Natural Ester Fluid RFQ Intake

This form is built for electric utilities, industrial facility owners, EPCs, and transformer service contractors sourcing natural ester dielectric fluid for new fills, retrofills, and replacement supply.

  • Product type — new fill, retrofill, top-up, or replacement supply
  • Transformer voltage class, MVA/kVA rating, and cooling class
  • Fluid specifications — fire point, pour point, biodegradability
  • Retrofill conversion scope and applicable standards

For New Transformer Fills

Specify voltage class, MVA/kVA rating, cooling class, and required fire point classification for a new transformer built to ship filled with natural ester fluid.

For Retrofill and Conversion Projects

Capture existing fluid type, transformer age and condition, gasket compatibility, and degassing/drying scope needed to convert an in-service unit to natural ester.

For Fluid Supply Only

Provide quantity, packaging, delivery timeline, and applicable standards for a straight fluid supply order with no field service required.
