HYDRATEC HVI 46 - Hydraulic Oil
Aztec oils Hydratec HVI 46 is a high-viscosity-index, mineral-based hydraulic fluid designed for demanding hydraulic systems that operate across wide temperature ranges and high pressures.
Engineered with a blend of solvent-refined base oils and viscosity-index improvers, it delivers stable performance, superior protection and efficient, reliable operation for machinery exposed to variable conditions.
Recommended Applications
- Hydraulic systems with vane, piston, or gear pumps operating under high pressure
- Industrial machinery requiring consistent oil viscosity in both warm and cold environments
- Mobile equipment (e.g. construction, lifting) with variable temperature exposure
- Systems demanding wear protection and long-term stability, such as power packs and hydraulic power units
- Application where fluid emulsification is a concern - ideal where good water-separation is required
- Suitable for: Denison HF-0, HF-1, HF-2 DIN 51524 Part III HVLP ISO 11158 Type HV ISO 6743-4 Type HV
Key Benefits
- Exceptional Temperature Stability - thanks to its high viscosity index, this oil maintains a more consistent viscosity in hot and cold conditions
- Outstanding anti-Wear Protection - robust additive system protects pumps, valves and motors under severe load
- Excellent Oxidation Resistance - helps prevent gum and lacquer formation, extending fluid life
- Good Demulsification and Water Separation - minimises emulsions, reducing risk of damage from water contamination
- Low Foam & Fast Air Release - ensures stable performance under dynamic hydraulic conditions
- Energy Efficiency - high VI and stable viscosity contribute to reduce drag losses and smoother system operation
