Wet Surface Air Cooled (WSAC) systems are optimized for industrial applications where rugged design/fabrication and cost effective, water efficient closed-loop cooling/condensing are required. WSAC heat exchangers have clear advantages in many applications involving liquid cooling or vapor condensing. WSAC systems have been successfully utilized in industries such as power, steel, refining, chemical & petrochemical processing, and food/beverage.

Niagara's 'No-Frost' refrigeration and dehumidification products are used in very diverse commercial and industrial applications ranging from blast freezers to breweries to cosmetic production. The unique characteristics of these products are energy efficient frost-free refrigeration, dew point depression, and air cleaning with airborne pathogen removal.


Founded in 1904, Niagara Blower Company was originally known for its success in manufacturing high quality air conditioning and heating equipment for industrial applications.  In 1914, Niagara worked to design and perform contract ventilating and dust collecting installations in Western New York and Pennsylvania.  Moving into the late 1920s, the potential for equipment in the air conditioning and refrigeration field was recognized. At this time the vertical spray type air conditioning unit was developed and patented, replacing many of the air-washer type units.

By 1930, Niagara Blower Company was manufacturing and marketing air engineering products and systems including air conditioners, fan heaters, fan coolers, and central systems for air conditioning, humidifying, de-humidifying, processing, drying, and dehydrating.

As time passed, the field of endeavor broadened and other lines of equipment were added such as the Niagara Aero-Pass Condenser, Niagara Oilout, Niagara Aero Heat Exchangers including Aero Aftercoolers and Vapor Condensers, dehumidification with the Hygrol Conditioner and Concentrator, 'No-Frost' Spray Cooler and Concentrator, and the Air Handling Unit.

Since the early 1950s, Niagara has earned a reputation for its successful development of innovative, well engineered designs for varied heat transfer applications.

Today, Niagara Blower Heat Transfer Solutions is concentrated in three distinct product lines. Each of these product lines offer unique and cost effective solutions to the varied, and highly specialized, cooling needs in industry.

Niagara product lines include WSAC closed-loop, evaporative liquid coolers and vapor condensers;  “No-Frost” refrigeration and dehumidification systems; and Kathabar dehumidification and energy recovery systems.
