INTRODUCTION

Regen Oil is a relatively new company; however we have the combined experience of Fifty years in the treatment of Transformer and Hydraulic Oils.

We recently purchased additional Transformer Oil purification equipment to add to our “state of the art” Hydraulic Oil purification and Transformer regeneration equipment.

With the acquisition of the Transformer Oil purification equipment, key personnel joined Regen Oil. In addition to their own experience, Fluidex SA, a leading manufacturer of Oil purification and regeneration plants, has also trained them.

We currently carry out purification for many clients; should you require specific names and contact details we would be happy to provide these.

A few notables are;

  • Botswana Power
  • Eskom
  • Tanesco (Tanzanian Electricity Supply co)
  • Bindura Nickel (Now a new name)
  • Zambia Sugar (Illovo)
  • Mittal
  • Anglo
  • Rio Tinto
  • Zimalloys   

TESTING

We use independent Laboratories for the testing of Oils, as we feel there would be a conflict of interest if testing were carried out in-house. We can take samples and have them analysed.

We recommend that all Transformer Oil be tested for PCB contamination. These samples can be taken by our Staff and would be sent to appropriate labs for analysis.


TRANSFORMER OIL PURIFICATION

Oil purification forms an important part of regular preventative maintenance. In the process of purification, water, dirt and gasses are removed from the Oil.

Dielectric Strength: Improvement of dielectric strength of up to 70kV with new oil.
Water Removal: From 50 PPM down to 5 PPM in a single pass and to 3 PPM in two passes.

Gas Removal:  From fully saturated with air (10 to 12% by volume) down to less than 0.1%.
Particle Removal: 98% of particles over 0.5 microns.

We recommend that this be carried out at least every 12 months.


TRANSFORMER OIL REGENERATION

When the oil in a transformer reaches a stage (due to ageing) where purification and degassing is no longer efficient, the oil must be changed or regenerated. Regeneration is the complete treatment of oil back to a “like new condition”.

Why is Regeneration necessary?

As oil ages in a transformer it oxidises and begins to break down. Some of the by-products of this degradation are:

  • Acids
  • Aldehydes
  • Peroxides 

These bind together and form sludge. The sludge attacks the chemical bond, which holds the cellulose insulation together (measured by polymerisation).

When the oils neutralisation number is as low as 0.05, the cellulose insulation is already beginning to weaken. Since the cellulose insulation can only be replaced with a rewind, and the resultant loss of production, it makes sense to remove the oxidation by-products before they damage the cellulose.

Since any degradation of the cellulose that occurs cannot be reversed, it is best to remove the oxidation by-products on a regular basis.

The life of the transformer is the life of the cellulose insulation.

Only oil Regeneration methods are capable of removing the sludge found in ageing transformer oil and in the cellulose insulation of the transformer.


HYDRAULIC OIL PURIFICATION

Why is Purification necessary?

The single greatest enemy of any hydraulic system is the ingress of impurities into the system.

  • Dirt
  • Water
  • Meta Particles 

In built filtration systems merely reduce the risks whereas purification eliminates them.

How is purification carried out?

Using Regen Oil’s Fluidex IP 600 Plant. The plant is the result of years of intensive research and is used in the U.S.A., Europe, and the Pacific Rim countries.

Results of ISO 11/9 have been achieved with water content of 0%. We normally strive to achieve 17/14 or better with water less than 0.2 %

Can purification be carried out on line?

Purification can be carried out On Line; there is no need to shut the plant down. Purification can also be carried out Off Line; the plant is shut down completely. This allows for complete drainage of the Oil, opening and cleaning of the Sumps where possible.

When should purification be carried out?

We recommend that your Oil be purified bi-annually, once On Line, and once Off Line.

Should the Oil be tested?

Yes, independent Laboratories can carry this out. Your individual requirements and the operating environment govern the frequency of testing.

What are the cost savings in purifying the Oil?

Substantial savings can be achieved in the following areas:

  • Down time: Drastically reduced due to Oil condition monitoring and maintenance.
  • System Maintenance: Drastically reduced due to the reduction of wear and friction on all moving components, i.e. Pumps, Valves and Cylinders.
  • Costs: Large savings in System costs can be achieved in the following areas:
    Life span of Hydraulic Oil should be indefinite; carrying out purification alleviates the necessity to purchase new oil and costs approximately 30 – 35% the cost of new Oil.
    The life span of Pumps, Valves and Cylinders is increased dramatically.

Proactive Oil Maintenance and Analysis Diagnetics

  • According to the bearings division of TRW – “Contamination is the number one cause of bearing damage that leads to premature removal”
  • Machine Design Magazine reports – “Less than 10% of all rolling element bearings reach fatigue limit because contamination usually causes wear or spalling failure far earlier.
  • Caterpillar advises – “Dirt and contamination are by far the number one cause of hydraulic system failures.” 
  • J. I. Case state that – “One thing holds true about hydraulic systems; the systems must be kept clean ~ spotlessly clean ~ in order to achieve the productivity they are capable of.”
  • Proactive studies by the U.S. Navy show that the cost of contamination on marine and aviation equipment per operating hour exceeds 60% of the cost of fuel per hour on the same equipment.
  • M.I.T. report that – “Six to seven percent of the gross national product (US $ 240 billion) is required just to repair damage caused by mechanical wear; wear is the result of contamination.”
  • Oklahoma State University reports – “ When fluid is maintained ten times cleaner, hydraulic pump life can be extended by fifty times”
