Castrol Biobar 46 Environmentally Responsible Hydraulic Fluid:
Castrol BioBar is a range of environmentally acceptable hydraulic fluids which can replace conventional mineral oils in hydraulic equipment where leakage or spillage may result in escape into the marine environment.
Castrol BioBar hydraulic fluids are formulated from synthetic ester base oils which are selected to give a wide operating temperature range and long service life.
Extensive testing of Castrol BioBar and hydraulic system components (in particular, elastomer seals) has confirmed good compatibility with standard components, which can allow conversion of existing equipment without the need for major changes.
Castrol BioBar hydraulic fluids have been tested and registered according to OSPAR (Oslo and Paris Convention for the Protection of the Marine Environment of the North-East Atlantic) requirements and therefore meet the definition of an Environmentally Acceptable Lubricant (EAL) ) under the US Vessel General Permit for Discharges Incidental to the Normal Operation of Vessels (VGP) 2013.
