I have a question, I have a 100 hp Mycom mayekawa reciprocant compresor and the used refrigerant is freon R22, the technical data sheet of the oil said the viscosity is 56 cSt@100ºF, but when I sent the lubricant for analisys always the viscosity is minor, 43 to 45 cSt, I already sent a new sample of lubricant and the viscosity of the new oil is 56 cSt@100ºF, I want to know if the loose of viscosity is normal or what do you recommend in order to avoid this problem, the base stock of the oil is alquilbencene, any suggestions?
What is the best lubricant energy efficent for a refrigeration compressor that use freon R22?
