On 15 November 2015, in the city of El Paso, Texas, USA, GlobeCore employees completed the commissioning and start-up of a new GlobeCore CMM-12R oil regeneration unit.
This CMM-12R unit is designed for the complete regeneration of dielectric transformer insulating oil by removing moisture, contaminants and dangerous acids.
The GlobeCore CMM-12R unit processes insulating oil by directly hooking up to the power transformer and has a flow rate capacity up to 4 m3/1059 gals. per hour. The CMM-12R can process oil on an energized transformer, or with the transformer offline.
The CMM-R12 is able to perform oil regeneration operations on site. The unit will remove water, moisture, and contamination from the windings and solid insulation utilizing a Fuller’s Earth renewable sorbent. The sorbent itself can be reactivated many times eliminating the need to stop the regeneration process to unload and reload sorbent. Use of the GlobeCore Process regeneration technology can extend the service life of the electric power transformer up to 20 years and beyond.
