Infrared Heaters
Gold Unitube Heater

Gold Unitube Heater

The Casso-Solar Technologies Gold Unitube Infrared Heater contains an integral gold reflector that directs the infrared energy to the product without the need for the typical external reflector.

The integral gold reflector is maintenance free. Gold is the most efficient reflector material for all infrared energy, as it will not oxidize like other metallic reflectors.

Gold Unitubes can be mounted together to form banks; prewired into either single or multiple zones.

Supply and exhaust air systems can be provided for moisture removal or use in solvent environments.

Unitube heaters can be provided at voltages up to 600V and lengths up to 144" (3650 mm).

Watt densities up to 80 watts per lineal inch are possible, with these gold reflector infrared heaters.

If planned for vertical mounting and operation, a special coil design is utilized to prevent the heating element from slumping over time.

This is critical for maintaining even heating throughout the life of the heater.

Our team would be happy to help you in customizing these gold reflector infrared heaters to match your application requirements.
