Enclosure Heaters

Enclosure Heaters

Seifert fan heaters have a small and compact design, they heat up dynamically and are very quiet in operation. The internal warm air is equally distributed throughout the control cabinet. An additional advantage of fan heaters compared to PTC heaters is a much lower starting current. PTC heaters are compact in size, have a wide voltage range and the heating power adjusts in relation to the ambient temperature, resulting in better efficiency. KH 801 heater series come standard with a built-in thermostat.
