Kriwan Industrie-Elektronik GmbH

KRIWAN has been manufacturing protection systems for fluid machines including pumps and compressors for over 50 years. Their product portfolio centers on protection relays for pumps, pump systems, and submersible motor agitators in water and wastewater management, ranging from simple basic solutions to multifunctional premium solutions for demanding applications. The protection relays offer monitoring and protection capabilities with an internal memory that records measured values and operating data, accessible locally via the INTspector app or through integration into higher-level plant control systems. Inputs and outputs can be flexibly parameterized for the respective application. In addition to pump protection relays, KRIWAN offers a range of temperature sensors for various applications including robust PTC screw-in sensors, PTC winding sensors for motor windings, and resistance sensors with Pt100, Pt1000, or NTC for applications requiring precise temperature values. The company also provides customer-specific sensor solutions. Their products protect fluid machines from operational failures and overload across water and wastewater installations.
