Air conditioning and refrigeration technology
Climate change and population growth are increasing the need for cooling throughout the world: food, medicines, lab samples must remain cool, as well as in the case of production halls and offices to maintain the productivity of people and machines. The demand for energy efficiency and supply reliability is also increasing. Failures in refrigeration plants are often the result of overheating of the motor, too little lubrication on sliding surfaces and bearings, or of fluctuations in the power supply.
The KRIWAN product portfolio for refrigeration systems enables reliable and comprehensive protection of your system. The data interfaces of the KRIWAN devices allow data to be easily read out and integrated into the higher-level system control.

The DELTA-P differential pressure switches offer a reliable and effective solution for monitoring the oil pressure in semi-hermetic reciprocating refrigerant compressors. Thanks to their simple installation, high reliability and numerous advantages, they contribute significantly to the safety and longevity of refrigeration systems. The implementation of such monitoring systems is therefore not only a recommended but a necessary measure for the operation of modern refrigeration systems

Differential pressure switches play an essential role in various technical applications as they can measure the finest pressure differences. Their functional principle is based on pressure measurement between two points and they are used in areas such as industrial process monitoring, the automotive industry and medical technology. Their versatility is demonstrated in the monitoring of air flows, filters and fluids.
KRIWAN has been a competent partner for air conditioning and refrigeration technology for over 50 years. We protect and monitor your compressors and enable reliable and efficient system operation. We offer more than just individual components - with the KRIWAN system solution, consisting of our different devices, the gateways and the INTspector app, you receive all protection and monitoring components from a single source.
Easy to implement, flexible and scalable.
With the Diagnose protection system, KRIWAN enables the basic function of safety shut-down and enhances communication
through diagnostic modules. That way, the real condition of the machine can be seen and predictive maintenance undertaken. The KRIWAN Diagnose system can be freely configured and completely networked via integrated interfaces. Today, principles such as permanent condition monitoring and predictive
maintenance through diagnostics and communication are integral parts of the machine protection system.
To provide the right solution for condition monitoring with and for our customers, we develop modules that combine protection and regulation, as well as set up the diagnostic software accordingly. KRIWAN protection controls are designed for other markets, not only for the refrigeration and air conditioning sector.
