The tungsten filament used in these heaters is the porcupine or star type coil, which can be operated at temperatures up to 1500°C (2732°F), with peak wavelength emissions of approximately 1.6 microns. It reaches top temperatures within seconds.
As well as having excellent structural rigidity, this coil is designed to minimize light output and maximize IR emission thereby increasing IR radiant efficiency.
Standard Products: 240 v, R7s termination and 10 mm diameter glass.
Note : For heaters besides above diameter please contact us.

SHORT WAVE QUARTZ TUNGSTEN HEATERS
These heaters are filled with halogen gas to allow the supported tungsten filament to reach temperatures as high as 2600°C (4712°F).
With peak wavelength emissions of approximately 1 micron, they are extremely penetrative and allow rapid on/off cycles.
Standard Products: R7s termination and 10 mm diameter glass.
Note : For heaters besides above diameter please contact us.
