Modine Invited to Demonstrate HMMWV with Alternative CO2 HVAC System at Department of Defense Reception.

RACINE, Wis. -- Modine Manufacturing Company (NYSE:MOD), a $1.2 billion company specializing in research and development in heating and cooling technology, announced today it will demonstrate its new alternative HVAC system on an Up-Armored M1114 High Mobility Multi-purpose Wheeled Vehicle (HMMWV) at an invitation only reception for the Deputy Under Secretary of Defense on November 30, 2004.

The reception in Arlington, Virginia will celebrate the kickoff of fiscal year 2004 continuing projects and 2005 new start project for the Comparative Testing Programs. "For Modine it gives us a chance to show our technology to the Comparative Testing Office (CTO) in conjunction with the Defense Acquisition Challenge Program (DACP) of the Department of Defense. Attendees will see the HMMWV in the parking area and be able to discuss the system components with another Modine representative. Using CO2 refrigerant system allows it to cool the M1114 HMMWV faster than today's R134a package and goes a long way to "Cool-The-Force" when they operate in a hot environment," said Sam Collier, Modine's Advanced Systems Development Manager.

Modine announced earlier this month it has been awarded a nearly $3 million contract with the United States Army, Research, Development and Engineering Command, to optimize the design of the HMMWV cooling system. The first generation contract, awarded in September 2003 for $1.35 million, allowed Modine to develop climate control systems and outfit the first CO2 cooled HMMWV and Environment Control Units (ECU) used to provide space heating and cooling for equipment and personnel.

These alternative HVAC systems utilize transcritical carbon dioxide (CO2) technology, which provides a number of advantages over the current R134a refrigerant. CO2 is a "natural" refrigerant that is pulled from the air and if leaked, poses no threat to the environment. It also releases no harmful hydro-fluorocarbon (HFC) gases. It is non-toxic and non-flammable and enjoys the highest safety rating established by commercial standards.

Modine has been working on CO2 HVAC technology for eight years. "With impending legislation in Europe that proposes to start phasing out R134a for automotive AC systems in 2011, Modine has successfully developed and demonstrated full systems integration capability on a number of vehicle platforms," said Steve Memory, Modine's Manager of Global HVAC Technology. "The contract with the U.S. Army has greatly helped this development work and proved that Modine's system has the durability to operate very well under extremely challenging conditions."

Modine, with fiscal 2004 revenues of $1.2 billion, employs more than 8,500 people worldwide at 35 facilities, and specializes in thermal management components, bringing heating and cooling technology to diversified markets. Modine's products are used in light, medium, and heavy-duty vehicles, HVAC equipment, industrial equipment, refrigeration systems, fuel cells and electronics.
