FREEZPLUS PARA VG-68

Product Description

FREEZPLUS PARA VG 68 is refrigeration compressor oil based on paraffinic mineral oil. The moisture content of FREEZPLUS PARA VG 68 oil is very low when the oils are packaged. Every precaution should be taken to keep the oils dry to avoid the formation of ice in expansion valves, and to limit the risks of oil degradation, copper plating, etc. It can be used for evaporating temperatures as low as -39 °C depending on the operating conditions. As the base oil of FREEZPLUS PARA VG 68 is highly refined, oil carryover into the refrigeration cycle is much lower than with conventional mineral oils, which helps to reduce oil consumption.

Benefits

·        Low maintenance costs due to extended oil change intervals and reduced oil consumption.

·        Easy compressor oil conversion due to neutral behavior towards seals.

·        High efficiency of the refrigerating plant due to reduced oil deposits.

·        Low oil carryover and consumption compared to naphthene-based mineral oils.

Low operating costs due to long service life of filters and oil separators

Recommended Usage

  • FREEZPLUS PARA VG 68 has been designed especially for the lubrication of screw-type and reciprocating piston compressors which are operated with ammonia (R717) as refrigerant.
  • It is particularly suitable for compressors which were previously run with mineral oils. This product is neutral towards most neoprene seals used in refrigerating plants; therefore, leakage is not to be expected.

·        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 avoided.

·        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 considerably
