BIO Hydraulic Oil PLUS (HEES)

LUBECO™ Hydraulic Oil PLUS presents a high performance, fully synthetic, zinc-free, readily biodegradable hydraulic fluid based on a mixture saturated synthetic esters. A special additive package delivers excellent extreme pressure properties, thermal oxidation resistance, anti-wear and non-foaming control.

Because of the high Viscosity Index Hydraulic Oil PLUS provides extremely wide operating temperature range. It allows for very long oil-change intervals resulting in cost effectiveness and CO2emissions reduction.

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

Industry Performance Standards

  • HEES : ISO 15380
  • EU Ecolabel licence no. CZ/27/022
  • Environmentally Acceptable Lubricants (EALs) US EPA Vessel General Permit 2013 (VGP)
  • MPI Approved C15 Maintenance Compound (Non-Dairy)

Areas of Application

Hydraulic Oil PLUS is specifically designed for use in all hydraulic systems, both hydrostatic and hydrodynamic. Hydraulic Oil PLUS is particularly recommended for operations in environmentally sensitive areas (forestry, marine, hydropower plants, earth-moving, construction, agriculture, etc.)

ISO-VG viscosity classification ISO VG 46
Base Oil Synthetic oil
Kin. viscosity at 40 °C The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. 46 cSt
Density at 15 °C 912 kg/m3
Kin. viscosity at 100 °C 9,2
Viscosity Index Viscosity Index (VI) is a measure of the change of viscosity with temperature. The higher the VI, the less is the viscosity affected by changes in temperature. 190
Flash Point >250 °C
Pour Point The pour point of a liquid is the temperature below which the liquid loses its flow characteristics. -40 °C
Corrosion on copper 1a
FZG Test 12
Biodegradability in 21 days >90 %
