Who We Serve

Heating, Ventilation and Air Conditioning (HVAC)

The evaporative cooling and thermal storage products made by BAC are used in HVAC applications around the world.

- Cooling towers and closed circuit cooling towers are used to cool the condenser water for packaged chillers.

- Evaporative condensers are used in large built-up air conditioning systems where they can offer performance advantages unmatched by water-cooled or air-cooled packaged chillers.

- BAC ice thermal storage systems are used in several new and retrofit air conditioning applications where the advantages of electrical demand shifting and low temperature cooling water can be realized.


BAC got its start in the fledgling refrigeration industry over seventy years ago with its innovative evaporative condenser line.  BAC is still the number one supplier to this market. With current concerns about phasing out CFC-based refrigerants, ammonia and hybrid refrigerant systems are increasingly popular in a wide variety of applications.

BAC evaporative condensers are used on refrigeration systems for breweries, food processing plants, cold storage warehouses, and other installations requiring evaporative condensing capability.

Light / Industrial Manufacturing

This market segment covers a wide variety of applications where cooling is needed in industrial plants, either directly in the manufacturing of a product, or indirectly in support of the manufacturing operations.

- Cooling towers and closed circuit cooling towers provide cooling for in-plant environmental control systems, jacket cooling for air compressors, metal or plastic molding machines, electric melting furnaces, machine tool cooling, etc.

- Ice thermal storage units provide economical cooling for batch or cyclical systems such as food processing, metal and plastic molding systems, steam cleaning operations, etc.

Chemical and Petroleum Processing

Virtually all chemical and petroleum processing operations require the removal of large quantities of heat, usually by means of cooling water. BAC products provide economical and environmentally sound alternatives.

- BAC factory-assembled cooling towers, closed circuit cooling towers, and evaporative condensers provide compact, economical cooling solutions for special needs: remote locations, sound-sensitive applications, etc.

Primary Metals Producers

The plants producing steel, aluminum and other primary metals, as well as the plants producing finished shapes and other by-products all need cooling water for their operations. BAC products meet their needs as shown below:

- BAC Closed Circuit Cooling Towers provide the high-quality, closed circuit cooling required for mold cooling in modern continuous casting systems.

District Cooling Plants

District cooling is a concept that has grown in popularity as commercial building owners have seen the advantages of purchasing chilled water directly from a district cooling system rather than operate their own chillers with their maintenance requirements, CFC disposal headaches, etc.

- BAC ice thermal storage systems provide demand-shifting capability and generate low temperature (36°F) cooling water, saving on first cost, installation cost and overall operating cost compared with conventional chillers and cool water storage systems.

- BAC cooling towers and evaporative condensers provide the reliable, long-life performance required by district cooling plants.

Electrical Power Generation

Most power plants using steam to generate electricity require a cooling system to condense the steam and return it to the boiler. BAC products meet that need, but we also supply solutions to other needs within the steam/electric or combined-cycle power plant.

- BAC factory-assembled cooling towers and closed circuit cooling towers are used in many auxiliary systems in the power plant, such as transformer cooling, bearing cooling, lube oil cooling, etc.
