VariMax IFRG (Indirect-Fired Recirculating Gas) combines 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.
