Lubricant varnish potential testing (Membrane Patch Colorimetry, MPC, ASTM D7843) is an essential part of turbine and compressor lubricant management. MPC testing identifies the propensity of a lubricant to form solid deposits so that maintenance professionals can avoid catastrophic failures.
While most customers are able to take advantage of our complimentary initial oil assessment or SVR™ system monitoring, remote sites may require on-site MPC testing or commercial oil labs may wish to add it to their existing oil analysis package. For this purpose, EPT’s MPC test kits comprise everything needed from a basic laboratory set up to a robust field kit designed for travel.
All users of our test kits are supported by a world-class team of chemists that perform 100s of MPC tests each month. Need answers? You will have access to the experts that will provide SOPs, training videos, and calibration standards.
Our video provides an overview of the MPC test, and the equipment and accessories required to complete it.
Our soluble varnish removal (SVR™) system targets and eliminates the cause of varnish formation – oxidation breakdown products – even during turbine operation when they are dissolved in the lubricant.
Our Non-Spark Discharge (NSD™) filters suppress filter sparking by significantly reducing friction. This eliminates the related high-temperature fluid breakdown protecting antioxidants and base oil.
Our customers receive verification of results through our lab. For remote sites, we also offer Membrane Patch Colorimetry (MPC) test kits for on-site varnish potential testing.
