Delivering value for you
Low volatility and good ammonia immiscibility which helps prevent oil reaching the evaporator, promoting refrigeration efficiency and minimizing maintenance. The low pour point and high viscosity index ensures that oil which does reach the evaporator will drain more rapidly than a naphthenic oil.
Minimal make-up oil is required because this product resists “carryover” to the refrigeration system’s low temperature side.
Minimum sludging and formation of harmful deposits in the high temperature environment of the compressor which promotes long equipment and lubricant life while minimizing maintenance.
Group II base stock properties allow the oil to maintain a stable viscosity, staying in grade longer than a naphthenic refrigeration oil.
Effective protection for critical parts of the compressor provided by high viscosity index, low foaming tendency, and inherent antiwear properties. The oil maximizes equipment life and life to overhaul by providing effective lubrication to all moving parts.
Resistance to thermal degradation can allow customers to extend drain intervals.
Applications
Although designed for use in ammonia refrigeration systems, Capella P 68 is also recommended for use in systems using refrigerant R-22 and R-502 - provided the evaporator temperature is above -32°C (-25°F).
It is not recommended for systems using refrigerant R-12 or R-134a.
