Infrared Gas Fired Heaters


With over 2.2 billion square feet of conditioned floor space Cambridge understands what is required to heat and ventilate commercial and industrial facilities. Our approach to heating large open spaces starts with our HTHV products. But, we recognize that not all buildings are the same. There are those unique circumstances, based on a buildings design, where our HTHV products cannot distribute warm air to a small section of a building. It is in these areas that we recommend pairing infrared tube heaters to supplement the energy efficient HTHV units that are heating the majority of the space. Infrared heaters should only be used as a secondary heat source for spot and zone heating small occupied spaces within a larger facility. When combined, Cambridge infrared radiant heaters and direct-fired S-Series HTHV heaters can be a cost-effective building heating solution for those more difficult applications.

All ITH-Series low intensity infrared heaters include a high-efficiency reflector to maximize the amount of radiant energy that reaches the floor. Cambridge ITH-Series infrared radiant heaters include a high-performance burner with self-diagnostic ignition and integral post purge feature for increased reliability. 



  • The industry’s most efficient reflector to maximize the amount of radiant energy that reaches the floor
  • Flexible heater placement provides focused heat where it is most needed.
