Further advantages of the ADAPT EXTENDED level switches
The ADAPT EXTENDED level monitor is specially designed for demanding thermal environments and is ideal for heat pumps and industrial refrigeration systems that reach temperatures of up to 160°C. This is particularly important in applications with high-temperature refrigerants or in processes that require reliable monitoring under extreme conditions. Thanks to its robust design, the sensor remains precise and durable even at high temperatures.
The sensors are specially developed for applications that require high or low temperatures. They are resistant to icing at temperatures below 0 °C and can withstand media temperatures of up to +160 °C, making them ideal for use in demanding environments.
A major advantage of KRIWAN level sensors is their modular design. The screw-in part of the sensor can remain permanently in the system, while the electronic part can be easily replaced without draining or shutting down the entire system. This significantly reduces downtimes and simplifies maintenance work, as no expensive downtimes or specialised personnel are required to bleed the system.
Thanks to their precise sensor technology, the ADAPT EXTENDED models can be used in a wide range of applications, including CO₂ refrigerant collectors, oil separators, compressors and heat pumps. They are compatible with natural refrigerants such as CO₂ and NH₃ and offer reliable monitoring even under difficult conditions.
The sensors are mechanically robust and can withstand vibrations and high loads. This makes them ideal for use in industrial and moving systems, such as compressors or heat pumps.

Areas of application
Wide range of applications for the level monitor ADAPT EXTENDED
The level switches ADAPT EXTENDED from KRIWAN offer reliable monitoring of liquid levels in refrigeration systems and heat pumps that are exposed to extreme temperatures. With their high resistance to icing and temperature stability, they ensure the stable operation of low- or high-temperature systems.
Suitable for applications with high temperatures and demanding environments.
In the process industry, applications are often exposed to extreme temperatures and demanding environments. The new sensor variant is specially developed for such conditions and ensures precise monitoring of liquid levels, even at high temperatures. This helps to increase process reliability and avoid production downtime, which in turn leads to greater efficiency throughout the production chain.
Monitoring of liquid levels in compressors, pumps and tanks.
Monitoring fluid levels in compressors, pumps and tanks is crucial in HVAC/R systems to ensure efficient cooling and heating. The new sensor variant offers reliable performance even at high temperatures, which is crucial for operational safety, especially in complex HVAC/R systems. This means that faults can be recognised at an early stage and unplanned maintenance work can be avoided.
Ensuring operational continuity in cooling and heating systems.
In the food industry, operational continuity in cooling and heating systems is crucial for the quality and safety of products. The new sensor variant supports the seamless monitoring of liquid levels, preventing temperature fluctuations and maintaining the required standards in food production. This minimises the risk of product loss and maximises system availability.
