- PRODUCT DESCRIPTION AND APPLICATIONWestron® R 507A is a non-ozone depleting, azeotropic blend of HFC refrigerants R-125 and R-143a.
R-507 is blended to match the properties of R-502, making it a good refrigerant for some medium and most low temperature Refrigeration applications especially for use in new Refrigeration equipment such as food display and storage cases, Cold storage rooms, Transport Refrigeration, Process refrigeration, Boats and Deep Sea Trawler for Refrigeration Purpose. Westron ® 507 is an HFC replacement option for R-22 and R-502 for commercial Refrigeration systems and It can be used in new and existing systems, and provides very similar performance to R-502 over the entire operating range.LubricationWestron® 507A requires Polyester (POE) Lubricant to ensure complete miscibility between Oil and refrigerant. Miscibility is important for Oil return to the compressor especially in large Systems with long runs of Piping. Use Manufacturer’s manual for the safety for the equipment’s.
