SRF type heating cables are semiconductor, self-regulating oval cross-section heaters. Their main feature is the ability to self-regulate, ie automatically reduce their own heating power with increasing temperature (PTC characteristics). Additional advantages are: the possibility of their own crossing and overlapping without the risk of overheating and burnout, and the possibility of cutting to the required length.
The lengths of these heaters strongly depend on the unit power of the heater (10, 16, 24, 30 or 40 W/m) and range from 0.5 m to 200 m (for 230 V voltage standards), and depend on the application and needs of a heated facility. For specific information about this type of heater, related to solving one of your electric heating problems don’t hesitate to send us an inquiry!
