Fire-Resistant Hydraulic Fluids AP

Fire-Resistant Hydraulic Fluids — Anvol and HFC/HFD Ranges

When a hydraulic leak near a hot surface could end in fire, conventional HLP is not enough. Anvol delivers ISO 15029 ignition resistance without compromising pump life.

Quick Answer

Castrol Anvol PE (phosphate ester) and Anvol HFC (water-glycol) fire-resistant hydraulic fluids for foundries, steel mills, glass plants, granite quarries and coal-handling applications where conventional mineral hydraulic oil presents fire risk. HFC water-glycol fluids for the lowest fire risk in line-of-sight to molten metal or hot rolling. PE phosphate-ester fluids for higher pressure systems requiring true fire-resistant performance with seal-friendly characteristics.

Frequently Asked Questions

HFC vs HFD — which do I need?

HFC (water-glycol) is the cheaper, more widely used choice for 40–70 bar systems where pump wear can be tolerated. HFD (phosphate ester) is essential above 200 bar and where a water-containing fluid is unacceptable (gas-turbine controls).

Can I convert from HLP to HFC without changing pumps?

Partially. HFC reduces pump life significantly; you must de-rate pumps by 25–35% and switch all seals from NBR to viton. Flushing protocol is strict — any residual mineral oil causes phase separation.
