Twin Fire Gas Fired Infrared Heaters

Twin Fired Infrared Heater

Roberts Gordon® Complete™ TF-Series twin fired infrared tube heater is one of the most effective unitary infrared heaters in the market today. The Complete™ TF patented twin fire infrared heater stands apart from all others. With a centralized burner location, larger surface areas can be heated with less energy. One burner box with two heat exchanger burner tubes allow for maximum heater inputs at lower clearances to combustibles, relative to similar infrared heaters. 

The standard heater design with two heaters in one reduces installation cost. Several suggested design layouts are shown below. Customization is also available with guidelines outlined in the installation, operation and service manual. Common venting or individual venting should be determined before ultimate layout for specific application is chosen.

With a range of infrared heaters available from the Roberts Gordon infrared family of products, the Complete TF supplies the highest burner inputs - up to 380,000 Btu/h.
