Infrared Radiant-Mounted Gas-Fired Heating Systems

Radiant tube heaters are classified as gas-fired infrared heating devices and rank among the group of decentralized heating systems. As opposed to central heating systems, they are characterized by the fact that their heat is generated in the exact location it’s needed, versus passively throughout the space and provides redundancy in that if a single tube heater fails in a facility many others are still operating.

The Variable Gas Volume Infrared Radiant Tube Heater is a premium Radiant Tube Heater engineered to deliver superior heating performance in large industrial and commercial spaces. Designed with advanced infrared radiant heating technology, this high-efficiency heater uses gas fuel to emit infrared radiation directly onto floors, objects, and work zones, ensuring faster heat-up times, improved thermal comfort, and lower operating costs compared to conventional convective heating systems.

About Radiant Tube Heaters

The Infrared Radiant Tube Heater adopts a tubular design that distributes infrared heat evenly across expansive floor areas — ideal for high ceilings, warehouses, workshops, distribution centers, manufacturing facilities, and other large-scale spaces requiring targeted and efficient heating. Infrared radiant heating warms people and objects directly rather than relying on warming large volumes of air, resulting in reduced heat loss and decreased energy consumption. 

Unlike traditional forced-air units, this radiant tube heater reduces thermal stratification in high-ceiling environments, meaning heat stays where it is needed most at the ground level, enhancing comfort and productivity.

Technical Advantages of Radiant Tube Heating

Direct Radiant Heat Transfer: Infrared radiant heating warms surfaces and occupants directly, enhancing heat comfort even at lower air temperatures and reducing fuel costs. 

Reduced Air Movement & Clean Heat: Radiant heaters do not depend on circulating air, which minimizes dust, airborne particles, and heat loss due to convection. 

Zoned Heating Capability: Multiple radiant tube heaters can be configured to provide zoned heating, delivering warmth precisely where needed while avoiding unnecessary heating of unoccupied zones. 

Lower Maintenance: With fewer moving parts and reduced dependency on blower fans or ducts, this radiant tube heater lowers maintenance requirements and long-term operating costs.

Inside the tube heater, the combustion of the gas-air mixture takes place within a long steel tube, producing a ~1012 °F (~580 °C) heat and subsequently emitting infrared radiation. The surrounding surfaces absorb this thermal energy and, in turn, re-emit it into the environment, creating a balanced micro-climate. The concept is seen in nature, too: the sun’s rays pass through the air without heating it and emit their energy when they fall on surfaces.

Infrared gas radiant heaters are a popular form of heating because the heating takes place where it is required and is, therefore, less wasteful. This reduces energy costs significantly and improves people’s comfort.
