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.

Performance & benefits

• Enhanced oil life: designed to help equipment operate without interruptions, with multiple field examples of lifetime filling; has an outstanding dry TOST life of over 6000 hours (modified ASTM D943 test) and good oxidative stability, reducing fluid degradation, filter blockage and viscosity increase, helping prevent component failures and related parts and labour costs.
• Premium wear protection: designed to help equipment operate without interruptions, offering exceptional wear protection for hydraulic equipment and strong protection against sludge and varnish build-up.
• Designed to protect even in cold climates: good cold-flow behaviour enables a safe start even in cold conditions, reducing the risk of metal-on-metal wear; shear-stable, high-viscosity-index fluids help enable increased hydraulic efficiency compared with a typical HM mineral oil.
• Lower environmental impact: recommended for environmentally sensitive areas, with reduced impact from leaks or accidental spillage compared with conventional mineral oils; readily biodegradable - over 60% in 28 days in the OECD 301B test - and low ecotoxicity, tested against the OECD 201, 202 and 203 standards.

  Oxidation stability test method for turbine-type oils, part 3

  ISO 4263 sets out test methods for determining oxidation characteristics of inhibited turbine-type/hydraulic oils; part 3 describes a dry TOST variant.Source

• OECD 301B

  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.
