Enclosure heaters are energy efficient
31 May 2012
Rittal enclosure heaters provide a high level of energy efficiency thanks to the use of self-regulating positive temperature coefficient (PTC) technology. The heaters provide superior heating performance whilst maintaining the physical dimensions of previous models. Fitting is either by snap-fastening to 35mm support rails or direct screw-fixing on a mounting plate. Assembly is completed using clamp-type wiring terminals.
Precise temperature control is achieved via a thermostat in the supply to the heater. Alternatively, where low air temperatures inside the enclosure are to be avoided to prevent the formation of condensation, control may be effected by connecting a hygrostat in the same manner. Both a thermostat and hygrostat can be integrated so that the heater is controlled on both temperature and relative humidity.
With thermal outputs in the range of 10W to 800W, either a single enclosure heater or multiple units, can maintain a warm and dry environment for electrical equipment, whatever the size of enclosure.
