The Parker QDC air fluid cooler series offers a unique cooling solution for the electrified, mobile market.
Among the series' most outstanding features are:
• High power density. The QDC offers 2-3x higher power density than the LDC series.
• High efficiency. Integrated inverter controls the rotation speed with a standard PWM signal to reduce the power consumption to the minimum required RPM to disipate the power out of the fluid.
• High noise reduction. The high efficient design of the Parker heat exchanger turbulator together with the rotation speed control ensures quiet operation, suitable for operation even in noise emission reduced areas.

This series can be fitted optionally with an IQAN controller, smart 24V DC water-glycole pump, and a tank system. The maximum cooling capacity is 26 kW at 40°C, difference in temperature between ambient and cooler inlet, size 017.

Markets:
• Mobile, electrified

Features/Benefits:
• Quiet fan and fan motor
• High power density
• Efficient and robust design which extends operating lifetime and reduces service and maintenance costs
• Cooler matrix with low pressure drop and high cooling capacity
• Easy to maintain and easy to retrofit in many applications

The correct working temperature produces a number of economic and environmental benefits:
• The precise control of the cooling capacity extends the service life of the electric motor and the drive.
• Service and repair costs are reduce
• High efficiency level maintained in continuous operation – the system’s efficiency falls if the temperature exceeds the ideal working temperature.

Applications:
• Truck cranes
• Body builders
• Mining machinery
• Forestry machines
• Refuse trucks
• Sweepers
• Lawn mowers
• Mini- and Medium sized excavator
• Surface drilling systems
• Hydrogen power fuel cell stack cooling

We have only included cooler part numbers up to size 17. Larger cooler sizes are also available on request, up to 140 kW at 40°C, difference in temperature between ambient and cooler inlet. Please contact Parker.
