Space heaters are used to heat small confined spaces. Space heaters are used widely in industries in panels and in electric machines such as alternators and motors to prevent condensate formation on the winding.
The space heaters should be switched as soon as the alternator or the motor comes to a stop.
Space heaters enable localised heating of an area to a specific degree. Space heaters for industrial application are electric heaters. Space heaters work on the principle of convection or radiation.
Convective heaters work by first heating the air which transfers the heat to the surrounding area. Radiative heaters work by emitting infrared radiation which heats the surface on which it falls. Infrared heaters work faster and can be used to heat a specific location.
