Compressor heaters

With heating cable as well as silicone heater


The main purpose of these heaters is to avoid start-ups with cold oil in the crankcase and as a result increase the life time of the compressor. Elektrotermija has a standard range of heaters for compressors and crankcases, e.g. for heat pumps both in a design with heating cable, as well as silicon heaters. We can also supply tailor made solutions, with other lengths and wattages.
Compressor heater in silicone rubber withstands temperatures from -50°C to 200°C. They are supplied with a coil spring for fixing around the compressor crankcase. For better surface contact, we recommend the use of our stainless steel bundle band.
Also, Elektrotermija produces a self regulating heating cable with operating temperature 65°C, including connection cable and stainless steel bundle band for fixing around the crankcase.
