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.
