How it Works

Infrared halogen heaters use quartz heat lamps to produce shortwave energy.  This energy is usually directed at the required target area by a precision designed parabolic reflector.  Shortwave energy moves in straight lines from the reflector to the target area without heating the air in between.  However once the energy is absorbed by solid bodies, which could be objects or people, it is experienced as heat.

Shortwave energy cannot be blown off course by breezes and draughts and is ideally suited as a heating method in intermittently used buildings and for spot heating within a larger unheated space.

A brief explanation of a halogen lamp

To produce shortwave energy a very high temperature is required.  This is achieved by centering a tungsten filament in a quartz tube.  The tungsten filament operates at a very high temperature and without the presence of a halogen gas; particles from the filament would evaporate from the filament and be deposited on the relatively cooler inner wall of the tube causing blackening and severely reducing lamp life. 

The presence of a halogen gas gives rise to a phenomenon known as the halogen cycle.  A chemical reaction between the halogen gas, tungsten and oxygen creates tungsten oxyhalide molecules which, in a vapour form, migrate from the inner wall of the tube back towards the filament where the high temperature breaks the tungsten oxyhalide molecules apart.  At this stage the tungsten atoms are re-deposited on the filament whist the oxygen and halogen atoms move back towards the wall of the lamp allowing the cycle to repeat.

The halogen cycle allows a lamp to operate at high temperatures without blackening for several thousand hours.
