Transformer Oil Purification & Regeneration
CMM-6RL Transformer Oil Regeneration Unit
CMM-6RL unit is designed for regeneration of transformer oils.
The regeneration process is about running the oil through six columns each of
which contains 75 kilograms of Fuller’s earth
adsorbent – a substance with a microporous structure. Furthermore, all harmful
impurities and aging products are retained in the adsorbent granules. The turbid
and brown oil becomes clean and clear. The breakdown voltage increases, the
acidity number and the dielectric loss tangent decrease. Owing to regeneration,
used oil regains its properties to the level of new oil and is reused in a transfor
mer for insulation and heat removal.
As soon as the oil regeneration quality ceases to meet the requirements, the unit can
be switched to the sorbent reactivation mode. The sorbent is reclaimed by
burning and subsequently used again for transformer oil regeneration.
CMM-8LT Oil Processing Unit
The vacuum oil unit CMM-BLT is designed for purification from mechanical im
purities and water of electrical insulation oils, the kinematic viscosity of which
does not exceed 70 est at a temperature of 50° C.
The unit can be used for heating oil-filled electrical apparatuses with hot
transformer oil and for their vacuuming.
The station ensures oil purification up to class -/12/9 with an initial purity class of
-/16/13 (mass fraction of contaminants not exceeding 0.004%) with multiple
passes of the purified product through the filter block.
The station is used in the assembly, repair, and operation of oil-filled high-voltage
equipment (power transformers, high-voltage switches, etc.).
CMM-6LT Industrial Oil Purification Unit
The mobile oil station CMM-6LT is designed for thermovacuum drying, filtration,
and purification from mechanical impurities and water of oils used in lubrication
systems, sealing systems, hydraulic control systems of gas turbine and gas compressor
units, gas-motor-compressors, as well as transformers, during operation
and maintenance.
The unit can be used for cleaning contaminated oils from water, free and dissolved
gases, heating and drying oil-filled electrical apparatuses with hot transformer oil,
using the thermovacuum drying method. Additionally, it can remove mechanical impurities
through high-efficiency filter elements. The unit is applied in assembly,
repair, and operational organizations engaged in oil processing and purification.
