UNIVIS™ HVI 13 and 26 have been formulated to provide outstanding viscosity control in applications where ambient temperature can vary widely, from very cold to warm. In addition to their wide operating range, these fluids provide excellent wear protection, potent rust and corrosion protection, rapid foam and air release and outstanding resistance to oxidation. These performance features help to provide the protection required to keep hydraulic systems operating more efficiently over a wide operating temperature range.

Features and Benefits
UNIVIS HVI 13 and 26 are designed to deliver the following features and potential benefits:
Features |
Advantages and Potential Benefits |
High Viscosity index – wide operating temperature range |
Outstanding fluidity for low temperature start-ups, improved viscosity protection for pump components operating at both at low and high temperatures |
Effective foam control and air release |
Rapid air release, which helps to protect components from cavitation, wear and excess heat |
Outstanding oxidation stability |
Helps keep components clean and free from sludges and varnishes that reduce hydraulic efficiency and operating life. Can help to extend oil life and reduce maintenance requirements |
Excellent protection against rust and corrosion |
Helps to improve component life and reduce failures associated with rust and corrosion damage to system components |
Potent Anti-Wear protection |
Components wear rates are reduced by anti-wear and this can lead to improved component life and reduced maintenance |
Applications
• Stationary and mobile hydraulic systems operating in a wide range of ambient temperatures and conditions, indoors and outdoors
• Systems where very reliable cold weather start-up is a critical requirement
• Operations where lubricant consolidation and simplification is required
