Infrared Radiant Tube Heaters

With proper installation and maintenance, radiant tube heaters commonly last 15-20 years or more. Combustion Research Corporation backs its radiant tubes with a 10-year warranty against internally created corrosion, plus 3-year warranties on burner controls, reflecting the rugged aluminized or stainless steel construction used throughout the product line.

These systems operate on natural gas, propane (LP), or oil, depending on the model. Oil-fired versions like the Reflect-O-Ray OIL EDS are designed for off-grid or rural facilities without natural gas access, while natural gas and propane models cover most standard commercial and industrial installations.

Vacuum-fired systems use an exhauster to draw combustion gases through the tube run and out a single vent stack, ideal for large custom-engineered layouts up to 1,000,000+ sqft. Power-vented units are self-contained, factory-assembled packages with their own blower, suited to simpler installations requiring less field engineering.

Models range from 30,000 Btu/hr up to 250,000 Btu/hr per unit, with straight or U-tube configurations. Dual-input modulating models provide a high-fire and low-fire setting (roughly 30% lower), allowing systems to match heat output to variable load conditions across aircraft hangars, warehouses, and production floors.

Yes. Stainless steel burner housing and reflector options are purpose-built for chloramine, humidity, and road-salt exposure found in natatoriums, ice arenas, and vehicle wash bays. These variants resist corrosion far better than standard powder-coated units in chemically aggressive or high-moisture facilities.

Vacuum-fired systems route multiple heater tubes to a single exhauster and vent stack, minimizing roof penetrations. Power-vented units vent individually through a sidewall or roof cap with their own integral blower. Your representative can help determine the best venting approach for your building layout.
