BorgWarner supplies the electric auxiliary thermal coolant pump (ATCP) for a turbocharged compact SUV built by a major Chinese automaker. Featuring a brushless, no-leak, low-noise design with integrated microcontroller, BorgWarner's ATCP provides a continuous flow of coolant through auxiliary circuits even when the engine is shut down, helping auxiliary components maintain optimal operating temperature and contributing to longer component life, improved fuel economy and lower emissions. In this application, a 100-watt ATCP assists in turbocharger and indirect charge air cooling.

BorgWarner's family of ATCPs is designed for a variety of automotive and commercial vehicle voltage ranges to support a wide range of small- and medium-flow applications. When the engine is running, an integrated microcontroller communicates directly with the engine controller to maintain optimum speed for engine conditions, from 0 to 100% depending on the application. When the engine is off, the ATCP transmits heat to a heater core (or heat exchanger) to keep auxiliary systems working at optimal temperatures.

Featuring an optimized brushless DC motor and floating rotor, BorgWarner's ATCP delivers superior performance with very low noise. The innovative no-leak design does not require a face or lip seal, eliminating a high-wear component for improved durability.
