All of our emitters can be coated with a layer of gold or ceramic as reflectors. The gold/ ceramic coating can concentrate the heat, increasing the effectiveness of the heat output.
The emitters with coating are highly economical, converting practically all the consumed electrical power into heat.
For the emitters with high watt density or the surface temperature of the tube above 800¢XC , we suggest to use ceramic coating as reflector because the temperature resistance is up to 1000¢XC .
In addition to 180¢X (half-tube) coating, we also manufacture 270¢X coating or other customer specified degrees.
