Tecumseh Products Co., Ann Arbor, Mich., has launched its Green Technology initiative by committing resources to design, develop, manufacture and market compressors and condensing units optimized for use with low Global Warming Potential refrigerants.

The company also is a signatory to The Natural Voice, a global call for action supported by industry and research that points to the environmental, economic and social potential of natural refrigerants in heating, cooling and refrigeration.

According to Tecumseh, it is focused on developing compressors utilizing hydrocarbon refrigerants R290 (propane) and R600a (isobutane), which have ozone-depletion potential factors of zero - a notable improvement over the global warming potential of the refrigerants they are intended to replace.
