Bartran™ HV high viscosity index (VI) lubricants are based on a carefully selected ashless additive system designed to meet and exceed the most exacting performance standards.
Application
Bartran HV oils are intended for severely stressed hydraulic systems requiring a high level of anti-wear performance and fine filtration. In addition, Bartran HV exhibits excellent corrosion protection as well as outstanding thermal and oxidative stability. Bartran HV has excellent hydrolytic stability and separates rapidly from water contamination. The selection of a shear stable VI Improver ensures that there is no excessive loss in viscosity due to mechanical shearing. The VI Improver also imparts a very low pour point which enables the product to be used in very cold environments.
These grades are intended for two main types of duty:
Outdoor machinery likely to operate in wide ranges of temperature - such as equipment subjected to cold start up conditions and high temperature continuous running. Examples include off-highway and marine applications.
Indoor manufacturing equipment that incorporates control systems requiring a hydraulic fluid whose viscosity change with temperature is minimal. Examples include precision machine tools.
The Bartran HV range is fully compatible with elastomer materials commonly used for static and dynamic seals, such as nitrile, silicone and fluorinated (e.g. Viton) polymers.
Advantages
High viscosity index and low pour point enables the product to be used over a wide temperature range, with good shear stability means no excessive loss in viscosity due to mechanical shearing.
Excellent anti-wear performance provides extended wear protection for hydraulic pumps. Reduced down time due to unscheduled maintenance and savings from reduced replacement part costs.
Excellent water separation and hydrolytic stability means reduced down time through prolonged lubricant life and increased equipment reliability.
Excellent thermal and oxidative stability provides reliable performance and extended oil life in severe applications.
Minimal deposit formation gives a cleaner system and reduced frequency of filter changes.
Good filterability characteristics in both wet and dry conditions enable cost savings to be made due to increased filter life.
