KP and KPI Series: The KP series is the industry standard for refrigeration and air conditioning. These switches are optimized for gaseous media and are often used to start or stop compressors and fans. The KPI variant is more robust, designed for light industrial applications involving both liquids and gases (like water pumps or oil lines).
RT Series: Built for heavy-duty industrial and marine applications, the RT series features a larger enclosure and is ideal for environments where high reliability and durability are paramount, such as boiler safety or marine engine rooms.
MP Series: These are specialized differential pressure switches used primarily to monitor oil pressure in refrigeration compressors, ensuring the machine doesn't run without proper lubrication.
