B BBAAC

Performance Rating

  • Summary - Rating: BSuitable for central heating & LTHW systems where low toxicity is preferred. Average efficiency but higher cost compared with Thermaflow VT3 fluid.

  • Efficiency - Rating: CAverage thermal conductivity and higher viscosity at sub-zero temperatures, results in reduced heat transfer efficiency and increased energy demands, compared with Thermaflow DTX. Good Specific Heat capacity helps improve overall performance.

  • Antifreeze - Rating: BProvides protection down to -50°C but greater concentration (% volume) is required to achieve the same freeze-point protection, compared with Thermaflow DTX and CMF.

  • Corrosion Control - Rating: ALong-Life high temperature rated formulation with synergistic corrosion inhibitors to exceed ASTM D1384 standards. Also contains broad-spectrum biological inhibitors and polyacrylates to prevent scale precipitation.

  • Toxicity - Rating: AClassified as Non-Toxic and Food-Safe. Suitable for systems where low-toxicity is stipulated. LD50 Oral Rat >20,000mg/kg body weight.

Physical Properties

  • Density:1.02 - 1.15 g/cm³ depending on inhibitors

  • pH:7.5 - 9.0 depending on inhibitors

  • Boiling Point:>100°C

  • Characteristics:a clear, slightly viscous liquid. It is mildly sweet to the taste and has a non-pungent but characteristic aroma.

  • Available in: 5, 10, 20, 25, 205 & 1000 litre containers and bulk tankers.

Mixing Guide

When measuring the percentage concentration of Thermaflow TPF in solution we recommend the use of a recently calibrated refractometer.
