Compact Liquid Chiller Modules (LCMs)
Aspen developed a series of small liquid chiller modules that provide the core cooling system (compressor, condenser, expansion valve, evaporator) that is ready to connect to a cooling fluid circuit or be customized to meet specific requirements.
The miniature LCMs are used in a wide variety of industries including defense/aerospace, electronics, medical, laboratory, life science, photonics/lasers, and semiconductor.
The New, G-Series LCMs are Eco-friendly, low GWP versions of the original LCMs. Designed to meet all future EPA and EU environmental standards.

Environmental Control Units (ECU)
Ruggedized, Military-Grade AC and HVAC Systems
The ECU Series of Environmental Control Units are ruggedized air conditioning systems for cooling electronics in austere and mobile applications. They maintain sealed electronics enclosures at or below ambient temperatures, enabling Commercial-Off-The-Shelf (COTS) electronics to be safely and effectively used for computing and communications in extremely hot or cold environments. These systems have been fully ruggedized for military use to MIL-STD-810. The ECU Series continuously maintains a temperature of ≤125°F (51.6°C) inside an electronics enclosure in a 125°F ambient environment removing 550 Watts of heat. The electronics remain sealed against all environmental contamination, improving reliability
