Aspen Systems, Inc. Delivers 1,000 Environmental Control Units to the United States Special Operations Command

Marlborough, MA – September 13, 2011 – Aspen Systems announced today it has delivered the one-thousandth ECU-Chill® 550 environmental control unit (ECU) to  the U.S. Special Operations Command (USSOCOM).  The ECUs are to be used in Afghanistan for thermal management of electronic components in Mine Resistant Ambush Protected (MRAPs) vehicles.

The ECU-Chill 550 is a compact and lightweight environmental control system that maintains the internal temperature of electronics enclosures within specified conditions.  The ECU-Chill 550 protects the electronics from extreme temperature and environmental conditions of Afghanistan, keeping systems running down to -40°F (-40°C) and up to 140°F (60°C).  The ECU removes 550 Watts of heat from electronics enclosures while sealing the electronics from harmful environmental contaminants such as dust, sand and water.  The unit meets MIL-STD 810 and 461 requirements making it the ideal solution for thermal issues in the military’s austere environments.  The ECU utilizes Aspen’s miniature rotary compressor allowing the unit to be Size, Weight, and Power (SWaP) affective.

“We are proud that our ECU-Chill product is supporting the military in completing its mission in Afghanistan where our troops operate in some of the most hostile and barren environments in the world”, said Glenn Deming, Vice President of Aspen Systems.  “The ECU-Chill 550’s are mounted to keep critical electronics running while driving through rough terrain and exposed to extreme temperatures.”
