High efficiency is achieved by circulating the products of combustion from the primary heat exchanger through a secondary heat exchanger of special corrosion-resistant alloy. The heater is equipped with a horizontal standard fitting for connection to a condensate drain. Model SHE is manufactured at an ISO 9001 registered facility. Model TR tubular radiant heaters are available in sizes 50,000 through 200,000 BTUH input. Lengths are from 20 to 70 feet in straight or optional U or L configuration.
Heaters operate on inside or outside combustion air.
Reznor Model RIH high-intensity infrared heating equipment warms people, heats floors, walls, machinery and other surfaces without heating the air between.
