Complete Infrared Tube Heating 

Roberts Gordon® Complete™ CTH2D-Series infrared tube heater has a reputation. Roberts Gordon unitary infrared heaters have been around for over 40 years and continue to be the preferred infrared supplier. With many older heaters still in operation today, it has been proven that quality, premium products provide reliable, long-lasting equipment and performance. Additionally, setting Roberts Gordon® apart from all others, a three year limited warranty is included with this and every Roberts Gordon infrared tube heater. 

Standard heater design includes direct spark ignition and standard safety features. Inside the heater burner box, electrical components are partitioned from burner components resulting in longer life of individual components. LED diagnostics allow for ease of maintenance during heater troubleshooting.
