HYDRAUNYCOIL FH 4551

ISO 12922 ­ Category HFDU

FIRE RESISTANT HYDRAULIC FLUID ISO VG 68

HYDRAUNYCOIL FH 4551 is a fire resistant fluid based on a carboxylic ester. Its temperature operating range is comprised between -20 °C to +120 °C. It contains specific corrosion inhibitor to prevent corrosion of steel, copper, aluminium and other metals. HYDRAUNYCOIL FH 4551 is also readily biodegradable.

DESCRIPTION :

APPLICATION :

HYDRAUNYCOIL FH 4551 is intended for hydraulic equipments when the risk of fire is a concern. HYDRAUNYCOIL FH 4551 is widely used in high pressure equipments in steel and aluminium industry in which it has proven very efficient. The high level of biodegradability of HYDRAUNYCOIL FH 4551 is an additional benefit highly appreciated in tunnelling industry. HYDRAUNYCOIL FH 4551 is compatible with most of usual elastomers (see table below) and paintings. In most cases, HYDRAUNYCOIL FH 4551 can be used directly in existing systems - designed for mineral-oil based hydraulic fluids ­ without any modification. System conversion can be achieved by a straightforward drain-refill procedure. However, to keep the full benefit of fire resistance properties, ensure that the equipment is completely drained prior to fill it with HYDRAUNYCOIL FH 4551. Very good anti-wear and anti-corrosion performances High flash and auto-ignition points Good filterability Non-toxic High level of biodegradability
