IMW Industries Secures Long-Term Agreement from UTC Power  To Provide Key Fuel Cell Modules on Exclusive Basis

Chilliwack BC, Canada (October 5, 2011) — IMW Industries announced today that it has signed a long-term agreement with UTC Power, a unit of United Technologies Corp., to be the exclusive provider of natural gas reforming and CSA cooling modules for its PureCell® Model 400 stationary fuel cell production. No contract value was disclosed for the agreement, which lasts through the end of 2014.

“We have worked with UTC Power to provide best-in-class natural gas processing technology for its stationary fuel cells and are pleased to be chosen as sole supplier for its market-leading system,” said Brad Miller, president and CEO of IMW. “This agreement complements our growth in the expanding market for natural gas compression equipment for fueling transportation in North America and worldwide.”

The PureCell solution from UTC Power uses fuel cell technology to generate 400 kW of electric power using natural gas as input fuel. In a fuel cell, no fossil fuel combustion takes place. The only byproduct is heat that can be easily harnessed to provide space heating or domestic hot water, or with the addition of an optional absorption chiller, can produce cooling. More than half of the energy potential in traditional, centralized power generation goes up the stack as exhaust heat. UTC Power fuel cell systems convert heat exhaust into cooling and heating, turning potential waste into useable energy. While central powerplants achieve energy conversion percentages in the mid-30-percent range, the PureCell system can attain energy conversion efficiencies as high as 90 percent.
