Tests show that Clean Oil Services Pty Ltd standard Lubemaster OS600 Oil Filtration Unit is fast becoming established as an invaluable Lubrication Management tool with many units being sold both locally and overseas with larger clients returning to buy more units once they have become familiar with the machines and completed their cost & performance justifications.

Recently Clean Oil Services experienced  success in the power transformer oil cleaning market when a client ran trials with its standard Lubemaster OS600 Oil Filtration unit and obtained independent laboratory analysis of the test results.   

Approximately 200Lt of waste Shell Diala M transformer oil was decanted into the Lubemaster tank and filtered for approx. 8 hours with a sample being collected before and after filtering.

The results say it all:  

  • water Saturation was 68% - reduced to 20%
  • dielectric Strength increased from 5kv to 60kv; and
  • particle Contamination reduced by over 45%.
The particulate residue caught in the rotor housing was also quite considerable. These encouraging results led Clean Oil Services Pty Ltd to conduct a further trial on a 205 ltr drum of discarded transformer oil ran in conjunction with its Fullers Earth filter unit.

The result was a complete renewal of a product which was going to be discarded:

  • Dielectric Strength rose to 75 kv
  • TAN decreased to 0.01 mgKOH/gm
  • particles reduced substantially with all particles below 1um
  • water reduced to below 12ppm; and
  • colour returned to a light, completely transparent amber.
These results come at a fraction of the cost of conventional dehydration methods with the vacuum dehydration not only removing the water but degassing the oil in the process.    

Lubemaster offers a viable alternative to cleaning and de-gassing transformer oil at a fraction of the cost of the traditional bulky units we have become familiar with.
