Universal PAG refrigeration oil for R1234yf and R134a mobile air conditioning (MAC) systems



RENISO PAG 1234 is based on special double-endcapped polyalkylene glycols (PAG) and contains a high-performance additive system in order to cope with the special requirements in mobile air conditioning Systems (MAC).Especially the chemical stability in combination with the new refrigerant R1234yf was optimized by choosing a new additive technology for RENISO PAG 1234. Also the refrigerant miscibility of RENISO PAG 1234 is favourable: a safe oil transport is guaranteed, no matter if R134a or R1234yf is used as refrigerant. It is suitable for both HFO-1234yf and R134a.RENISO PAG 1234 shows excellent wear protection in all common compressor types, especially axial piston compressors. Effective antiwear (AW) additives combined with the special double-endcapped PAG base fluid secure outstanding lubrication properties.RENISO PAG 1234 also fulfills highest requirements with regard to the thermo-chemical stability in R1234yf cycles.RENISO PAG 1234 fulfills and exceeds DIN 51503 KD.
