Mobile HVAC & Heavy Equipment Cooling
Compact cooling for the systems that keep heavy equipment working
Construction machines, agricultural vehicles, mining equipment, and other mobile platforms carry increasingly capable electronics. Cameras, communications equipment, computing hardware, and control systems must keep operating through heat, dust, vibration, and demanding duty cycles. Packaging those systems inside protective enclosures creates another challenge: getting heat out without exposing sensitive components to the surrounding environment.
Aspen Systems develops compact vapor compression cooling solutions for OEMs integrating electronics and temperature sensitive equipment into mobile platforms. Our air cooling, liquid cooling, and custom systems help engineers manage heat where installation space and available power are limited.
Cooling applications on mobile equipment

Sealed electronics enclosures
Protecting electronics from dust, moisture, and debris often means sealing the enclosure that contains them. Aspen’s Environmental Control Units (ECUs) provide active air cooling for rugged electronics enclosures while supporting designs that keep outside contaminants away from the protected equipment. Applications can include vehicle mounted computers, communications equipment, and control electronics.

Sensors, cameras, and mission equipment
A sensor or computing payload may need its own thermal solution even when the vehicle already has cab HVAC. Aspen works with OEM teams to evaluate compact cooling for equipment mounted in space constrained locations, including systems that operate while a vehicle is moving.

Liquid cooled equipment
Some heat loads are better managed with a liquid loop or a cold plate near the component. Aspen’s Liquid Chiller Modules (LCMs) provide a starting point for equipment that needs controlled liquid cooling. Custom configurations can address the available space, electrical supply, heat rejection, and integration requirements of the platform.
Electrified and specialized vehicles
Electric and hybrid equipment can impose tight limits on power draw, packaging, and system weight. Aspen can evaluate air, liquid, or direct refrigerant approaches for a defined component cooling requirement. The right architecture depends on the heat load, required temperature, operating conditions, and vehicle design.
Built around the equipment, not just the cooling capacity
An effective mobile cooling system has to fit the entire machine. Aspen works with OEM engineering teams to define:
- Heat load and target temperature: How much heat must be removed, and under what ambient conditions?
- Electrical supply: What voltage and power are available during startup and continuous operation?
- Installation space: Where can the cooling unit, airflow path, or liquid connections fit?
- Operating environment: What shock, vibration, dust, moisture, altitude, and temperature conditions apply?
- System integration: Does the application call for conditioned air, a liquid loop, a cold plate, or a custom approach?
Aspen offers standard cooling modules as well as application specific development when an existing configuration does not meet the requirements. Its documented mobile experience includes ECUs developed for vehicle mounted military electronics and custom cooling systems tailored to vehicle applications.

Choose the cooling approach that fits your application
| Cooling approach | Consider it when… | Explore |
|---|---|---|
| Environmental Control Unit | Electronics need active air cooling inside a rugged enclosure. | Aspen ECUs |
| Liquid Chiller Module | Heat can be collected through a liquid loop and rejected away from the component. | Aspen cooling systems |
| Custom cooling system | Packaging, temperature, power, or operating conditions require a tailored design. | Custom vapor compression systems |
Aspen has supplied rugged cooling for electronics used on military vehicles, including an ECU adaptation for electronics kits on the Joint Light Tactical Vehicle. That experience gives OEMs a relevant starting point when evaluating thermal management for other mobile equipment. Each new application still requires its own engineering review and validation.

Frequently asked questions
What types of mobile and heavy equipment can Aspen Systems cooling units support?
Aspen develops compact cooling solutions for OEM applications including construction equipment, agricultural machinery, mining equipment, electric and hybrid vehicles, military vehicles, mobile communications systems, and other specialized platforms. Cooling can be configured for electronics, sensors, computing hardware, control systems, and other temperature-sensitive equipment.
How can electronics be cooled inside a sealed enclosure on heavy equipment?
Aspen Environmental Control Units (ECUs) provide active air cooling for electronics housed inside rugged or sealed enclosures. This approach allows heat to be removed while supporting equipment designs that protect sensitive electronics from dust, moisture, debris, and other environmental contaminants.
When should I use an ECU instead of a Liquid Chiller Module?
An Environmental Control Unit (ECU) is typically used when equipment requires conditioned air inside an enclosure. A Liquid Chiller Module (LCM) is better suited to applications where heat can be collected through a liquid loop or cold plate. The best approach depends on the thermal interface, heat load, target temperature, available space, power supply, and operating environment.
Can Aspen customize a cooling system for a mobile application?
Yes. When a standard ECU or Liquid Chiller Module does not meet the packaging, electrical, thermal, or environmental requirements, Aspen can evaluate an application-specific vapor-compression cooling system. Customization can address factors such as cooling capacity, form factor, voltage, airflow, coolant connections, heat rejection, and system integration.
What information does Aspen need to evaluate my cooling requirement?
Start with the heat load, target temperature, ambient temperature range, and expected operating conditions. Information about shock, vibration, dust, moisture, altitude, mounting constraints, and the preferred thermal interface is also helpful. Aspen can use these requirements to determine whether a standard cooling module or custom system is the better fit.
