As more vehicles are manufactured to operate or fueled with CNG (Compressed Natural Gas) and LNG (Liquid Natural Gas), federal code mandate a low emitter temperature on gas fired infrared tube heaters of 750 F for heaters installed in these facilities.  The code is NFPA10A - Code for Motor Fuel Dispensing Facilities and Repair Garages.

. The NFPA30A "...where major repairs are conducted on CNG or LNG fueled vehicles, open flame heaters or heating equipment with surfaces having a temperature in excess of 750oF shall not be permitted"

Space Ray's CNG PTS/ U series heaters comply with these national codes and offers a solution with our CNG PTS/ U series heater in both straight & U-shaped configurations in 40, 50, 60, & 75,000 Btu capacities.
