PROGILINE® HF FOR HYDRAULIC SYSTEMS
A fire hazard may exist wherever the accidental escape of pressurized hydraulic fluid may occur near a flame, molten metals or hot surfaces. Major fire risk exists, for example in the mining industry, forging industry, die-casting and welding applications.
PROGILINE HF-C 4636 and 4643 are water-glycol based fire resistant hydraulic fluids which greatly reduce the risk of fire upon accidental release without compromising the performance or reliability of hydraulic system components.
PROGILINE HF-C provides excellent protection against liquid and vapor phase corrosion, high levels of wear protection and good foam resistance. Low pour point ensures consistent performance over a wide temperature range.
PROGILINE HF-C 4636
This product has a water content of 36% and is recommended for use where a combination of optimal lubricity characteristics and fire-resistance are required, for example in metal die casting operations.
PROGILINE HF-C 4643
This product has a water content of 43wt% and is particularly recommended for use where the highest safety margin is needed, for example mining applications.
PROGILINE HF-C CONC
This product is a concentrated form of HF-C fluid which enables the formulator to derive both PROGILINE HF-C 4643 and PROGILINE HF-C 4636 by further blending of the concentrate with Di-ethylene Glycol (DEG) and water.
A thorough draining and flushing procedure is essential when converting from other fluids to water-glycol based fluids. Systems filled with phosphate ester should be flushed with mineral oil prior to undertaking a further flushing procedure with HF-C.
