Commercial Natural Gas Heaters — Industrial Heating Units

Combustion Research Corporation's commercial natural gas heaters are available from 30,000 BTU up to 220,000 BTU per unit. The Synergy series covers 30K–200K BTU for unvented applications, while the Omega II 9K series handles 30K–220K BTU in power-vented configurations, making them suitable for small service bays to large industrial warehouses.

Power-vented systems (Omega II PEP) use a blower to push combustion gases out through a vent pipe, making installation straightforward for most commercial buildings. Vacuum-fired systems (Reflect-O-Ray EDS) use an exhauster to draw combustion gases through the radiant tube, allowing longer tube runs and custom-engineered layouts covering from 500 sq ft to over 1,000,000 sq ft. Both are CSA certified and factory tested.

Not all models require direct roof venting. The Synergy series heaters operate without direct venting, reducing roof penetrations and installation costs. They can also be used in protected outdoor environments such as loading docks and covered terraces. Power-vented and vacuum-fired models do require a venting connection but offer flexible exhaust routing options.

Yes. All Combustion Research Corporation natural gas heaters carry CSA International Design Certification to ANSI/CGA Standards. Select Omega II 9K Series models also comply with ANSI Z83.20 / CSA 2.34. Every unit undergoes 100% factory testing before shipment and includes electronic flame monitoring with 100% safety lockout ignition systems.

Yes. Stainless steel variants of the Reflect-O-Ray EDS and Omega II PEP series are specifically engineered for chloramine-rich, high-humidity, and corrosive environments including natatoriums, aquatic centers, car and truck wash bays, ice arenas, chemical processing facilities, and plating shops. Stainless steel burner housings and reflectors provide long-term corrosion resistance.

Combustion Research Corporation provides a 10-year limited warranty on radiant tubes for internally created corrosion across Omega II and Reflect-O-Ray product lines. Reflect-O-Ray EDS models also include a 3-year warranty on burner controls and electrical components. The Synergy series carries a 1-year limited warranty on the complete unit. All products are 100% factory tested before shipment.

Combustion Research's radiant infrared tube heaters consistently deliver 30–50% energy savings compared to conventional forced-air heating systems. Radiant heat warms objects and occupants directly rather than heating the entire air volume of a space, reducing heat stratification and eliminating losses from air circulation. Two-stage and modulating models deliver additional efficiency by matching output to ambient temperature demand.
