Further advantages of the level switches ADAPT
The level switch ADAPT 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.
A major advantage of KRIWAN level switches 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.
The level switch ADAPT is designed to meet the current and future requirements of the refrigeration industry. It is fully compatible with the latest refrigerants, including those with lower GWP (Global Warming Potential), which are required to comply with stricter environmental regulations. This makes it a future-proof solution for operators who want to make their systems sustainable and save costs in the long term.
Perfectly suited for demanding applications in the HVAC/R industry and beyond!
Level switches ADAPT for your refrigeration system
The KRIWAN level switches ADAPT were developed for large compound and refrigeration systems, as well as for large unit manufacturers. They are suitable for use on heat pumps and impress with their consistent quality, made in Germany.
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.

These are often already installed on the compressor. However, KRIWAN level switches can also be used on pressure vessels such as oil receivers, refrigerant receivers or oil separators. We have screw-in parts certified in accordance with the Pressure Equipment Directive in our portfolio for this purpose.
Refrigerant, oil, fruit juice, etc.
No, you do not need different versions of the level switch. You can monitor refrigerant and oil with the same product.
