Tecumseh Provides Updated Position on Refrigerant Transition
Company suggests suitable replacements for R-404A and R-134a
In follow-up to a document that Tecumseh issued in October 2014 regarding recommended refrigerants, the company said it has continued to test various low global warming potential (GWP) refrigerants with the objective of determining suitable replacements for R-404A (globally) and R-134a (primarily for North America).
“The effect that HFO refrigerants have on compressor reliability is of extreme importance to Tecumseh,” the company said in a press release. “As previously reported, some HFO blends have been ruled out due to the higher discharge temperatures and negative impact on compressor reliability and life.”
