KLEA404A KLEA134a Refrigerant(R134a制冷劑)
Widely accepted as the most appropriate alternative for R-12 over the majority of the application range for both retrofit and new equipment. A very good match to R-12 for air conditioning, high and medium temperature usage. Some low temperature (-20C to -30C) R-12 applications may benefit from the use of an HFC blend from the R407-series such as R-407D, an R-500 and low-temperature R-12 alternative.
