ECOSURE HSE 46 is a biodegradable, high-performance anti-wear hydraulic oil (ISO VG 46) for heavy-duty operation from Vickers Oils, based on fully saturated renewable esters with state-of-the-art ash-free, zinc-free additives. The oil exceeds ISO 15380 (HEES category) and meets the US EPA definition of an environmentally acceptable lubricant (EAL) under the 2013 Vessel General Permit (VGP).
Use: CPP units, stabilisers, ramps, deck equipment, certain thrusters and heavy cranes – critical below-waterline applications where there is a risk of oil leakage into the marine environment. Also suitable for high-pressure hydraulic and circulation systems in industrial, mining, marine and mobile applications. Operating temperature −35 °C to +100 °C, recommended for longer exposure to high temperatures.
Benefits: Exceptional oil life – up to 12,000 h in ASTM D-943 DRY TOST and more than 800 min in ASTM D-2272 RPVOT, excellent oxidation and thermal stability, reduced deposit formation in hydraulic control systems for longer, smoother and more reliable operation, improved lubricity, superior demulsibility, good shear stability and long-term filterability, good seal compatibility, biodegradable and minimally toxic.
Technical profile: Viscosity 46 cSt at 40 °C (ASTM D7042), viscosity index 151 (ASTM D2270), pour point <−35 °C (ASTM D7346), flash point >180 °C (ASTM D92), density 0.905 kg/l at 15 °C (ISO 12185). Oxidation: up to 12,000 h in ASTM D-943 DRY TOST and >800 min in ASTM D-2272 RPVOT. Pump lubrication Eaton 104C/35VQ – approved, FZG anti-wear > load stage 12, ASTM D-130 copper corrosion – approved, ASTM D-665 rust (fresh and seawater) – approved, ASTM D1401 demulsibility – approved, elastomer compatibility (Nitrile, Viton, Teflon, Nylon, PTFE) – approved. Shelf life 5 years in unopened original packaging, stored away from direct sunlight.
Approvals/environmental profile: ISO 15380 HEES category (synthetic ester), VGP EAL according to US EPA 2013, Swedish Standard 15 54 34, Eaton Vickers 35VQ and 104C, Parker Hannifin Denison HF-1, HF-2, HF-6.
