YANMAR America Announces the Launch of the CP10WN Micro CHP Unit into U.S. Markets

There has been a recent surge in demand for energy-efficient products and greater use of domestically generated energy resources.  Micro-Cogeneration (m-CHP) systems offer higher efficiency than typical conventional electrical power generation, making them great contributors to reducing environmental impact, saving energy and cutting overall heating and electrical costs. An m-CHP unit uses a gas engine to drive a permanent magnet generator, which creates electricity using the gas. Creating electricity by using gas results in light environmental load. The exhaust heat can be used efficiently to heat a building, hot tub, swimming pool and many other applications when and where it is needed. The heat produced during generation is used to cut wasteful energy loss. As radiant heat loss is less than that of general power generation, this system greatly contributes to saving in energy and heating costs.

The engine offers a maintenance interval of 10,000 hours (or every 13.7 months) with 24/7 operation, which is one of the industry’s longest for a cogeneration gas engine.  The CP10WN CHP unit also offers 57,300 Btu/hr of recovered heat for generating hot water at temperatures of 158 degrees Fahrenheit. These units have super quiet sound levels of 54 dB(A) at 3.3 ft. and 40 dB(A) at 18 ft.

The CP10WN was built by YANMAR Energy System in Japan.  The CP10WN unit had to go through a series of steps in order to be implemented into the U.S., including tests completed by Georgia Power to ensure all power and energy requirement were met. These tests resulted in YANMAR America becoming a proud member of the EPA Combined Heat and Power Partnership.

Two m-CHP units were unveiled and tested during a ribbon cutting ceremony on December 13, 2010 at YANMAR America.  Members of the Bartow County Chamber of Commerce, Propane Education & Research Council (PERC), Georgia Power, Blossman Gas, YANMAR Energy System of Japan and YANMAR America staff were present for this event. The CP10WN cogeneration unit was revealed to the general public at the Power Gen International Show in Orlando shortly after the unveiling ceremony in Adairsville.
