The Casso-Solar Technologies’ Duo-Tube TM is available with a dual coat integral gold reflective coating or an integral white refractory that directs the infrared energy to the product without the need for external reflectors.
Both the gold coating and the white refractory provide for maintenance free service.
The gold is the most efficient reflective material for all infrared energy, as it will not oxidize like most other metallic reflectors and is recommended for applications for extended heater life with heater temperatures of up to 1400 deg F.
The white refractory, slightly less efficient than the gold coating, will provide a wider emission spectrum and is suitable for extended life applications with heater temperatures of up to 1750 deg F.
Heaters are maintenance free during their lifespan.
