Published Papers
ISOPur has had numerous papers published in magazines and presented all over the country. The following are summaries of recent technical papers.
Controlling varnish for longer-lasting oil and performance (May 2012)
Polk Power Station, Florida utilizes ISOPur’s BCA® technology and new oil chemistry to effectively control the varnish that was affecting servo valves.
MAINTENANCE-Addressing Varnish Problems (Jan/Feb 2012)
Balanced Charge Agglomeration® results in 50,000 hours of lube oil operation on GE Frame 7 Turbines.
New Methods for Trending Varnish in Mineral Turbine Oils (2007)
A paper presented at the 2007 NORIA Lubrication Excellence conference by Andy Sitton of Focus labs in Thailand, shows a correlation between Oil varnish reduction, the VPI test and RULER.
Andy shows a method for performing a VPI test that anyone could easily learn. He also offers this test to the world in a non-proprietary form.
ISOPur Rids Boiler Feed Pump of Sludge and Varnish (Jan/Feb 2005)
A case study authored by our very own Turkish rep, Teoman Kupeli with help from Trans Ticaret Company. The test was performed at EUAS Tuncbilek Thermal (coal) Power Plant located in Tuncbiliek, Turkey.
Oil analysis was performed and results are in the process of being translated. They are scheduled to be published in a follow-up article.
The Maintenance Challenge in Wind Power” (Dec 2004)
Gearbox failures account for the largest amount of lost production. Balanced Charge Agglomeration (BCA) is the seemingly deal answer to minimal maintenance of wind turbine gearboxes.
The maintenance of wind turbines is always a concern – not only because of their growing remote locations, but also the high cost and degree of difficulty in reaching the nacelle…
Small particulate removal key to long-term operation (May 2004)
Particulate contamination in industrial machine lubricants such as compressor oils and hydraulic fluids is an ongoing problem that threatens a machine’s ability to operate at optimal levels over a long time frame. The main problem is that particulates slowly and silently cause mechanical wear on the machinery. Coupled with water contamination, this process can lead to corrosion of metal surfaces and accelerate the oxidation of the lubricant.
It pays to keep lube oils super clean (Mar/Apr 2004)
Particulate contamination in turbomachinery lubricants is an ongoing problem that results in the less-than-optimal operation of equipment. The central issue here concerns small particulates that gradually cause mechanical wear.
The clearances between sliding surfaces in turbomachinery components are very small making even small contaminate a big problem.

Lubrication & Fluid Power: “The Journal of Machinery Monitoring, Standards and Solutions”
ISOPur solved valve varnish problem on Moog servo valves on low pressure hydraulic, Nuovo Pignone gas turbine fuel control. Using the lubrication sump with Mobil DTE Oil Light for the hydraulic controls is common in smaller gas turbines. Operating conditions can cause servo sticking and forced outages when fine particles combine to produce deposits.
Careful analysis of the lubricants in a wide range of installed units convinced the manufacturer’s engineering group that the removal of fine particulate was essential to continuous long-term high reliability operation. The proactive approach described below was evaluated as a strategy to eliminate potential problems before an unplanned outage occurred.
After observing the performance of an ISOPur unit on a turbine at a major US pharmaceutical company, the plant operator installed the units on all four steam turbines in the plant. This case study is based on the observed performance of the plant since that time, compared to the 15 years of operation before these systems were installed.
ISOPur eliminated the formation of coke and varnish by removing precursors from the oil. Three years later the turbine continues to operate at peak efficiency, with minimal system and or turbine maintenance. The ability of this kidney loop system to remove all particle sizes down to 0.1 micron, combined with the electronic scouring action which removes all sludge and varnish from the internals makes this an ideal component to maintain critical equipment in like new condition.
