Advantages
- Convenience of operation. The unit is quickly connected to tanks for clean and dirty oil through camlock quick couplings; the oil purification process is visually monitored by means of sight glasses; a service hatch is provided at the bottom of the columns for their maintenance and cleaning.
- The unit can operate in automatic mode. The required operating mode is selected, and the actuators are controlled from the touch panel which displays a mnemonic diagram of the unit. In order to enable the control buttons, the operator just needs to touch them.
- The adsorbent is reclaimed without being removed from the unit and can be used for the next regeneration cycle immediately after cooling. At the end of the last reactivation, the adsorbent can be used as a construction aggregate or in agriculture to loosen compact soils.
- There occur no harmful emissions into the environment during the unit operation. The unit is equipped with a two-stage system for neutralization of combustion products which consists of a carbon filter and a catalytic converter.
The CMM-6RL unit is designed for transformer oil regeneration.
The regeneration process involves passing the oil through six columns, each containing 75 kilograms of Fuller’s earth adsorbent — a substance with a microporous structure. All harmful impurities and aging products are captured in the adsorbent granules. The cloudy, brown oil becomes clean and clear. Breakdown voltage increases, acid number decreases, and the dielectric loss tangent drops. Thanks to regeneration, the used oil regains the properties of new oil and can be reused in the transformer for insulation and heat removal.
Once the regeneration quality no longer meets the requirements, the unit can be switched to sorbent reactivation mode. The sorbent is reclaimed by burning and then used again for transformer oil regeneration.
