Panolin HLP SYNTH 32 obtains Bosch Rexroth fluid rating

(VENTURA, Calif.) — Panolin International has announced that HLP SYNTH 32 is the first and so far only eco-friendly hydraulic oil to be featured on the Bosch Rexroth RDE 90245 Fluid Rating List.

"Panolin HLP SYNTH is the first rapidly biodegradable hydraulic oil to obtain the fluid rating (ISO 15380 in combination with RFT-APU-CL test)," said Patrick Lammle, chairman of the board of directors of Panolin International.

HLP SYNTH was the first hydraulic oil to obtain the Blue Angel environmental award about 20 years ago and has already been approved by numerous manufacturers. Its inclusion on the Bosch Rexroth list means that HLP Synth now also bears the label of what is currently the most rigorous OEM test on the market.

Recent years have seen a sharp increase in the requirements to be met by hydraulic oils. Growing power density — the result of higher working pressures, motor speeds, oil circulation cycles and temperatures — has driven the development of hydraulic systems forward, imposing more demanding requirements on the hydraulic liquids used in these systems. These liquids have a decisive impact on the friction characteristics of the hydraulic components.

The ongoing technical development of high-performance hydraulic systems and suitability of new hydraulic media and additives are only partially reflected in the tests used to date. Whereas in the 1970s, specific power density was approximately 4 to 5 kW/kg pump weight, that figure, at over 8 kW/kg, had almost doubled by 2010. Today's hydraulic fluids must be carefully engineered to cope with these developments, i.e. smaller pump units with a higher output and a range of other efficiency-improving modifications to the hydraulic system.
