Superior Radiant Products says its SRP Modulus™ adaptive modulating infrared tube heater provides thermal efficiencies in excess of 80%. Rates range from 80,000 to 200,000 Btuh with a 40% modulating differential. A built?in “Quick?Start” function ramps up to high power resulting in optimum temperatures achieved almost as soon as the heater is turned on. Lengths run from 20 ft to 60 ft, NG or LPG.
