VariMax IFRG is used to heat process airstreams without contaminating the air with the products of combustion. The ultra-high-efficiency heater is particularly useful for spray dryers and industrial processes with high temperature rises. The counterflow heat exchanger with hot-side recirculation results in efficiencies greater than 90 percent. The energy savings result in a short payback. Standard features include stainless steel heat exchanger, FM- or IRI-certified gas trains and complete heater controls. It is custom designed for each application with 1,000°F (555°C) max temperature rises and exit temperatures up to 1,200°F (649°C).
