The CPI-1508 Series compressor lubricants are formulated using a polyalkylene glycol (PAG) base fluid combined with a high performance additive package. These lubricants are specifically formulated to give negligible dilution with hydrocarbon gases.
These compressor lubricants feature excellent protection against hydrogen sulfide (H2S) in the gas stream. Corrosion protection, oxidative and thermal stability enable the use of these lubricants over a wide range of temperatures without varnish or deposit formation. The high viscosity index (VI) and negligible hydrocarbon dilution enables the CPI-1508 Series lubricants to operate over wide ranges of temperature and gas composition with small changes in viscosity
compared to other types of lubricants.
The CPI-1508 Series fluids are especially advantageous in compressors operating in harsh chemical environments, particularly sour gas (H2S present) applications, due to their robust formulation.
