VARTECH® Industrial System Cleaner

VARTECH Industrial System Cleaner is designed to effectively remove varnish and sludge from lubricating systems in steam and combustion turbines, centrifugal and rotary screw compressors, and stationary hydraulic systems. It is recommended for use in ISO 22 to 100 viscosity grade fluids. VARTECH Industrial System Cleaner is accepted by Siemens Energy for use in steam and gas turbines, compressors, and generators to remove varnish and deposits.

The advanced cleaning chemistry effectively dissolves and disperses varnish surface deposits to minimize filter loading during cleaning compared to leading competitor cleaners. The solvent-free formula has low volatility and excellent compatibility with most elastomer seals.

For most effective cleaning results, VARTECH Industrial System Cleaner treatment should be added to the inservice fluid and circulated in normal system operation for a period of 7 to 30 days**. Operating temperatures in the range of 50 to 120°C are ideal for high cleaning performance. Lower temperatures may reduce cleaning effectiveness and need longer cleaning times.

¹ Extended times beyond times listed above are possible. Contact your Texaco representative for additional guidance and information.

² Lower operating temperatures generally benefit from longer circulation times.

* May not be compatible with some non-mineral based synthetic fluids.

** Extended times beyond times listed above are possible.

• Helps remove varnish and sludge, helping restore system efficiency with minimal flushing.
• Designed to help reduce equipment failure by clearing deposits that can accelerate component wear.
• Formulated to restore system performance by improving operation response in servos and small passages.
• Promotes heat transfer and full load operations by removing surface varnish.
• Helps decrease filter plugging and reduce the need for frequent filter changes during cleaning.
• Solvent-free formulation designed to ensure improved seal compatibility and reduced volatility.
  

VARTECH Industrial System Cleaner 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: 10% for severe varnish cleaning or 5% for maintenance service, or more if needed.

2. Install a fresh set of filters to maximize varnish and deposit collection. Ensure additional filters are available for the system as filter changes may be required due to release of varnish and deposits.

3. 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.

4. Add Chevron Vartech Industrial System Cleaner to the system, up to the chosen concentration, ideally while oil is circulating.

5. Operate the equipment as normal for the chosen duration. Ensure operating temperatures are maintained within the recommended range. Monitor filters for increased differential pressure; replace as necessary.

6. 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 as possible in the system where oil may get trapped (i.e. filter housings, coolers, piping, degassing tanks, etc.).

7. When possible, manually clean any accessible settled deposits and oil from the reservoir after draining.

8. System rinse* is recommended when any of the following exist:

a. Complete drain is not possible (more than 10% residual remaining) 

b. Extremely degraded in-service oil 

c. Severe deposits in the system

9. Replace filters.

10. Refill the system with a Chevron lubricant meeting equipment manufacturers’ requirement.

*Flush oil used should be compatible with the final fill oil.
