Calflo* Heat Transfer Fluids

Calflo heat transfer fluids represent a family of advanced fluids for liquid phase applications between -40° F (-40°C) and 620° F (326° C) in both open and closed systems.

Calflo heat transfer fluids are available in four unique formulations of HT hydrocracked base oils and patented Petro-Canada additives that offer the thermal efficiency and cleanliness of paraffinic hydrocarbons with the high thermal stability of chemical aromatics.

Because Calflo heat transfer fluids are also non-toxic and odorless, it's no wonder manufacturers around the world rely on them in such a vast array of process heating applications.

  • Calflo HTF for high-temperature applications up to 620° F (326° C).
  • Calflo AF for superior oxidation resistance up to 600° F (316° C).
  • Calflo LT for heating and cooling applications from -40° F (-40° C) to 500° F (260° C).
  • Calflo FG for food grade applications up to 620° F (326° C).
