Transformer
oil regeneration, a process whereby acid,
sludge, oxidation by-products etc are
removed, has been in the market for more
than 30 years. This conventional system
is nowadays called the dumping-type. This
is due to the fact that the clay i.e Fuller's
Earth, is used only once and then disposed together with oil and contaminants trapped inside it.
This conventional system is now being
phased out in developed countries as it
creates environmentally hazardous waste. Hence, manufacturers
of this old technology are currently focussing
on the markets in the developing and third
world countries where environmental control
is still lax.
TXM on the other hand has been utilizing the NEW REGENERATION TECHNOLOGY, whereby the Fuller’s Earth is permanently installed in the regeneration plant. When the Fuller’s Earth is no longer effective in adsorption of contaminants, it is then self-reactivated within the regeneration plant. After its reactivation, regeneration of oil will continue and the process is therefore environmentally friendly. The Fuller’s Earth is utilized up to 300 times until it is no longer efficient to remove contaminants from the oil. In addition, the used Fuller’s Earth is non-hazardous and could be disposed off safely as normal clay.
The
major differences in TXM's technology
and the conventional system is tabulated

oil regeneration has more benefits in
comparison with replacing the oil in the
transformer or filtering the oil. Firstly,
by doing it live, from the consumer's
perspective, they will not face any load
shedding or supply disruption.
Secondly,
from the transformer's perspective, apart
from reclaiming or regenerating the oil
to its original condition, the transformer
is also removed of sludges and other impurities
from its windings. This is possible as
the oil is circulated a number of times
through the transformer and the process
is only stopped when the oil condition
at the bottom of the transformer has reached
the acceptable condition and the transformer
is rid of sludge, moisture and impurities.
