Quiet Air Fluid Coolers
The Parker QDC (Quiet Air Fluid Cooler with DC motor) series offers a unique cooling solution for the electrified, mobile market.
Electrification remains one of the primary trends in the global mobile machine market as vehicle makers push hard to introduce cleaner technologies that result in lower emissions. Manufacturers have come to realise the need for much lower emissions and environmental friendly technologies. 

The ability to meet legal requirements for zero emissions, the ability to work outside of normal business hours due to their quiet operation, the ability to have a fast-charging option to work longer hours — these benefits of electrified vehicles open the doors of possibility for those looking to expand their business down the road.
Thermal management covers all cooling and heating tasks in an electrified mobile working machine or an electrified commercial vehicle. Almost all the technical conditions are changing in terms of the temperature ranges, heating/cooling power, the number of heating/cooling tasks and the fluids used. The variety of coolants ranges from water glycol to special electrically non-conductive fluids and demineralised water (DI-water), which is used in particular for the cooling of fuel cells.
Complementary to all Parker products for electrification
The QDC cooler range, whether 24 VDC or 600 VDC ties in perfectly with other Parker product lines suitable for electrified applications.
The combination of Parker products  ensures greatest efficiency:
scalable motors - aligned motor controls - versatile electro-hydraulic work functions
Using Parker components reduces complexity.
Our products are coordinated in such a way that they minimize additional parts, thus diminishing leak points and extra pipework.
Using Parker components drives the efficiency of your electrified application.
