Shell Gas Compressor Oil S3 PY 220
Special Application Ethylene Gas Compressor Oil
Shell Gas Compressor Oil S3 PY lubricants are synthetic blends designed for total loss lubrication of the cylinders of reciprocating hypercompressors in the manufacture of low density polyethylene (LDPE), including LDPE used in special applications such as food, pharmaceuticals and cable insulation, and ethylene vinyl acetate (EVA). Low feed rates and high quality components help ensure minimal impact on production quality of the finished polymers.
Performance, Features & Benefits
- Outstanding wear protection
- Maintaining production efficiency
Main Applications
- Extreme high pressure hypercompressors
Shell Gas Compressor Oils S3 PY lubricants have been in widespread use in hypercompressor applications for over 10 years.
The ISO 220 viscosity grade provides low feed rates for lower oil content in the end-polymer but requires the use of elevated temperature line heating.
The ISO 150 grade allows the use of cylinder feed systems with standard trace heating.
- Food grade applications
Shell Gas Compressor Oil S3 PY lubricants meet the requirements of the US FDA for incidental food contact.
- Pharmaceutical grade applications
The oils are suitable for use in manufacture of polymers for use in applications where they will be in contact with pharmaceuticals.
- LDPE insulation
Use of Shell Gas Compressor Oil S3 PY lubricants enable production of LDPE with good dielectric properties, suitable for cable insulation.
- FDA/USA 21 CFR 178.3570 for incidental food contact
- European Regulation 10/2011, for plastics used in food contact
- The base fluid meets the requirements of FDA/USA 21 CFR 178.3620 for medicinal white oils.
- Seal Compatibility
Shell Gas Compressor Oil S3 PY is compatible with all sealing materials commonly used in hydercompressors.
