Hydraulic fluid - high performance, readily biodegradable, saturated synthetic esters. ISO 32,46,68 Shell PANOLIN S4 HLP Synth, the first Bosch approved HEES fluid, is our highest performance and industry leading biodegradable saturated ester (HEES) type synthetic hydraulic fluid. Shell PANOLIN S4 HLP Synth is formulated with special zinc-free additive technology, and high-performance fully synthetic saturated esters. Shell PANOLIN S4 HLP Synth offers increased machinery efficiency through enhanced oil life and premium wear protection. Particularly suited for use in environmentally sensitive areas and in stationary and mobile hydraulic systems including construction, earthmoving and forestry.
Bosch Rexroth RE 90245 — hydraulic fluid rating list
Bosch Rexroth's list of hydraulic fluids rated for use in its own pumps and motors. A fluid is listed after passing wear testing on axial piston pumps.
Biodegradable hydraulic fluid HEES — ISO 15380
The international standard for biodegradable hydraulic fluids; class HEES is the synthetic ester type, the most used where a leak would reach water or soil.
OECD 301B biodegradability above 60 %
A test result rather than a norm: OECD 301B measures the carbon dioxide evolved over 28 days. Above 60 % counts as "readily biodegradable", the threshold the environmental labels require.
Japanese Eco Mark environmental certification
