Product Description
Shell Corena S4 R is a high-performance synthetic lubricant that provides exceptional protection for vane and screw compressors. Its advanced additive technology enables long-lasting protection for compressors with oil change intervals of up to 10,000 hours, and up to 12,000 hours in certain applications. Shell Corena S4 R also meets the requirements for bearing and circulating system oils or anti-oxidant and anti-rust oils (ISO VG 32-68).
Performance Advantages
Long Oil Life, Reduced Maintenance Costs
Shell Corena S4 R offers a long oil life, with a recommended oil change interval of up to 10,000 hours, even when operating at high discharge temperatures above 100°C (subject to manufacturer approval). In certain applications, this can be extended to 12,000 hours.
The advanced formulation of Shell Corena S4 R has the following characteristics, which help to extend oil change intervals:
Excellent thermal and chemical stability.
Prevention of deposit formation on rotating components, such as vane slots, in screw and vane compressors.
Very low levels of deposit formation, which helps to keep internal surfaces clean, particularly in oil/air separators and combined systems.
Oil change intervals are influenced by factors such as inlet air quality, load cycles, and ambient environment. For humid and hot climates, such as those found in the Asia-Pacific region, a shorter oil change interval is recommended (consult equipment manufacturer for guidance).
Excellent Wear Protection
Shell Corena S4 R provides additional corrosion and wear protection for metal surfaces.
Its high-performance, low-ash anti-wear system helps to extend the life of critical components, such as bearings and gears, in demanding applications.
Maintaining System Efficiency
Shell Corena S4 R allows for quick air release, with minimal foaming, ensuring reliable system operation, even in cyclic working conditions.
It provides reliable start-up and continuous compressed gas stability.
Shell Corena S4 R has low volatility and oil carryover, providing high air quality and reducing oil consumption.
Main Applications
Rotary Vane and Screw Compressors: Shell Corena S4 R is suitable for use in single-stage or multi-stage compressors with oil-bath or oil-injected lubrication systems.
Severe Operating Conditions: Shell Corena S4 R can also be used in applications with high ambient temperatures, where oil temperatures cannot be reduced to normal levels, as well as in high-humidity environments.
Bearings and Circulating Systems Oil: Shell Corena S4 R can effectively inhibit deposit formation, improve low-temperature fluidity, and reduce equipment operating temperatures, making it fully suitable for use as a fully synthetic bearing and circulating system oil or as an anti-oxidant and anti-rust oil (ISO VG 32-68).
