Product Description
Coomcool HYD HV 22 is based on a carefully selected ashless (zinc free) additive system designed to meet and exceed the most exacting performance standards.
Advantages
- High viscosity index and low pour point enables the product to be used over a wide temperature range. 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 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.
Applications
Coomcool HYD HV 22 is used for outdoor equipment operating in a wide range of temperatures, such as machinery requiring cold start and continuous operation at high temperatures, off-highway machinery and marine applications.
For indoor manufacturing equipment where built-in control systems require minimal temperature-dependent viscosity changes, such as precision machine tools.
