Vartector Varnish Potential Analyzer

Varnish Potential Evaluation System By MPC (Membrane Patch Colorimetry)

  1. General Details

    Vartector Varnish Potential Analyzer detects the risk of turbine oil varnish ASTM D7843 (Standard Test Method for Measurement of Lubricant Generated Insoluble Color Bodies in In-Service Turbine Oils using Membrane Patch Colorimetry).

    Potential hazards of turbine oil varnish indicates problems such as turbine bearing vibration and temperature increase, filter clogging, poor temperature control, turbine oil degradation may occur.

    Varnish Potential Analyzer diagnoses the potential hazards of varnish and soot in the machinery oil. Device detects CIE delta L value and a and b values as optical colorimetric notation. It is possible to diagnose if the thermal load is created by soot or varnish. Both soot and varnish amounts are measured with risk levels to the machinery . When CIE delta L value is high, it means an increase in soot level and that shows bubbling problem in the system and problem in pump cavitation. If a and b values are high, it means a risk of varnish formation.
