Oil Services


Emerald Transformer’s cradle-to-grave approach includes the proper handling and processing of mineral oil when equipment is repaired or decommissioned.

Emerald Transformer recycles millions of gallons of dielectric oil each year. We have the resources and expertise to fully recycle oil that comes from the equipment we service, or oil brought in from the field using our large fleet of tanker trucks.

Oil received with PCB levels above 1 part per million will go through our PCB removal process before the oil continues through the re-refining process. Our oil is filtered, degassed, and dewatered to return it to a proper specification. In-line testing equipment allows our personnel to closely monitor the purification process to ensure that the oil reaches our quality standards. Once the oil recycling process is complete, an additional sample is taken, and an outside testing laboratory tests and certifies that the oil is ready to be reintroduced as either a dielectric fluid or for use in other base oil applications.

I would like to thank Emerald for your assistance with the recent equipment recycling effort... We have disposed of three power transformers and thousands of gallons of oil...I also want to express my appreciation for your field service crew. The crew has been on property the last two weeks removing transformers from substations. The work was completed in a safe, timely and professional manner. Your crews have been on property for prior recycling efforts and I am always pleased with their efforts. I look forward to working with you to remove the remainder of the equipment by the end of the year.
