Caltex VARTECH® ISC removed high build-up of varnish in Chevron Thailand’s offshore CPP compressor, improving heat transfer, reducing contaminants, and preventing costly downtime.
Caltex VARTECH® ISC removed high build-up of varnish in Chevron Thailand’s offshore CPP compressor, improving heat transfer, reducing contaminants, and preventing costly downtime.
VARTECH® ISC successfully removed the build-up of varnish, restoring system cleanliness and improving operational efficiency without disrupting offshore platform performance.
After implementing VARTECH® ISC, insoluble MPC levels dropped from 71 to 27 (∆E), demonstrating the product's effectiveness in solubilizing the varnish present.
After implementing VARTECH® ISC, temperatures improved almost immediately, resulting in improved heat transfer across the bearing and lowering the overall temperature by 15°F (~9°C), with no further spikes reported after application.

The offshore CPP experienced an unusual spike in temperature to the thrust bearing of the power turbine unit due to heavy varnish build-up in the compressor oil, risking costly downtime and loss of operational efficiency.
Caltex recommended VARTECH® Industrial System Cleaner (ISC) to remove varnish build-up, followed by switching to GST Advantage® RO 32 with VARTECH® Technology and implementing LubeWatch monitoring.
