Solutions for your application. Reliable protection and advanced condition monitoring for efficient running.

Protection relays

For over 50 years, KRIWAN has been your specialist for the electronic protection of refrigerant compressors and rotating machines. Our INT69 motor protection and tripping device has become synonymous with the KRIWAN brand for good reason.

Product overview

Oil level regulator

KRIWAN oil level regulators ensure that systems run like a well-oiled machine, as the oil level is not only reliably measured, but also topped up if necessary. At the same time, important data is collected and evaluated in order to detect irregularities in the processes quickly and reliably.

Product overview

Oil differential pressure switches

Differential pressure switches from KRIWAN combine reliable protection with extremely easy handling, making them the perfect solution for monitoring oil pumps and refrigerant compressors. They can be used as a stand-alone solution or as a component of a comprehensive control system.

Product overview

Level switches

Our level monitoring switches can be used to reliably monitor the levels of a wide range of liquids. KRIWAN relies on a two-part protection concept: on the one hand, the level is monitored by an optical screw-in part, and on the other, the evaluation electronics ensure that you can keep an eye on even the smallest changes.

Product overview

Temperature sensors

Our temperature sensors are specially designed for KRIWAN protection systems. The response points of the PTC and PT100/PT-1000 sensors can be precisely reproduced and therefore provide reliable results, even with minimal temperature fluctuations. This is guaranteed by our strict factory standards and regular testing in our in-house test center.

Product overview

Wind sensors

In the field of wind sensors, KRIWAN offers solutions for almost every application - from industrial to meteorological, from simple to extremely demanding. The robust and reliable KRIWAN wind direction sensors deliver optimum results in almost every field of application. Of course, this also applies to the KRIWAN anemometers. These reliably record the current wind speed and convert it into a linear output signal.

Product overview

Air flow sensors

Whether filter system, fan, electric heater or inlet and outlet system: wherever air is moved, KRIWAN air flow sensors reliably monitor and register the smallest deviations. And with maximum flexibility, as the measurements are independent of direction, with adjustable start-up bridging.

Product overview

Gateways and equipment

KRIWAN not only offers reliable sensors and protective devices, as a system provider we also ensure the best connections. KRIWAN Bluetooth and USB gateways enable access to the diagnostic devices of KRIWAN devices via DP interface. This means that measurement data can be easily evaluated and used for process optimization as well as for the early detection of malfunctions. At the same time, KRIWAN devices can also be parameterized via the gateways.
