Castrol Anvol fire-resistant hydraulic fluids — Anvol PE (phosphate ester HFDR for high-pressure servo and proportional systems with seal-friendly characteristics), Anvol HFC (water-glycol HFC for the lowest fire risk in line-of-sight to molten metal), Anvol WG46. Per ISO 12922 HFDR / HFC standards. Vasundhara Specialities supplies the full Anvol range across AP and Telangana for foundries, steel mills, granite quarries and any hydraulic system where conventional mineral oil presents fire risk.
Complete Castrol coverage across the castrol anvol fire-resistant fluids family.
Phosphate-ester fire-resistant hydraulic fluid per ISO 12922 HFDR. ISO VG 32, 46, 68. For high-pressure hydraulic systems including servo and proportional valve installations. Seal-friendly (Viton/FKM compatible — but NOT compatible with NBR/Buna-N — full system seal review required before changeover). Excellent fire-resistance via auto-extinguishing characteristics.
Water-glycol fire-resistant hydraulic fluid per ISO 12922 HFC. 35-45% water content. ISO VG 46 nominal. The highest fire-resistance class — water content directly suppresses any fire-propagation risk. For service in line-of-sight to molten metal (foundry pour-deck, steel-mill stand, glass-plant gathering).
Premium water-glycol HFC variant with enhanced anti-wear and anti-corrosion performance. For long-life HFC service in demanding industrial-foundry hydraulic systems.
Specialty fire-resistant fluids: Anvol HFAE (high-water content emulsion >95% water), Anvol HFAS (synthetic aqueous solution). For mining roof-supports, longwall hydraulics, and other water-content-mandatory service.
Where the fire-risk assessment shows conventional mineral hydraulic oil is acceptable, Castrol Hyspin AWH may be a more cost-effective choice — see our Hyspin page. Anvol is specifically for service where mineral cannot be used.
Standard property values across the range. TDS / MSDS / per-batch COA available on enquiry.

Where Castrol Anvol Fire-Resistant Fluids ship from our Hyderabad warehouse — by industry segment + application profile.
Anvol HFC for foundry pour-deck hydraulics, ladle-tilt actuators, mould-handling press hydraulics. Direct line-of-sight to molten metal — water-glycol provides the highest fire-resistance class.
Anvol HFC for hot-strip-mill stand hydraulics + slab-mill mould-oscillation hydraulics. Anvol PE for cooler upstream hydraulic systems where servo-valve precision is critical. SAIL, RINL, JSW, Tata Steel installed base.
Anvol HFC for IS-machine plunger hydraulics, gathering-station hydraulics + float-glass tin-bath gear. High-temperature glass-melt environment makes mineral hydraulic oil unacceptable.
Anvol HFC for granite-quarry hydraulic systems where dust ingress, heat, and the intermittent nature of quarry operation elevate fire risk. Karimnagar / Warangal granite-belt installations.
Anvol HFC for aluminium-smelter pot-tending hydraulics + casting-mould hydraulics. The molten-aluminium environment demands HFC water-glycol service.
Anvol HFC for coal-handling-plant conveyor-transfer hydraulics + stacker-reclaimer hydraulics. Coal dust + heat = fire risk profile that mandates HFC service in major coal-handling installations.

Common questions from maintenance + procurement buyers sourcing Castrol Anvol Fire-Resistant Fluids through Vasundhara Specialities.
For iron-foundry pour-deck hydraulics with line-of-sight to molten metal: Anvol HFC water-glycol is the standard specification. Water content provides direct fire-suppression in any leak event. ISO VG 46 typical. NBR/Buna-N seal compatibility (most foundry-OEM hydraulic systems use these), no seal-changeover required from mineral. Lower cost than Anvol PE phosphate ester.
Anvol PE phosphate ester HFDR is preferred when: (1) very high system pressure (300+ bar) requires superior anti-wear performance, (2) servo / proportional valve precision is critical (HFC water-glycol may exhibit some valve-stickiness), (3) operating temperatures consistently above 60°C (HFC water-glycol water-loss accelerates above 60°C). Anvol HFC is preferred when: (1) line-of-sight to molten metal demands the highest fire class, (2) cost is a primary concern, (3) NBR/Buna-N seals are present (HFC compatible, PE incompatible).
NO — Anvol PE phosphate ester is INCOMPATIBLE with NBR/Buna-N seals. Phosphate ester chemistry causes NBR seal swelling, embrittlement and eventual failure within 6-12 months. Before changing over from mineral hydraulic oil to Anvol PE, the entire hydraulic system must be reviewed for seal compatibility — typically requires changeover to FKM/Viton seals throughout. This is a major commitment. For NBR-sealed systems, Anvol HFC water-glycol is the appropriate fire-resistant alternative (HFC is NBR-compatible).
Anvol HFC water-glycol: maximum bulk-fluid operating temperature 60°C continuous, 65°C short-term. Above 60°C, water content evaporation accelerates — requires regular water-content monitoring and top-up of fresh water (or replacement). For service consistently above 60°C (e.g. continuous-duty steel-mill stand hydraulics where heat soak elevates oil temperature), Anvol PE phosphate ester is the appropriate choice (rated to 90-100°C continuous).
Anvol HFC water-content drifts through evaporation (especially at temperatures >50°C) and through breathing of the reservoir. Maintenance protocol: monthly water-content sample analysis (target 35-45% water by mass), top-up with deionised water to maintain target, replace bulk fluid every 12-18 months in continuous service. Vasundhara Specialities supports periodic water-content monitoring + top-up service as part of the supply relationship.
Yes. Castrol Anvol PE meets FM Global Class 1 fire-resistant hydraulic fluid specification, plus ISO 12922 HFDR, 7th Luxembourg Report fire-resistance test, and major industrial-OEM specifications. Per-batch test certificates and FM Global cross-reference available on enquiry. For insurance-driven fire-protection requirements (FM Global, Factory Mutual, AIG-style industrial property insurance), the FM-approved Anvol PE specification is typically what is required.
