RACINE, Wis. - Modine Manufacturing Co. has been recognized for its work on developing alternative carbon dioxide HVAC systems for the U.S. Army.

The company has worked on creating this type of system for the armored M1114 high-mobility, multipurpose, wheeled vehicle. The project team developing the system has won the U.S. Army's Environmental Excellence in Weapons Acquisition Award, and has been nominated for the Office of the Secretary of Defense's Environmental Award.

Modine and the U.S. Army have worked for the past three years to develop an environmentally friendly HVAC system using carbon dioxide for the vehicle.

"I'm extremely proud to be associated with such a fine team as the one Modine has assembled for the prototype HMMVV development effort," said John Manzione, special projects officer for the environmental systems branch of the U.S. Army's Communications-Electronics Research Development and Engineering Center. "We think it will lead to great improvements in the way the army cools its tactical vehicle systems."

"This is quite an honor. The system we developed with the army produces lower amounts of greenhouse gasses than the existing R-134A system, so it's better for the environment. It's the same size as the current system, but 8 percent lighter in weight and 30 percent smaller in volume," said Steve Memory, Modine manager of global HVAC technology.

Modine has been awarded several army contracts to develop and optimize the design of climate-control systems.
