Heat Transfer Fluids

Petro Canada America and Houghton International

Heat transfer fluids (commonly known as HTFs) are extremely important lubricants to monitor and maintain. Upholding best practices through consistent Oil sampling and analysis as well as other predictive tools can prevent critical failures, reduce downtime and save on energy consumption. In high volume HTF systems with 800 gallons or more of contaminated fluid, consider Fluid Reclamation and save time, money and the environment.

Types of Heat Transfer Fluids

  • Mineral Oils – petroleum based, solvent refined fluids or severely hydrotreated/hydrocracked fluids
  • Synthetics – polyalphaolefins (PAOs) benzene derivatives (aromatics) and polyalkylene glycols (PAGs)
  • Food Grade –NSF HT1 registered

Indicators that your HTF is failing

  • High acid numbers
  • You have to turn up the heat
  • You have to increase the flow
  • The unit is using more power (be it gas or electric) then when it was new.


  • Plastics processing
  • Laminating
  • Solvent recovery
  • Cogen heat recovery
  • Wood products processing
  • Industrial laundry
  • Resins
  • Adhesives
  • Textiles
  • Composites
