BIHOL (NSF H1)

BIHOL Hydraulic Oils are high-performance, rapidly biodegradable hydraulic lubricants based on rapeseed oil. They offer excellent lubricating properties and an extended operating temperature range. Developed as a replacement for mineral hydraulic oils, they help reduce environmental impact. HETG according to ISO 15380. Available in viscosity grades ISO VG 32/46.

BIHOL 32 and BIHOL 46 are NSF H1 certified and are therefore suitable for use in applications where incidental contact with food may occur. Learn more about NSF H1 certification

FAQ – BIHOL

What are the main properties and benefits of BIHOL oils?

Which standards does BIHOL comply with?

HETG: ISO 15380
NSF H1 – for BIHOL 32 and BIHOL 46 (food processing applications)
EU Ecolabel licence No. CZ/027/001
Environmentally Acceptable Lubricants (EALs) – US EPA VGP 2013

Are BIHOL oils NSF H1 certified?

Yes. BIHOL 32 and BIHOL 46 are certified according to NSF H1, which means they are suitable for use in food processing environments where incidental contact between the lubricant and food may occur.

What does NSF H1 certification mean?

What applications are BIHOL oils suitable for?

Designed for lubrication of hydrostatic and hydrodynamic machine systems, particularly suitable for hydraulic quick couplings in hydroelectric power plants, forestry, construction and agriculture. Ideal for applications where oil leakage into sensitive environments may occur.

What packaging options are available?

10 L canister
20 L canister
60 L drum
205 L drum
1000 L IBC
24,000 L – bulk delivery by tanker

Is BIHOL environmentally friendly?

Yes. BIHOL oils are rapidly biodegradable, non-toxic and minimize environmental impact while maintaining high performance.

Parameters

	BIHOL 32	BIHOL 46	Unit
Density at 15 °C	900 – 940	900 – 940	kg/m³
Kinematic viscosity at 40 °C	29 – 36	Viscosity is a physical quantity representing the ratio between shear stress and rate of change of velocity with respect to distance between adjacent layers during flow of a real fluid. 41 – 51	mm²/s
Kinematic viscosity at 100 °C	8.1	Viscosity is a physical quantity representing the ratio between shear stress and rate of change of velocity with respect to distance between adjacent layers during flow of a real fluid. 9.3	mm²/s
Pour point	< -20	The lowest temperature at which the tested sample ceases to flow upon gradual cooling, usually 3 °C lower than the flow point. < -20	°C
Flash point, COC	> 280	The lowest temperature at which enough vapors are released from the heated sample to ignite momentarily when approached by a small flame. > 280	°C
Viscosity index	> 190	The Viscosity Index (VI) indicates the change of kinematic viscosity of oils with temperature. Higher VI means less change of viscosity with temperature. > 190	-
Oxidation stability	> 100	Oxidation stability measured by RSSOT indicates the resistance of the oil to oxidation over time. > 100	Min
Biodegradability over 28 days	> 60	Biodegradable breakdown of the oil without harmful effect on fauna and flora. Biological degradation monitored by dissolved oxygen analysis over 28 days. > 60	%
