KP pressure controls are designed to protect refrigeration systems from excessively high discharge pressures, excessively low suction pressures, to start/stop compressors or to operate fans of aircooled condensers. KP temperature controls with adsorption charge are the optimum choice for frost protection of chillers. The enhanced contact system for 16 A makes it possible to operate electrical motors up to 2 kW directly, without the use of contactors.
