Thermal Management

Keep it Cool. Run it
Harder.

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.

Engineering Capabilities

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.

01

Multi-Circuit Design

Independent coolant loops for traction motors, power electronics, and hydraulic oil — designed simultaneously for optimal space utilisation and cross-circuit synergy.

02

Cooler 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).

03

Hydraulic Oil Cooling

Integrated design of water-cooled and oil-cooled circuits — hydraulic system heat rejection co-engineered with electric drivetrain cooling for hybrid machines.

04

Battery Thermal Mgmt

HV battery pack cooling system design with chiller integration, temperature uniformity analysis, and BTMS control logic for maximum cell longevity and safety.

05

Carbon 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.

06
Quiet DC Cooler

Quiet 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.

Parker QDC Series — Available via CZ Mobility
1–400 kW
Cooling Capacity Range
850 V DC
Maximum Fan Drive
12 / 24 V
Low Voltage Option
Integrated
Inverter Speed Control
2–3×
Higher power density than LDC Series.
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.
Featured Model
QDC026 FlatFit
Ultra-compact flat profile design — ideal for retrofitting electric and hybrid machines with limited hood space. Up to 850 V DC fan drive.

How We Work

From Requirements
to Running System

1

Requirements Analysis

Machine duty cycle, power levels, ambient conditions, space constraints and voltage architecture are collected and structured.

2

Thermal Simulation

Heat load calculation per circuit — motor, inverter, battery, hydraulic oil — with worst-case and continuous operating scenarios.

3

System Design

Cooler sizing, pump selection, piping layout, and Parker QDC product configuration are finalised and documented.

4

Integration & Support

Bill of materials, 3D envelope data, and commissioning support — through to full system validation on the machine.
