Our Gas Infrared Radiant Tube Heaters Services

CRC manufactures gas infrared radiant systems for high-bay, industrial, commercial, agricultural, and specialized facility heating.

Reflect-O-Ray

Custom-engineered negative-pressure radiant tube systems for large commercial and industrial buildings, with 40,000-250,000 BTU inputs and coverage from small zones to massive facilities.

Omega II

Unitary power-vented gas infrared tube heaters for commercial and industrial zones, available in straight or U configurations with 105K-200K BTU inputs.

Serengeti-IR

Compact 40K-60K BTU gas-fired radiant tube heaters for smaller commercial, agricultural, detail-bay, single-bay, and light-industrial heating applications.

Warehouse Heating

Radiant infrared systems for high-bay warehouses and distribution centers, helping reduce heat loss from dock doors and warm occupied floor-level areas.

Hangar Heating

Gas-fired radiant tube heating for hangars with 20-foot-plus ceilings and large aircraft doors, engineered for fast recovery after door cycles.

Manufacturing Heat

Infrared heating solutions for production floors, work cells, fabrication areas, and industrial plants where exhaust loads and high ceilings challenge forced-air systems.

Engineered Comfort

Targeted Heat for Demanding Facilities

Gas infrared radiant tube heaters are designed for facilities where heating air alone is inefficient. CRC systems place radiant energy at the occupied level, helping workers, vehicles, floors, and equipment stay warm even in high-bay spaces. With vacuum-vented, power-vented, compact, stainless, natural gas, and propane options, each application can be matched to performance, durability, and operating-cost goals.

Built for Demanding Facilities

Specified across demanding commercial, industrial, agricultural, and specialty facilities throughout North America.

"Our 16-bay garage runs with doors opening constantly, so keeping students comfortable through Connecticut winters was a real challenge. Reflect-O-Ray units installed over each bay solved it. The concrete floor acts as a heat sink, absorbing and re-radiating warmth back into the space, so students feel warm at lower thermostat..."

Ella T. Grasso Technical School

"We chose a two-stage Omega II 30-ft low intensity tube system for our new two-story hospital, and it's been the right call. The 60,000–100,000 MBH output keeps our rear operating area genuinely comfortable, not just warm air blowing around. Our concrete slab absorbs and re-radiates the heat, so the space..."

Fenton River Veterinary Hospital

"Hangars are the hardest buildings to heat. High bay, minimal insulation, and a massive overhead door that dumps cold air in every time it opens. Forced air simply couldn't keep up without burning through energy. Ten 40-foot straight tubes at 150 MBH with reflectors changed that completely. Radiant heat warms..."

Tac Air – Bradley International Airport

"Heating a 120-yard indoor field under a 65-foot domed roof is not a standard job, and Reflect-O-Ray was the only system engineers felt could be tailored to it. Twelve 360,000 B/H burners firing 140-foot tubes condition the entire space efficiently. Infrared fit directly into our campus energy conservation standards and..."

Frequently Asked Questions

How do gas infrared radiant tube heaters work?

Gas infrared radiant tube heaters burn natural gas or propane to heat an emitter tube, which radiates energy toward floors, equipment, inventory, and people. Instead of heating the full air volume first, radiant energy warms occupied surfaces directly. This is especially effective in high-bay or door-cycling buildings where warm air from forced-air systems rises or escapes quickly.
