KPU

The KPU Thermostats are temperature controlled electrical switches, which are applied for regulation and safety monitoring of refrigeration and air conditioning systems. KPU sensors are available with vapor charge or with adsorption charge. The Thermostats with adsorption charge are widely used to give frost protection, while vapor charged sensors are used where small differential is required. All KPU Thermostats have a single pole double throw (SPDT) contact system. The position of the switch depends on the thermostat setting and the bulb temperature.
