Parker air fluid cooler for limited-space electrification

Parker Hannifin has launched its QDC026 FlatFit air fluid cooler specifically for modern vehicles and compact machinery where installation space is at a premium.

The QDC026 FlatFit has an installation depth of just 290 mm – reducible to 250 mm upon request. It delivers two to three times higher cooling capacity at the required water-glycol flow rate compared to the QDC 12/24 V DC series, the company said, making it suited for inverter and motor cooling systems. Alternatively, it can achieve the same cooling capacity with a significantly reduced installation footprint.

A key feature of the new air fluid cooler is its 850V DC brushless motor with integrated inverter, which precisely controls fan rotation speed via a standard CAN bus signal. This intelligent speed regulation is designed to minimize power consumption by adjusting the fan to the minimum required rpm to effectively dissipate heat from the fluid.

The cooling solution is fully harmonized with Parker’s IQAN controller and sensorics, enabling smooth integration into existing vehicle control systems, Parker noted. An optional cleaning and flushing feature allows fluid purity down to 5 µS/cm, supporting long-term maintenance and optimal performance.

Additional features include integrated ports for sensorics and bleeding, a fan drive mounted on a swivel frame for easy cleaning and IP68 protection for durability and resilience in harsh operating environments.
