REFRIGERATION
AND AIR CONDITIONING CONTROLS By Arne H. Blom, Product Manager |
| HFC refrigerants and POE oils (Polyol Ester oils) have now largely replaced HCFC/CFC refrigerants and mineral oils. They have created new possibilities, but also new problems. Filter driers with high moisture adsorption have become a must and the polar molecular struc-tures in refrigerants and oils mean that activated aluminium oxide has been made redundant as the desiccant in filter driers. At the same time, sight glasses must react to moisture percen-tages much lower than before. |
