69 - series. New KRIWAN compressor protection

INT69 YF - consistently developing active compressor protection

The KRIWAN range of compressor protection devices continues to grow. The latest addition are devices that are fully suitable for use with frequency converter equipment. KRIWAN protection enables the monitoring of motor voltages for single-phasing or faulty rotary fields even for motors controlled by frequency converters, in the 20 – 100 Hz range.

In the near future, the new generation of protective devices may be converted to enable direct monitoring for rotary field imbalance. This allows for timely hazard detection. The motor is shut down before a malfunction occurs.

Hence, KRIWAN protection technology will contribute to a further reduction of the motor burnout rate in the future.
