Castrol Brayco Micronic SBF E is an environmentally leading barrier fluid specifically formulated using fully syntheticbase oil for use in subsea rotating equipment and where a barrier fluid is required. The fluid is specifically formulated toincorporate all the features required for reliable operation of high speed subsea gas compressors and subsea pumpsrunning under continuous duty cycle in the demanding subsea environment. This product has also been developed toprovide electrical insulation and cooling of high power electric motors. It provides operators with an environmentalalternative to conventional subsea barrier fluids, being fully compliant against North Sea OSPAR legislation (and testedin other required geographies).
Advantages
- All components tested in accordance with OSPAR environmental legislation.Environmental testing has been completed for compliance in other geographies.
- Electrical insulation properties provide additional protection against shorting in high power motors.
- Good lubrication performance in radial and axial bearings and seals systems.
- Low viscosity prevents shear and heat generation in high speed machinery.
- Fully compatible and miscible in all proportions with other products in the Castrol Brayco Micronic range.
- Fully compatible and miscible in all proportions with typical mineral oil based products, allowing easy upgrade ofexisting systems by top-up.
Application
- Specifically formulated for use in subsea pumps and compressors requiring an oil based barrier fluid.
- Electrical insulation properties ensure suitability for internal cooling of high voltage electric motors.
- Provides a barrier against seawater ingress and process fluid ingress into system hardware.
- Low pour point ensures operation down to -50ºC in areas where low ambient temperatures prevail.
