Heaters, electrical components

Constant wattage and constant resistance heating cords, self-regulating heating cables and condensate drain heaters. They are selected by power per metre and by how they are routed; we recommend the self-regulating versions wherever the heater may be covered or works in changing conditions.

PTC heaters, tubular heaters and compressor crankcase heaters. We recommend a PTC heater where self-limiting power as the temperature rises matters, and a crankcase heater wherever the oil in the compressor must not be diluted by refrigerant.

Controllers and regulators, mechanical thermostats, thermometers, hygrostats and switches for refrigeration equipment. A mechanical thermostat is enough in steady operating conditions; an electronic controller is for where temperature logging and defrost programming matter.

Power cords, ready-made harnesses for axial fans and other connection cables. The harnesses are stocked alongside the fans they fit, so drive and wiring can be sourced in a single order.
