During engine idle or part load operating conditions, fuel injected into the combustion cycle may not be sufficient to maintain gas temperatures. Generating engine back pressure is a method for increasing engine out temperature. Back pressure can be achieved by utilising a valve after the turbocharger.

The electric water pump powered by a motor pumps cooling water to the engine to keep it at an optimal temperature.

For hybrid vehicles, its EHRS are widely used to reduce engine warm-up times to improve fuel economy, reduce emissions and provide cabin heating. 

The compact integration of controller, motor, and pump enables application on various vehicles.

Optimized control of motor lowers the noise.

Product is available from 30W to 80W (input).

Flow is shut at engine start in order to quickly warm-up the engine.

Valve is designed to open by the force of cooling water flow so that the valve could stay open during power off (for fail safe).
