GORDONRAY® DF Dual-Fired Infrared Heater - (Two-Stage Operation)

The GORDONRAY® DF features two-stage technology that can effectively adjust to sudden high heat-loss conditions, or economically maintain steady comfort levels due to the ability to fire at two distinct rates. Built to the same high standards that are expected with a ROBERTS GORDON® infrared heater, the GORDONRAY® DF is an excellent fuel efficient choice for heating in commercial/industrial applications.
The GORDONRAY® DF has a number of features that include dual burner status indicator lights, convenient external thermostat connection points that can also power a low voltage thermostat, a hinged door for easy access to electrical components during annual maintenance and fall season start-up. Maximize the radiant output by adding our new high efficiency aluminum reflectors to increase comfort levels and fuel savings.
Like our other unitary heaters, the GORDONRAY® DF has flexible layout options that include straight, u-tube, or “L” configurations along with a broad range of burner sizes and tube lengths.

Gas-fired low-intensity infrared tube heaters are an extremely efficient and high comfort heating solution. Low-intensity tube heaters provide more design flexibility than any other type of infrared heater with the ability to direct heat only where needed in spot heating applications. Or designed to heat and maintain high comfort levels for an entire space, including buildings with high ceilings.
Gas-fired low intensity infrared tube heaters are ideal for applications such as: loading docks (dock doors), auto/vehicle repair shops, warehouses, distribution centers, manufacturing, airplane hangars, high heat-loss areas, greenhouses (e.g. flowers, cannabis, etc...), firehouses, outdoor patios (hospitality), chicken houses, hog houses, horse barns, military, and more!
