GST® OIL

32, 46, 68, 100

PRODUCT DESCRIPTION

GST® Oils are formulated with premium base oil technology designed to meet the critical demands of:

� non-geared gas, steam, and hydroelectric turbine bearing lubrication

� reduction gear lubrication in marine operations

They are an excellent recommendation for many other industrial applications including air compression where

R&O type oils are recommended.

CUSTOMER BENEFITS

GST Oils deliver value through:

� Exceptional oxidation stability for long service life at elevated temperatures. Formulated with premium base oil technology and an ashless, zinc-free formulation.

� Rust and corrosion protection

� High viscosity index helps ensure minimum viscosity change when variations in temperature occur.

� Minimum foam helps prevent sump overflow or erratic governor operation.

� Fast air release minimizes possibility of pump cavitation in systems with high circulation rates and small reservoirs.

� Exceptional thermal stability minimizes deposit formation.

� Rapid water separation keeps water in oil to a minimum.

� Hydraulic fluid service — GST Oils 32, 46 and 68 are excellent hydraulic fluids in low pressure systems up to 1000 psi.

� Air compressor lubricant when OEM recommends

R&O type oil.

FEATURES

GST Oils are formulated with premium base oil technology and an ashless, zinc-free formulation that provides exceptional oxidation stability, water separability, and protection against rust and corrosion.

Higher temperatures in advanced gas and steam turbines require circulating system oil with exceptional high temperature stability. GST Oils have outstanding thermal and oxidation stability.

Nonvolatile oxidation inhibition minimizes the evaporative loss of the inhibitors, a common problem with turbine oils where bearing temperatures are high and system capacities are limited. With retained oxidation resistance for long periods under high temperature conditions, GST Oils will promote long oil service life and help minimize turbine down time.

Corrosion inhibition protects costly turbine shafts and gears from corrosion and rusting.

GST Oils have excellent demulsibility characteristics which allow these oils to maintain a high film strength coating on critical wear points of bearings and gear reducers and assure fast removal of water contamination.

Foam inhibition helps prevent sump overflow and erratic governor operation.
