VARTECH(TM) Industrial System Cleaner (ISC)

Product review summary

Chevron VARTECH ISC delivers value through:

  • Stabilizes varnish and sludge surface deposits in the oil to enable their efficient removal through a scheduled oil change, restoring system operational efficiency
  • Being solvent free, reducing volatility and seal compatibility concerns
  • Minimal filter plugging
  • Excellent compatibility with many compressor and turbine oil products (mineral and synthetic hydrocarbon based)
  • Retains oxidation control performance
  • Excellent seal compatibility
  • Extended cleaning duration times are possible
  • Minimal flushing

Chevron VARTECH ISC is ideal 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).
INSTRUCTIONS FOR USE: Chevron VARTECH ISC is added directly to the in-service lubricating oil. If the current oil is severely deteriorated, it is recommended the degraded oil be drained, and the cleaner added to a new fill of recommended oil.
  1. Determine the amount of cleaner required and the proper duration (see chart in Product Data Sheet link above).
  2. Install a fresh set of filters to maximize varnish and deposit collection.
  3. Ensure additional filters are available for the system as filter changes may be required due to release of varnish and deposits.
  4. Ensure system does not exceed maximum fill levels when adding the system cleaner; if needed, drain adequate volume of oil to maintain proper operating volume.
  5. Add Chevron Vartech ISC to the system, up to the chosen concentration (by Vol %). Ideally while oil is circulating.
  6. Operate the equipment as normal for the chosen duration and monitor filters for increased differential pressure; replace as required.
  7. Drain the oil/cleaner mixture from the system while the oil is still warm (safe handling temperatures) and recently circulated. When possible, drain as many locations in the system where oil may get trapped (i.e. filter housings, coolers, piping, de-gassing tanks, etc.).
  8. When possible, manually clean any accessible settled deposits and oil from reservoir after drain.
  9. System rinse* is recommended when any of the following exist:
    • Complete drain is not possible (approx. < 10% remains)
    • Extremely degraded in-service oil
    • Severe deposits in the system
  10. Replace filters
  11. Refill the system with Chevron lubricant per OEM specifications.
