​ABOUT NATURAL ESTER FLUID

Natural ester 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, potentially saving you money in several ways:

  • Lower total life cycle costs due to extended insulation paper thermal life
  • Delayed asset replacement because natural ester 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 a 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 retrofills, SPX Transformer Solutions has the equipment, experience and capability to complete repairs and upgrades you may elect to perform while your transformer is drained of oil, such as transformer dryouts, regasketing or bushing replacements; combining services can minimize costs and transformer downtime.
