Seal oil systems are used extensively in the offshore industry particularly on production machinery.
They are used on equipment where there are significant pressure differentials from the internal process and the atmosphere such as axial gas compressors. Seal oils are normally thin, have good thermal stability and are free from solid, anti-wear or EP additives. Viscosity is critical and OEM guidance is required, always consult your Castrol Technical Service Engineer.
Transcal LT is a low temperature mineral heat transfer fluid that combines such characteristics as low vapour pressure, and high levels of thermal stability, specific heat and thermal conductivity with exceptional low temperature fluidity. The product is recommended primarily for non-pressurized closed liquid phase heating systems that incorporate both heating and cooling branches.
Transcal N is a high quality mineral oil possessing low vapour-pressure characteristics as well as high levels of thermal stability, specific heat and thermal conductivity. Transcal N is recommended for non-pressurised, closed liquid-phase heating systems operating at bulk-fluid temperatures up to 320ºC, and a maximum film temperature of 340ºC.Such systems are used widely in the food, construction, plastics, timber, oil and gas processing and on ships and where waste heat is extracted from flue gases.
HYSPIN SPINDLE OIL E5 & 10
The Castrol Hyspin Oil range is based upon highly refined mineral oil enhanced with rust and oxidation inhibitors and formulated especially for the lubrication of high speed and precision machine tool spindle bearings. Designed for use in all types of spindle bearings, including high-speed spindle bearings. Primary choice for seal oil systems used offshore.
Castrol Magna grades are a range of high quality additive-free oils possessing inherently good resistance to oxidation and good demulsification properties. Castrol Magna lubricating oils are suitable for a variety of applications such as the lubrication of bearings, spindles and, using the heavier viscosity grades, moderately loaded gearboxes. They may also be used in vacuum pumps and hydraulic systems where an ‘ISO HH’ fluid type is required.
Hyspin VG 22
Castrol Hyspin VG 22 is a low viscosity mineral oil intended for use as the sealing medium in oil film barrier seals on rotating equipment such as gas compressors and main oil line pumps. Castrol Hyspin VG 22 has excellent low temperature properties and high temperature stability in order to give good performance over a wide range of conditions and to maximise seal life.
Perfecto MSO ASA III
Castrol Perfecto MSO ASA is a highly stable mineral oil for use in oil film barrier seals on rotating equipment and gas compressor applications. It possesses improved electrical conductivity reduces the risk associated with static electricity discharges in process gas equipment, particularly where inert gas blanketing of oil reservoirs is not available. Perfecto MSO ASA III contains no additives which form films of any kind, ensuring that oil seal life is not compromised by the use of an anti-static oil. Always check your equipment manual and consult with a Castrol Technical Service Engineer to choose the right product for the right application.
