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%.
The heater uses a Maxon® industrial gas burner for clean, reliable combustion. The OTH can handle airflows from 2000 to 65,000 SCFM, produce air temperature rises from 20°F to 150°F, with a maximum outlet temperature of 600°F, and are constructed of heavy-duty, stainless-steel for strength, durability and corrosion-resistance.
