Tungsten Filaments Short Wave IR Heater Gold Coating For Solar PV Industry

Short Wave Infrared heating emitters gold coating IR bulbs for oven

No.1 Product Descriptions

Short wave halogen IR bulbs are used in various industrial applications. It contains tungsten filament, helically wound, encased in quartz envelope. Tungsten as resistive element is capable of generating temperature in excess of 2750℃. Its response time is very rapid in 1 second it emits over 90% of IR energy. It is by products free & pollution free. Heat focus is very accurate due to compact and narrow diameter of IR tubes. Short wave IR element has maximum heating rate of 200w/cm.

Benefits of Coating

1.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.

2. The emitters with coating are highly economical, converting practically all the consumed

electrical power into heat.

3.For the emitters with high watt density or the surface temperature of the tube above 800°C , we suggest to use ceramic coating as reflector because the temperature resistance is up to 1000°C .

In addition to 180°(half-tube) coating, we also manufacture 270° coating or other customer specified degrees.

No.2 Why Infrared?

Modes of heat transfer : conduction-convection-and-radiation

The principle of infrared heating - Radiation and wavelength matching

All materials including chairs,human body, everything will absorb a fraction of the infrared spectra, reflect a fraction at the surface and allow a fraction of the radiation to pass through.

The importance of wavelength matching between object and infrared emitters

Given above,we can realize the heating and drying purpose at a shorter time with less energy but get a good performance when the infrared radiation which precisely matches the absorption characteristics of the product. Depending on the temperature of the heating filament, an infrared emitter can delivers distinctly different radiation at various wavelengths. Short wave radiation can penetrate deep into some solid materials and ensure a uniform through heating.
