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.

Contact Emerald Transformer today to talk about creating an environmentally-conscious solution for your oil recycling needs.

"I am very pleased with the Emerald crew that worked with us last week, and was able to hit my March 1 removal goal very easily by using Emerald's services at 3 different substations. I prefer the Emerald staff to work with – due to crew workmanship, our relationship and the ease of doing business."
