that market. Some of the Company's competitors have greater financial resources than the Company.

The Company believes quality, service, and price are the most important competitive factors in its Filtration Products Business. Often, a manufacturer has a competitive advantage when its products have performed successfully for a particular customer in the past. Additional effort is required by a competitor to market products to such a customer. In certain applications, the Company's proprietary Seamless Tube® product and customer support provide the Company with a competitive advantage. Certain competitors of the Company may have a competitive advantage with respect to their own proprietary products and processes, such as specialized fabrics and fabric finishes. In addition, some competitors may have cost advantages with respect to certain products as a result of lower wage rates and/or greater vertical integration.

Government Regulation . The Company's Filtration Products Business is substantially dependent upon governmental regulation of air pollution at the federal and state levels. Federal clean air legislation requires compliance with national primary and secondary ambient air quality standards for specific pollutants, including particulate. The states are primarily responsible for implementing these standards and, in some cases, have adopted more stringent standards than those issued by the U.S. Environmental Protection Agency (“U.S. EPA”) under the Clean Air Act Amendments of 1990 ("Clean Air Act Amendments”).

Piping Systems Business

Products and Services. The Company engineers, designs, manufactures and sells specialty piping systems and leak detection and location systems. The Company's specialty piping systems include (i)industrial and secondary containment piping systems for transporting chemicals, hazardous fluids and petroleum products, (ii) insulated and jacketed district heating and cooling piping systems for efficient energy distribution to multiple locations from central energy plants, and (iii) oil and gas gathering flow lines and long lines for oil and mineral transportation. The Company's leak detection and location systems are sold as part of many of its piping systems, and on a stand-alone basis, to monitor areas where fluid intrusion may contaminate the environment, endanger personal safety, cause a fire hazard, impair essential services or damage equipment or property.

The Company's industrial and secondary containment piping systems, manufactured in a wide variety of piping materials, are generally used for the handling of chemicals, hazardous liquids and petroleum products. Industrial piping systems often feature special materials, heat tracing, leak detection and special fabrication. Secondary containment piping systems consist of service pipes housed within outer containment pipes, which are designed to contain any leaks from the service pipes. Each system is designed to provide economical and efficient secondary containment protection that will meet all governmental environmental regulations.

With respect to the leak detection and location system capabilities, the Company believes that its systems are superior to systems manufactured by other companies. The Company's leak detection and location systems are being used to monitor fueling systems at airports, including those located in Denver, Colorado; Atlanta, Georgia; and Frankfurt and Hamburg, Germany. They are also used in facilities used for mission-critical operations such as those operated by web hosts, application service providers, internet service providers, and in many clean rooms, including such facilities operated by IBM, Intel and Motorola. The Company believes that, in the United States, it is the only major supplier of the above-referenced types of specialty piping systems that manufactures its own leak detection and location systems.

3

The Company's piping systems are frequently custom-fabricated to job site dimensions and/or incorporate provisions for thermal expansion due to varying temperatures. This custom fabrication helps to minimize the amount of field labor required by the installation contractor. Most of the Company's piping systems are produced for underground installations and, therefore, require trenching, which is done by unaffiliated installation contractors. Generally, sales of the Company's piping systems tend to be lower during the winter months, due to weather constraints over much of the northern hemisphere. In the fiscal year ended January 31, 2006, no single customer accounted for more than 10% of the net sales of the Company's piping systems.

Marketing. The customer base for the Company's piping systems products is industrially and geographically diverse. The Company employs a national sales manager and regional sales managers who use and assist a network of approximately 80 independent manufacturers' representatives, none of whom sells products that are competitive with the Company's piping systems.

Recent Development. In March 2006, the Company opened a new facility (PPME), in the United Arab Emirates (“U.A.E.”). PPME will manufacture specialty pre-insulated piping systems. Initially, the plant will produce pipe that will serve the district cooling market in the U.A.E. as well as other Middle Eastern countries such as Kuwait, Qatar, and Oman. District cooling is the main air conditioning method in the Middle East. With major construction going on in Dubai and other Middle East locations, cooling needs for these buildings is expected to increase greatly. The cooling load in the Middle East is expected to grow by 4 million tons in the next 6 years, according to the International District Energy Association. PPME also intends to participate in the oil and gas markets in the region including hot oil, sulfur and liquid natural gas.

In September, 2005 the Company received initial orders for its new “Autotherm™”, automatically applied Glass Syntactic Polyurethane (GSPU) for oil and gas sub-sea flowlines. The Company’s Autotherm™ GSPU is a thermal insulation application process that continuously molds specially formulated compounds on the exterior of steel pipes for oil and gas flowlines to be installed on the sea floor connecting oil wells to their host platforms. The Autotherm™ system is designed to provide reliable insulation properties when subjected to the large hydrostatic pressures of deep water over long periods of time. These pipelines will be installed in water depths ranging from 2,000 to 4,500 feet. Insulating sub-sea oil flowlines is a common practice at these water depths in order to prevent paraffin or hydrate build-up on the internal pipe surfaces thus ensuring a steady flow of oil.

Patents, Trademarks and Approvals. The Company owns several patents covering the features of its piping and electronic leak detection systems, which expire commencing in 2006. In addition, the Company's leak detection system is listed by Underwriters Laboratories and the U.S. EPA and is approved by Factory Mutual and the Federal Communications Commission. The Company is also approved as a supplier of underground district heating systems under the federal government guide specifications for such systems. The Company owns numerous trademarks connected with its piping systems business. In addition to Perma-Pipe®, the Company owns other trademarks for its piping and leak detection systems including the following: Chil-Gard®, Double-Pipe®, Double-Quik®, Escon-A®, Ferro-Shield®, FluidWatch®, Galva-Gard®, Hi Gard®, Poly-Therm®, Pal-AT®, Ric-Wil®, Ric-Wil Dual Gard®, Stereo-Heat®, Safe-T-Gard®, Therm-O-Seal®, Uniline®, LiquidWatch®, TankWatch®, PalCom®, Xtru-therm®, Ultra-Pipe®, PEX-GARD®, and ULTRA-THERM®. The Company also owns United Kingdom trademarks for Poly-Therm®, Perma-Pipe® and Ric-Wil®, and a Canadian trademark for Ric-Wil®.

Backlog. As of January 31, 2006, the dollar amount of backlog (uncompleted firm orders) for piping and leak detection systems was $19,869,000, substantially all of which is expected to be completed in 2006. As of January 31, 2005, the amount of backlog was $18,125,000.

Raw Materials and Manufacturing. The basic raw materials used in the production of the Company's piping systems products are pipes and tubes made of carbon steel, alloy and plastics and various chemicals such as polyols, isocyanate, polyester resin, polyethylene and fiberglass, mostly purchased in bulk quantities. The Company believes that there are currently adequate supplies or sources of availability of the needed raw materials. However, there are risks and uncertainties with respect to the supply of certain of these raw materials that could impact their availability in sufficient quantities to meet the Company’s needs.

The sensor cables used in the Company's leak detection and location systems are manufactured to the Company's specifications by companies regularly engaged in the business of manufacturing such cables. The Company owns patents for some of the features of its sensor cables. The Company assembles the monitoring component of the leak detection and location system from standard components purchased from many sources. The Company's proprietary software is installed in the system on a read-only memory chip.

The Company's manufacturing processes for its piping systems include equipment and techniques to fabricate piping systems from a wide variety of materials, including carbon steel, alloy and copper piping, and engineered thermoplastics and fiberglass-reinforced polyesters and epoxies. The Company uses computer-controlled machinery for electric plasma metal cutting, filament winding, pipe coating, insulation foam and protective jacket application, pipe bending, pipe cutting and pipe welding. The Company employs skilled workers for carbon steel and alloy welding to various code requirements. The Company is authorized to apply the American Society of Mechanical Engineers code symbol stamps for unfired pressure vessels and pressure piping. The Company's inventory includes bulk resins, chemicals and various types of pipe, tube, insulation, pipe fittings and other components used in its products. The Company maintains a quality assurance program involving lead worker sign-off of each piece at each workstation, statistical process control, and nondestructive testing protocols.

Competition. The piping system products business is highly competitive. The Company believes its principal competition in this segment consists of Rovanco Piping Systems, Inc.; Thermacor Process, Inc.; Asahi/America; GF Plastics Systems; Bredero-Price, a subsidiary of Shaw Industries, Inc.; CRP of UK; Soctherm of Italy; Soccoreal of Argentina; Logstor Rohr of Denmark; TraceTek; Raychem, a Division of Tyco Thermal Controls LLC, a subsidiary of Tyco Industries; RLE Technologies; Tracer Technologies; Arizona Instrument Corp.; Veeder Root; and Pneumecator.

The Company believes that quality, service, a comprehensive product line and price are the key competitive factors in the Company's Piping Systems Business. The Company believes it has a more comprehensive line of piping systems products than any of its competitors. Certain competitors of the Company have cost advantages as a result of manufacturing a limited range of products. Some of the Company's competitors have greater financial resources than the Company.

Government Regulation. The demand for the Company's leak detection and location systems and secondary containment piping systems is driven by federal and state environmental regulation with respect to hazardous waste. The Federal Resource Conservation and Recovery Act requires, in some cases, that the storage, handling and transportation of certain fluids through underground pipelines feature secondary containment and leak detection. The National Emission Standard for Hydrocarbon Airborne Particulates requires reduction of airborne volatile organic compounds and fugitive emissions. Under this regulation, many major refineries are required to recover fugitive vapors and dispose of the recovered material in a process sewer system, which then becomes a hazardous secondary waste system that must be contained. Although there can be no assurances as to the ultimate effects of these governmental regulations, the Company believes they may increase the demand for its piping systems products.

Industrial Process Cooling Equipment Business

Products and Services. The Company engineers, designs, manufactures and sells coolers for industrial purposes. The Company's cooling products include: chillers (portable and central); cooling towers; plant circulating assemblies; hot water, hot oil, and negative pressure temperature controllers; water treatment equipment; specialty cooling devices for printing presses and ink management; and replacement parts and various accessories relating to the foregoing products. The Company's cooling products are used to optimize manufacturing productivity by quickly removing heat from manufacturing processes. The Company combines chillers and/or cooling towers with plant circulating systems to create plant-wide systems that account for a large portion of its business. The Company specializes in customizing cooling systems and their computerized controls according to customer specifications.

5

The principal markets for the Company’s cooling products are thermoplastics processing and the printing industries. The Company also sells its products to original equipment manufacturers, to other cooling manufacturers on a private branded basis and to manufacturers in the laser, metallizing, and machine tool industries.

The Company believes it manufactures the most complete line of chillers available in its primary markets. It incorporates a microprocessor capable of computer communications to standard industry protocols. While portable chillers are considered to be a commodity product by many customers, the Company believes that its units enable it to provide the customer with quality, features, customization and other benefits at a competitive price. The Company believes that the ability to offer central chillers that are used for plant-wide cooling provides it with a unique, total cooling approach concept sales advantage.

Marketing. In general, the Company sells its cooling products in the domestic and international thermoplastics and printing markets as well as to manufacturers of digital video discs (“DVDs”) and other non-plastics industries that require specialized heat transfer equipment. Domestic thermoplastics processors are the largest market served by the Company, representing the core of its business.

There are approximately 8,000 companies processing plastic products in the United States, primarily using injection molding, extrusion, and blow molding machinery. The Company believes the total U.S. market for water cooling equipment in the plastics industry is $100 million annually, and that the Company is one of the three largest suppliers of such equipment to the plastics industry. The Company believes that the plastics industry is a mature industry with growth generally consistent with that of the national economy. Due to the high plastics content in many major consumer items, such as cars and appliances, this industry experiences cyclical economic activity. The Company believes that it is recognized in the domestic plastics market as a quality equipment manufacturer and that it will be able to maintain current market share, with potential to increase its market share through product development. The Company's cooling products are sold through independent manufacturers' representatives on an exclusive-territory basis. Twenty representatives are responsible for covering the United States and are supported by four regional managers employed by the Company.

Sales of the Company's cooling products outside the United States have mainly been in Latin America. Some international sales have been obtained elsewhere as a result of the assembly of complete worldwide PET (plastic bottle) plants by multinational companies. The Company believes that it has a significant opportunity for growth due to the high quality of its equipment and the fact that it offers complete system design. Many United States competitors do not provide equipment outside the U.S. and, while European competitors sell equipment in Latin America, the Company believes that they lack system design capabilities and have a significant freight disadvantage. The Company markets its cooling products through a combination of manufacturers' representatives, distributors and consultants managed by regional managers, reporting to a National Sales and Marketing Manager.

The Company has increased sales to non-plastics industries that require specialized heat transfer equipment, usually sold to end users as a package by the supplier of the primary equipment, particularly in the laser industry, metallizing industry, and machine tool industry. The Company believes that the size of this market is more than $200 million annually. The original equipment manufacturer generally distributes products to the end user in these markets.

Trademarks. The Company has registered the trademarks Thermal Care®, AWS® and Applied Web Systems®.

Backlog. As of January 31, 2006, the dollar amount of backlog (uncompleted firm orders) for industrial process cooling equipment was $9,306,000, substantially all of which is expected to be completed in 2006. As of January 31, 2005, the amount of backlog was $5,321,000.

Raw Materials and Manufacturing. The Company uses prefabricated sheet metal and subassemblies manufactured by both Thermal Care and outside vendors for temperature controller fabrication. The production line is self-contained to reduce handling required to assemble, wire, test, and crate the units for shipment.

Cooling towers up to 120 tons in capacity are assembled to finished goods inventory, which allows the Company to meet quick delivery requirements. The cooling towers are manufactured using fiberglass and hardware components purchased from several sources. The wet deck is cut from bulk fill material and installed inside the tower. Customer-specified options can be added at any time. The Company believes that its access to sheet metal, subassemblies, fiberglass and hardware components is adequate.

The Company assembles all plant circulating systems by fabricating the steel to meet the size requirements and adding purchased components to meet customers’ specifications. Portable chillers are assembled utilizing components both manufactured by the Company and supplied by outside vendors. Central chillers are manufactured to customer specifications.

Competition. The Company believes that there are about 15 competitors selling cooling equipment in the domestic plastics market. The Company further believes that three manufacturers, including the Company, account for approximately 50% of the domestic plastics cooling equipment market. Many international customers, with relatively small cooling needs, are able to purchase small refrigeration units (portable chillers) that are manufactured in their respective local markets at prices below that which the Company can offer due to issues such as freight cost and customs duties. However, such local manufacturers often lack the technology and products needed for plant-wide cooling systems. The Company believes that its reputation for producing quality plant-wide cooling products results in a significant portion of the Company’s business in this area.

The Company believes that quality, service, a comprehensive product line and price are the key competitive factors in its Industrial Process Cooling Equipment Business. The Company believes that it has a more comprehensive line of cooling products than any of its competitors. Certain competitors of the Company have cost advantages as a result of manufacturing in non-union shops and offering a limited range of products. Some of the Company's competitors may have greater financial resources than the Company.

Government Regulation. The Company does not expect compliance with federal, state and local provisions regulating the discharge of materials into the environment or otherwise relating to the protection of the environment to have a material effect on capital expenditures, earnings or the Company’s competitive position. Management is not aware of the need for any material capital expenditures for environmental control facilities for the foreseeable future. Regulations, promulgated under the Federal Clean Air Act, prohibit the manufacture and sale of certain refrigerants. The Company does not use these refrigerants in its products. The Company expects that suitable refrigerants conforming to federal, state and local laws and regulations will continue to be available to the Company, although no assurances can be given as to the ultimate effect of the Federal Clean Air Act and related laws on the Company.

Employees

As of March 31, 2006, the Company had 760 full-time employees, 83 of whom were engaged in sales and marketing, 215 of whom were engaged in management, engineering and administration, and 462 were engaged in production. Hourly production employees of the Company's Filtration Products Business in Winchester, Virginia are covered by a collective bargaining agreement with the International United Automobile, Aerospace & Agricultural Implement Workers of America, which expires in October 2006. Most of the production employees of the Company's Industrial Process Cooling Equipment Business are represented by two unions, the United Association of Journeymen and Apprentices of the Plumbing and Pipefitting Industry of the United States (UAJAPPI) and the International Brotherhood of Electrical Workers Union (IBEW). The collective bargaining agreement for UAJAPPI is scheduled to expire on June 1, 2006, and the IBEW agreement expires on May 31, 2006, with both agreements thereafter continuing to be in effect for yearly periods unless amended or terminated in writing.

Competition Business. The businesses in which the Company is engaged are highly competitive. Many of the competitors are larger than the Company and have more resources. Many of the Company’s products are also subject to competition from alternative technologies and alternative products. To the extent the Company relies upon a single source for key components of several of its products, the Company believes that there are alternate sources available for such components; however, there can be no assurance that the interruption of supplies of such components would not have an adverse effect on the financial condition of the Company, and that the Company, if required to do so, would be able to negotiate agreements with alternative sources on acceptable terms.

Government Regulation. The demand for the Company’s leak detection and location systems and secondary containment piping systems is driven primarily by government regulation with respect to hazardous waste. Laws such as the Federal Resource Conservation and Recovery Act (“RCRA”), and standards such as the National Emission Standard for Hydrocarbon Airborne Particulates (“NESHAP”), have increased the demand for the Company’s leak detection and location and secondary containment piping systems. The Company’s filtration products business to a large extent is dependent on governmental regulation of air pollution at the federal and state levels. The Company believes that continuing growth in the sale of filtration products and

9

services will be materially dependent on continuing enforcement of environmental laws such as the Federal Clean Air Act Amendments of 1990 (“Clean Air Act Amendments”). Although changes in such environmental regulations could significantly alter the demand for the Company’s products and services, the Company does not believe that such a change is likely to decrease demand in the foreseeable future. In addition, the Company has experienced, and may experience additional, increased costs of compliance with other government regulation, such as the Sarbanes-Oxley Act.

Dividends. The Company has not paid dividends in the past and does not anticipate paying cash dividends on its common stock in the foreseeable future. The Company’s line of credit agreement contains certain restrictions on payment of dividends.

Changes in Government Policies and Laws, Worldwide Economic Conditions . The Company anticipates that international sales will represent an increasing portion of its total sales and that continued growth and profitability may require further international expansion. The Company’s financial results could be affected by changes in trade, monetary and fiscal policies, laws and regulations, or other activities of U.S. and non-U.S. governments, agencies and similar organizations. These conditions include but are not limited to changes in a country’s or region’s economic or political conditions, trade regulations affecting production, pricing and marketing of products, local labor conditions and regulations, reduced protection of intellectual property rights in some countries, changes in the regulatory or legal environment, restrictions on currency exchange activities, burdensome taxes and tariffs and other trade barriers. International risks and uncertainties, including changing social and economic conditions as well as terrorism, political hostilities and war, could lead to reduced international sales and reduced profitability associated with such sales.

Economic Factors . The Company is exposed to fluctuations in currency exchange rates and commodity prices. The Company monitors and manages currency exposures that are associated with monetary asset positions, committed currency purchases and sales, and other assets and liabilities created in the normal course of business. Failure to successfully manage these risks could have an adverse impact on the Company’s financial position, results of operations and cash flows.

Seasonality. Sales in the Piping Systems business segment have a tendency to be lower during the winter months due to weather constraints in the northern hemisphere. Severity and duration of winter weather could have an adverse effect on the results of this segment.
