Univis™ N-C

Premium All Season Hydraulic Fluid

Product Description

UNIform VIScosity; is an essential characteristic for All Season hydraulic fluids. Modern high performance hydraulic systems rely on fluids that can resist changes in viscosity, as operating temperatures rise and fall. This is particularly important for outdoor hydraulic systems on stationary and mobile equipment that operate in climates where ambient temperatures can vary widely. The excellent All Season performance capabilities of UNIVIS™ N-C can help equipment operators to standardize to one viscosity grade for year round service in their outdoor hydraulic equipment.

UNIVIS N-C is available in five ISO VG viscosity grades, thereby providing a product designed to protect equipment over the wide range of ambient cooperating conditions in Canada. All grades are fully compatible and can be mixed in any ratio to suit ambient conditions.


Features and Benefits

Univis N-C is formulated with carefully selected base oils and a proprietary additive system, designed to provide well balanced performance in mobile and industrial equipment. These properties can help to provide long oil life and minimized deposit formation in hydraulic systems operating in severe conditions, at high pressure and temperatures. Shear stable viscosity modifiers provide higher viscosity indexes (VI). The higher the VI, the less effect temperature has on fluid viscosity. All Univis grades are formulated with enhanced VI properties that enable equipment to maintain maximum hydraulic efficiency and component protection over a wider temperature range. Outstanding foam control and air release properties provide protection for hydraulic systems by helping to prevent cavitation damage and micro dieseling.

FeaturesAdvantages and Potential Benefits
Stable, high-performance anti-wear additivesHelps reduce wear and protects pumps and components and extend equipment life
Excellent rust and oxidation controlOil-wetted parts, ferrous and non-ferrous, are provided with enhanced protection from rust, corrosion and the effects of oxidation
High VI, optimized low temperature fluidity, low pour pointsOptimized viscosity provides stable and uniform functioning of the hydraulic system over a wider temperature range than standard hydraulic oils
Excellent shear stability for stay in grade performanceEnhanced to help provide the required oil film to protect parts, over a long service life.
Rapid air release and powerful foam controlHelp to prevent destructive cavitation, aeration and resulting heat, and extend oil life
Good hydrolytic stabilityDesigned to resist the decomposition reaction caused by water, that can lead to the formation of acidic and corrosive materials
Rapid Demulsification of waterHelp to prevent corrosion, maintain viscosity control and extend equipment life
Good compatibility with elastomers and sealsLong seal life and reduced maintenance
