Which applications is BIO-HEPR 46 suitable for?

BIO-HEPR 46 is suitable for mobile and industrial hydraulic systems, construction machinery, forestry and agricultural equipment, and applications requiring environmentally friendly hydraulic fluids in sensitive ecosystems.

What is the recommended operating temperature range?

Recommended operating temperature range: -25 °C to +100 °C, with short-term temperature peaks up to 120 °C.

How should BIO-HEPR 46 be applied?

Apply using standard hydraulic system filling procedures. When switching from another hydraulic fluid, the system should be drained and, if necessary, flushed to ensure compatibility.

Parameters

Density at 15 °C	~0,850 ± 0,01 g/cm3
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. 41-51 cSt
Kin. viscosity at 100 °C	8,1 cSt
Pour Point	The pour point of a liquid is the temperature below which the liquid loses its flow characteristics. < - 25 °C
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. > 280 °C
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. 150
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 %
