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"

Gas Fired Products  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.

Unsurpassed Corrosion Resistance: 

The aluminized steel tubing is heat treated up to 1400°F where
the aluminum coating (supplied by aluminized steel) is fused into the tubing. The heat
treating process forms a homogenous layer of iron-aluminum (Fe-Al), which is
extremely oxidization resistant.

Higher Operating Temperatures:

This protective coating of the homogeneous alloy (Fe-Al) can withstand higher
operating temperatures than other conventional tube materials (as certified by Armco
Research and Technology Laboratories). The maximum operating emitter tube
temperature is 1250°F.

Higher Surface Emissivity:

An additional benefit of the heat treating process is a greatly enhanced external surface
emissivity as well as improved internal surface absorptivity.
