FR3™ Retrofills

Native American Transformer Services, Inc. was one of the first to embrace FR3™

Our equipment and American Philosophy are geared to provide dielectric fluid for almost any substation-size transformer within your grid.

NATS can advise on the suitability of a unit for retrofilling, suggest other alterations and repairs you may want us to make at the same time and take care of disposing of your non-PCB oil. NATS has several FR3™ fluid retrofills successfully completed, and we have the training, expertise, and knowledge to meet or exceed your environmental needs.

Envirotemp™ FR3™ fluid is a biodegradable dielectric coolant made from a formulation which includes vegetable oils and is proven to add value to new and retrofilled power equipment.

Envirotemp™ FR3™ retrofills possibly SAVES YOU MONEY in several ways:

LOWER TOTAL LIFE CYCLE COSTS

Due to extended insulation paper thermal life by a factor of 5-8 times (verified by Cooper Power Systems using IEEE standard tests).

DELAYED ASSET REPLACEMENT

Because FR3™ fluid-cooled transformers experience a slower aging rate of cellulose insulation compared to mineral oil-filled transformers.

LOWER PERSONNEL AND EQUIPMENT COSTS

Due to greater flexibility when selecting installation sites along with simplified fire safety and installation requirements.

LOWER INSURANCE AND LIABILITY COSTS

Due to greatly reduced risk of fire (dependent on insurance company policies).

LOWER CLEAN-UP COSTS

In the event of leakage (dependent on geographical regulations and other factors).

SLOWER INSULATION AGING DURING PERIODS OF OVERLOAD

If increased output, rather than longer equipment life, is a primary goal.

In addition to FR3™ Retrofills, NATS has the equipment, experience and capability to complete repairs, upgrades, insulation dryouts, bushing replacements, and LTC repairs/upgrades.
