VARTECH® Industrial System Cleaner

VARTECH®ISC delivers value through: 

• The stabilization of varnish and sludge deposits into the oil to enable their efficient removal through a scheduled oil change, helping to restore system operational efficiency
• An advanced formulation to help decrease filter plugging
• Its excellent compatibility with many turbine and compressor products (mineral and synthetic hydrocarbon based)
• Helping retain both oil/water separability and enhancing oxidation life performance
• A solvent-free formulation designed to offer excellent seal compatibility
• Low volatility for effective cleaning times
  

When added to the end-of-life in-service oil, VARTECH®ISC’s state-of-the-art triple-action technology: 

• Helps cut through hard varnish to remove it as micro-sized varnish particles
• Captures and stabilizes the micro-sized varnish particles in a protective barrier to assist with removal of the varnish from the system without re-depositing to the equipment
• Provides compatibility with the in-service oil for optimum operational flexibility while helping to maintain system performance during the cleaning cycle to prepare for change out to fresh oil

VARTECH® ISC is suitable for use in concentrations between 5% to 20% of the total oil volume in the system. It is designed to be effective under normal operating temperatures, not to exceed 120°C (250°F).

VARTECH® Industrial System Cleaner is added directly to the in-service lubricating oil. If the current oil is severely deteriorated, best practice is draining the degraded oil and refilling with fresh oil so the cleaner can be added to a new fill of oil meeting the OEM’s specifications.

1. Determine the amount of cleaner required and the cleaning duration (refer to Table)
2. Install a fresh set of filters to maximize varnish and deposit collection.
3. Ensure additional filters are available as filter changes may be required due to the release of varnish and other deposits.
4. If needed, drain an adequate volume of in-service oil to ensure maximum fill levels are not exceeded when adding the system cleaner.
5. Add VARTECH® ISC to the system up to the selected treat rate, ideally while the oil is circulating.
6. Operate the equipment as normal for the selected duration and monitor filters for increased differential pressure. Replace blocked filters as required.
7. Drain the oil-cleaner mixture from the system while it is still warm and recently circulated. Ensure safe handling temperatures. When possible, drain locations in the system where oil may be trapped, e.g., filter housings, coolers, piping, de-gassing tanks, etc.
8. When possible, manually clean any accessible settled deposits and residual oil/cleaner mixture from the reservoir.
9. Industry best practice recommends a system rinse*** when changing oil. A rinse is particularly important when any of the following conditions exist:
   
   • Prior to cleaning, the in-service oil was experiencing rapid oil degradation or was extremely degraded,
   • Prior to cleaning, there were severe deposits in the system,
   • More than 10% of the oil-cleaner mixture remains after draining.
10. Replace filters.
11. Refill the system with a product which meets the OEM’s specifications.
