Compressor Oils Today

Compressors are precision engineered. To protect them and keep them reaching maximum performance, you need compressor oil that will suppress foaming to keep optimum efficiency and release trapped air. It also needs to separate out condensed water fast. Using the right oil is vital as it will help to reduce wear. What this means for you is you won’t need to replace your compressor so often which saves money and also down time. It will also keep the compressor working at its’ maximum potential for longer giving you better results.

Shell’s Corena range of compressor oils now includes the latest advance synthetic oils that can last up to three years. These give protection that enhances wear in both high temperatures and lengthy operations.

Changing compressor oils saves Turkish Company 50%

Pilsa Plastic Products Inc. Is a Turkish company which has been an industry leader for over 40 years. They were very unhappy with the disappointing performance of the usual lubricants. Worse still, their analysis showed that the oil had poor stability which made it necessary for them to drain it every 5,000 hours. This brought productivity to a standstill and involved time and labor costs – making their operational costs unfeasibly high.

They called in the Shell Lubricant team who monitored and analyzed the performance of their current oil using Shell LubeAnalyst. The team recommended that Pilsa should try Shell Corena S4 R 68 and implement technical training.

Pilsa took their advice and found that it cut their operational costs in half. The necessity for oil draining went from every 5,000 hours to 10,000. The savings resulted from

  •         Lower oil consumption
  •         Lower labor costs
  •         Less oil waste which costs to dispose of
  •         Better maintenance processes

Their company reports showed that Pilsa saved US$12,185 in the first year after implementing the change to Corena S4 R 68.

Performance benefits

Corena S4 R 68 offers enhanced resistance to both thermal and chemical breakdown. This helps to prevent deposits forming on rotating components and in sliding vane slots to ensure continuous operation at optimum performance. Noticeably lower levels of deposits help to keep internal surfaces exceptionally clean, especially in both oil/air separator and coalescer systems.

If you’ve been facing the same issues of poor thermal and oxidation stability and the subsequent need for frequent oil drainage, it might be worth considering a change.

What is Heat Transfer Oil?

Heat Transfer Oil is a coolant. Coolants are needed to flow through a device to stop it overheating. The oil does this by transferring the heat that the device is producing to other devices. The other devices either use or dissipate it.

The best type of coolant has thermal capacity. This is the ratio of the heat added to, or taken away from a device to the resulting change in temperature. [1] It should also have low viscosity, be inexpensive, non-toxic and chemically inert so that it doesn’t cause corrosion of the system.

The word coolant is usually used by the auto and HVAC industries. Industrial processing used ‘heat transfer fluid’.
