Tecumseh Continues Testing, Outlines Its Position on Refrigerant Transition
Latest update includes approvals for HC and HFO refrigerants
In follow-up to the document that Tecumseh issued in June 2015 regarding recommended refrigerants (click here to view), the company has continued to test various low-global warming potential (GWP) options with the objective of determining suitable replacements for R-404A and R-134a.
For commercial refrigeration equipment employing the use of remote condensing units, Tecumseh has approved R-449A and R-452A as acceptable alternatives to R-404A. However, due to the higher discharge temperatures prevalent with R-449A, compressors used in these applications must maintain strict compliance with the requirements outlined in the relevant Tecumseh Policy Bulletins and Application Guidelines. Tecumseh is in the process of releasing a full line of R-449A compressors and associated condensing units for low-, medium-, and high-temperature commercial refrigeration applications.
