KONDIC Oil Filtration

Proper transformer oil conditioning has become an important factor in production, commissioning, repair and
overhaul of transformers.

The transformer oil electric properties resp., it's puncture strenght, insulating resistivity and loss coefficient, depend
considerably on the moisture and gas content in the insulating oil.

The oxygen conent has influence on the aging process resp., on oxidation, which results in an increased loss
coefficient and in deposit formation.

The majority of transformer's breakdowns and downtimes are caused by bad oil condition.

“KONDIC” Company is involved in the production of several types of machines, which perform the following
operations:

- oil drying (separation of free and dissolved water),
- separation of gases from oil, and
- oil filtering for separation of impurities, fibres and metal particles.

Our Units transformer oil treatment plant, depending of their
type, are cheaper up to 50% of foreign producers, thereby excluding any transportation
costs, duties and other cost.

All essential parts of the Unit (vacuum pump, gear pump, electromagnetic valve and floater) are produced by leading
German manufacturers.

Some of the components (such as fine and coarse filters, temperature control, construction of the heaters, gear
pump) had to be modified to improve the operation of the Unit and to eliminate shortcomings noticed in the operation
of some other machines of this kind.

Decontamination of PCB contaminated equipment is performed on‐site using Institute Nikola Tesla patented
technology („Process for simulatenous removal of polychlorinated byphenyls, anticorrosive desulphurization and
regeneration of mineral insulating oils“).
