The GA Air Heaters are designed for cost effective heating solutions in a wide variety of applications, including greenhouses, poultry houses and other livestock structures. All models function on the principle of direct fired gas heating. Hereby a powerful fan is used to force air through a combustion chamber where the burner is situated. As the air passes through the burner, all the heat released by the combustion process is transferred to the air stream. This gives the heater a 100% thermal efficiency. The heat output of the heater can be varied by the manual adjustment of a regulating valve. The available models are GA15, GA30, GA55, GA95 and GA95t.

VariMax IFRG combines Des Champs Products heat-exchanger design with indirect heating technologies to deliver contaminant-free process air with very high efficiency. Recirculation of the combustion gases allows the heater to attain an efficiency of 90%, 1,000°F (555°C) temperature rise, 1,200°F (649°C)  discharge temperature, and a 40:1 turndown.

The VariMax™ OTH (Once-Through Heater) is a high efficiency, industrial, indirect-fired gas heater used to heat process air streams without contaminating the air with the products of combustion. The OTH is well-suited for recirculating ovens, dryers, makeup-air applications in cold environments, and industrial processes with moderate temperature rises. The counterflow configuration, four-pass design and optimized, secondary, tubular heat-exchanger result in efficiencies up to 88%.
