About
SZC PAO/AB (NH) Synthetic oil
SZC® NH Synthetic Series are a full synthetic oils blend of PAO and AB based ammonia refrigeration compressor oils used in industrial systems, which have demonstrated outstanding resistance to thermal and oxidative degradation. Even in the worst operating conditions, SZC Synthetic NH Series will reduce sludge and deposit formation, hence avoiding or minimizing valve or filter plugging.
SZC® NH Synthetic Series are compatible with most refrigerants except sulphur dioxide. They are not recommended for use with HFC refrigerants. is miscible with CFC and HCFC refrigerants and maintains lubricity. It is formulated to protect cast iron and remains stable in the presence of CFC and HCFC as well as with ammonia.
Compared to mineral based refrigerating oils SZC® NH Synthetic deploys higher thermal stability and lower volatility, which makes the product the better choice in case of high compressor discharge temperatures. At the same time, the low pour point and very low floc points enable lower minimum evaporator temperature over mineral based refrigerants.
