Hydraulic Oil PLUS (HEES)

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

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/27/001
Environmentally Acceptable Lubricants (EALs) US EPA Vessel General Permit 2013 (VGP)

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.)

Parameters

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
Kin. viscosity at 100 °C	9-10,5 cSt
Viscosity index	The viscosity index (VI) indicates the change in kinematic viscosity of oils with temperature. A higher VI means less change in viscosity with temperature. BIONA bio-oils with a VI of up to 220. > 180
Density at 15 °C	910-930 kg/m3
Flash point	The lowest temperature at which enough vapor escapes from a heated sample above its surface into the air that the resulting mixture of vapor and air ignites when an auxiliary flame is brought close to it and then extinguishes again. >250 °C
Pour Point	The pour point of a liquid is the temperature below which the liquid loses its flow characteristics. <-40 °C
Biodegradability in 28 days	Biologically sufficiently rapid decomposition of oil without effect on fauna and flora. Biological decomposition monitored by dissolved oxygen analysis over 28 days. >60
ISO-VG viscosity classification	ISO VG 46
Base oil	Synthetic oil
