SYNTHETIC REFRIGERATION COMPRESSOR LUBRICANT
Shell Clavus AB 68 synthetic refrigeration compressor lubricant is formulated from the highest quality alkylate base stocks.
It is recommended for service where evaporator temperatures may be lower than (-45 degrees C) and where improved
performance and reliability are desirable.
Shell Clavus AB 68 Refrigeration lubricant is recommended for all refrigeration compressor types including reciprocating,
centrifugal and rotary. These lubricants are compatible with ammonia and CFC, HCFC refrigerants such as R12, R13, R22,
R114, R123, R124, R401A, R401B, R401C, R402A, R402B, R403, R500, R502 and R503 in both industrial and marine
applications. Shell Clavus AB oils are not compatible with R134A.
Shell Clavus AB 68 is fully compatible with conventional mineral oils and materials constructed of Mylar(TM), Polypropylene,
Viton(TM), Buna-N, Neoprene and Nylon(TM) elastomers.
Improved compressor efficiency.
Excellent high temperature stability.
Superior solubility characteristics with refrigera
Excellent compatibility with seal materials.
Outstanding low temperature properties.
Improved wear protection at elevated temperatures.
No deposit formation in low temperature systems.
Extended service life and longer drain intervals.
High degree of chemical stability.
Eliminates degradation and sludge formation associated with conventional mineral oils.
Prevents fouling of heat transfer surfaces and plugging of evaporators and expansion valves.
Improved resistance to foaming over conventional refrigeration oils.
