The PTS/PTU Series low-intensity infrared tube heaters are available in natural and propane gas and use positive pressure to push combustion products through the heavy-duty calorized aluminumized or alumatherm-steel combustion chamber. These series, with more than 80 different configurations and in capacities from 40,000 to 200,000 Btu/hr, offer optimum flexibility in custom designing an infrared heating system.


The PTS series is available in multiple configurations (straight, L, Z, and expanded U-shape) with lengths from 10- to 70-feet long. For added versatility, 90° elbows, corner reflectors, and side reflectors are available for close area mounting near walls, doors, and corners.



The PTU series is available in seven different configurations and provides more uniform radiant heat energy distribution. The PTU series is ideal for high heat loss areas and spot heating. Space-Ray, Charlotte, N.C.
