CZ Mobility designs complete thermal management systems for electric and hybrid off-highway machines — from engineering simulation and heat load analysis to fully integrated liquid cooling circuits. Zero emissions. Zero compromises.
Thermal Engineering,
Fully Integrated
CZ Mobility brings a carbon-zero engineering philosophy to every project — designing thermal systems that don't just cool machines, but enable them to perform at their full electric potential.
Heat Load Simulation
Duty-cycle based thermal analysis for electric motors, inverters, and batteries. We calculate precise heat rejection requirements across all operating modes before hardware is selected.
01Multi-Circuit Design
Independent coolant loops for traction motors, power electronics, and hydraulic oil — designed simultaneously for optimal space utilisation and cross-circuit synergy.
02Cooler Sizing & Selection
Engineering calculations for Parker QDC air-fluid coolers matched to your application's ambient temperature, altitude, duty cycle, and voltage architecture (12V–850V DC).
03Hydraulic Oil Cooling
Integrated design of water-cooled and oil-cooled circuits — hydraulic system heat rejection co-engineered with electric drivetrain cooling for hybrid machines.
04Battery Thermal Mgmt
HV battery pack cooling system design with chiller integration, temperature uniformity analysis, and BTMS control logic for maximum cell longevity and safety.
05Carbon Zero Framework
Every system is evaluated for total energy efficiency — fan power, pump losses, and thermal recovery. We target minimum auxiliary energy consumption alongside cooling performance.
06Quiet DC Cooler
QDC Series
Parker's QDC air fluid cooler series is purpose-built for the electrification market — combining high voltage fan drive, intelligent speed control, and industry-leading power density in a robust off-highway package.
The integrated inverter controls fan rotation speed efficiently, minimising power consumption while ensuring quiet operation for noise-sensitive environments.
Strengths & Highlights
- Quiet fan and fan motor — optimised blade geometry and brushless motor technology for low-noise environments and emission-sensitive worksites.
- High power density — 2 to 3 times greater than the LDC series, enabling smaller installation footprint on compact machines.
- Efficient and robust design — extends operating lifetime, reduces service intervals and total maintenance costs over the machine's life.
- Low pressure drop matrix — high cooling capacity cooler core with minimal hydraulic resistance for pump energy savings.
- Easy to maintain and retrofit — designed for accessibility and compatibility across a wide range of existing machine platforms.
Applications
From urban hydrogen buses to mining excavators — CZ Mobility thermal solutions are engineered for the full spectrum of electric and hybrid mobile machines.
