Shell PANOLIN S4 Stern Tube EAL 100

Description

Shell PANOLIN S4 Stern Tube EAL 100 is a special-purpose, non-emulsifying synthetic stern tube fluid formulated from fully saturated esters. It is designed to provide reliable lubrication and corrosion protection for stern tube bearings while offering readily biodegradable performance and low ecotoxicity. The fluid is an Environmentally Acceptable Lubricant (EAL) and carries the EU Ecolabel.

Key Features & Benefits

• Readily biodegradable: Achieves more than 60% biodegradation after 28 days according to OECD 301B.
• Environmentally acceptable lubricant: Designed for marine applications where reduced environmental impact is important.
• Fully saturated ester formulation: Provides strong resistance to oxidation and good hydrolytic stability, supporting extended fluid life.
• Excellent wear protection: Advanced additives help protect stern tube bearings under demanding operating conditions.
• Strong corrosion protection: Helps protect bearing and system components against corrosion.
• High viscosity index: Supports low-torque start-up at lower temperatures while maintaining lubricant film strength at higher operating temperatures.
• Excellent water separation: Non-emulsifying formulation and good demulsibility allow water to be separated from the lubricant.
• Good foam control: Helps maintain efficient lubrication and reliable system operation.
• Low ecotoxicity: Formulated to reduce environmental impact in the event of leakage or accidental release.
• Marine OEM approvals: Approved by SKF Marine, Wärtsilä, KEMEL, Lagersmit and Aegir-Marine.
