PREMIUM Hydraulic Oil (HEES)

PREMIUM Hydraulic Oil is ultimate performance, fully synthetic, zinc-free, readily biodegradable hydraulic oil based on top-tier fully saturated synthetic esters. A special additive package delivers outstanding extreme pressure properties, thermal oxidation resistance, anti-wear and non-foaming control. Because of the high Viscosity Index PREMIUM Hydraulic Oil provides extremely wide operating temperature range and greater fluid stability. PREMIUM Hydraulic Oil allows for extremely long oil-change intervals “lifetime fill” resulting in cost effectiveness and CO2 emissions reduction.

PREMIUM Hydraulic Oil is produced at viscosity classes: ISO VG 15/22/32/46/68/100

Industry Performance Standards

HEES : ISO 15380
EU Ecolabel licence no. CZ/27/001
Environmentally Acceptable Lubricants (EALs) US EPA Vessel General Permit 2013 (VGP)

PREMIUM Hydraulic Oil is designed to meet the most demanding requirements of hydraulic applications. PREMIUM Hydraulic Oil is particularly recommended for operations in environmentally sensitive areas (off-shore, marine, power plants, forestry, earth-moving, construction, agriculture, etc.)
