NEXT GPL PAG-WS
Water Soluble PAG Gas Compressor Lubricant (Series 162)
Water-soluble polyalkylene glycol (PAG) copolymer lubricant for medium- to heavy-hydrocarbon gas compression, high-pressure service, and high-temperature heat pumps. The 1:1 EO:PO chemistry limits the uptake of high-molecular-weight hydrocarbons, maintaining operating viscosity where heavy working fluids readily dissolve into most lubricants.

Product Overview
NEXT GPL PAG-WS is a 1:1 ethylene oxide to propylene oxide (EO:PO) polyalkylene glycol copolymer. Its EO:PO balance limits the uptake of heavier hydrocarbons, which typically reduce in-service viscosity, making it ideal for high-pressure applications and systems handling butane, pentane, and isopentane. Water solubility simplifies equipment cleaning and flushing.
In hydrocarbon refrigeration and high-temperature heat pumps, NEXT GPL PAG-WS maintains viscosity at condensing temperatures, supported by a viscosity index up to 248. Its thermal and oxidative stability, with carbon and varnish control, keeps compressors clean. Low volatility limits lubricant carryover, and corrosion inhibition protects components in sour gas (H₂S) service.

Key Features
Resists Heavy Hydrocarbon Dilution
1:1 EO:PO chemistry maintains viscosity under medium to heavy hydrocarbon exposure.
High-Pressure Service
Low gas dilution sustains film strength as pressure drives more gas into solution.
Viscosity Index up to 248
Consistent lubrication from suction to discharge temperatures.
Sour Gas Protection
Corrosion inhibition protects components in H₂S-containing gas streams.
Oxidation Resistance
Resists degradation and deposit formation over extended service intervals.
