- Klüber Summit RPA 68 has been designed especially for the lubrication of highly loaded screw-type and reciprocating piston compressors which are operated with ammonia (R717) as refrigerant.
- Klüber Summit RPA 68 is particularly suitable for compressors that were previously run with mineral oils. Unlike polyalphaolefins, Klüber Summit RPA 68 is neutral towards most neoprene seals used in refrigerating plants, therefore leakage is not to be expected.
- Due to the synthetic base oil of Klüber Summit RPA 68, oil carryover into the refrigeration cycle is much lower than with conventional mineral oils, which helps to reduce oil consumption.
- The viscosity of the oils remains consistent for a long time, due to the fact that only a few highly volatile fractions are contained in the oil. Oil changes due to the increase in viscosity can be extended considerably.
- The base oil offers high chemical stability, particularly to ammonia, the typical blackening of conventional mineral oils or deposits in the refrigeration cycle are prevented and oil change intervals can be extended.
- Our experience gained in practice has shown that Klüber Summit RPA 68 can be used for evaporating temperatures as low as -53°C (where mineral oils no longer flow) depending on the operating conditions. Klüber Summit RPA 68 protects against wax-like deposits, thus increasing the efficiency of the refrigeration plant
