Manufacturer's description

Hydraulic fluid – high-performance, readily biodegradable saturated synthetic esters. Shell PANOLIN S4 HLP Synth is our highest-performing and industry-leading biodegradable saturated ester (HEES) type synthetic hydraulic fluid. The only Bosch-approved HEES fluid. The special zinc-free additive technology, formulated with high-performance fully synthetic saturated esters, delivers increased machinery efficiency through improved oil life and premium wear protection. Particularly suitable for use in environmentally sensitive areas and in stationary and mobile hydraulic systems, including construction, earthmoving and forestry.

Applications

• For stationary and mobile hydraulic systems, including earthmoving, forestry, construction and hydroelectric applications. Compressors, lubrication systems for
• high and shear-stable, contributing to increased hydraulic efficiency compared with a typical HM mineral oil. bearing and oil circulation systems and marine hydraulic systems. Specifications, approvals and recommendations
• For the full list of equipment approvals and recommendations, please consult your local Shell technical helpdesk. Compatibility and miscibility: It is strongly recommended that an oil sample be taken from the system after changeover and analysed via the Shell Rapid Lubricants Analysis service, to confirm that the new fluid charge is fit for use.
• This lubricant must not be mixed with other biodegradable hydraulic fluids, in order to ensure that the fluid's environmental properties and performance are maintained. The system should be drained and flushed thoroughly when changing fluids; guidance on fluid change-over can be found in ISO 15380 Annex A. This lubricant is compatible with fluoroelastomers (FPM/FKM) such as Viton. Other seal materials and system components, such as paints, may be adversely affected, and advice should be sought from the respective manufacturers.

Standards & approvals

• ISO 15380: 2016 HEES

  Biodegradable hydraulic fluid : 2016 HEES — ISO 15380

  The 2016 issue of the biodegradable hydraulic fluid standard, synthetic ester class.

• Biodegradabil OECD 301B >60%

  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.
