SOMELA RAVUS ISO 68

SOMELA RAVUS ISO 68 is a naphthenic ashless oil for the lubrication of refrigeration compressors operating with ammonia and hydrocarbons. Its ISO VG 68 viscosity, higher viscosity, for heavy-duty refrigeration compressors, offers stable lubrication in extreme cold. Its formulation is zinc-free.

Naphthenic ashless oil designed for the lubrication of refrigeration compressors using ammonia (R717), as well as hydrocarbons such as R600a (isobutane), and also compatible with classic halogenated refrigerants such as R12 and R22. Its naphthenic base ensures excellent miscibility and proper flow at low temperatures, offering stable lubrication even with very low evaporation. It stands out for its thermal and chemical stability in contact with ammonia, guaranteeing long operating periods without degradation or deposit formation.

Advantages in use:

✔ Special for ammonia (R717) and hydrocarbons (R600a)

✔ Compatible with classic R12 and R22

✔ Naphthenic base: great flow and miscibility in cold

✔ Thermal and chemical stability against ammonia

✔ Minimal sludge formation and good internal cleaning
