Compact and easy to use. Units processing range from 260 to 4,000 gals per hour (1,000 to 15,000 liters per hour)

Oil Regeneration Rigs (CMM-R)

Removal of acids and other products of oxidation.  Improving of oil color along with oxidation stability and gas solubility.
Reactivatable Adsorption Columns ranging from two (2) to thirty-two (32) in design with process cababilities up to 2,700 GPH (10,000 LPH)

Oil Filtration Rigs (CMM)

Removal of water (free, emulsified and dissolved) and particulate matter from insulating, hydraulic, gear and lubricating oils. Units processing range from 160 to 2600 gals per hour (600 to 10 000 liters per hour)

Acid number

Acidity reduction from 0.28 mg·KOH/g to 0.01 mg·KOH/g as per ASTM method D-664.

Unused mineral insulating oil should be neutral and free from any acidic compound.

Oxidation of oil gives rise to acidity and sludge formation and can be minimized as a result of high oxidation stability leading to longer service life time by minimizing sludge deposition, electrical losses, metal corrosion, electrical faults and maximizing insulation life.

Gas Levels

Gas Removal: From fully saturated with air (10 to 12% by volume) down to less than 0.1% by volume as per ASTM Method D-2945.

The dissolved gasses can cause a catastrophic failure of the transformer.

The total of all combustible gases may indicate the existence of any one or a combination of thermal, electrical, or corona faults.

As a result, if gasses value exceeds the limits, removal of transformer from service should be considered.

Dielectric strength

Improvement in dielectric strength up to 75 kV.

The oil shall have a high dielectric strength of minimum 70 kV breakdown voltage.

Breakdown voltage of transformer oil indicates its ability to resist electrical stress in electrical equipment.

Oil color

Improvement of color from 5 to 0.5 units as per ASTM method D-1500 and DIN 51578, ISO 2049.

As the oil ages and oxidizes, it gets darker.

Contamination may also cause a rapid change in color.

“Bad” oil can be colored. Anything other than “clear and bright” is unacceptable.

Moisture level

Water removal from 50 ppm down to less than 5 ppm as per ASTM method D-1533.

Moisture raises the risk of dielectric failure in the equipment.

A low water content of mineral insulating oil is necessary to achieve adequate electrical strength and low dissipation losses.

In order to optimize transformer life, you should maintain your insulation less than 0.5% M/DW (moisture by dry weight).
