B BBAAC

Performance Rating

  • Summary - Rating: BSuitable for central heating and LTHW systems where low environmental impact and ecological sustainability is preferred. Average efficiency but lower in cost compared with MPG based fluids.

  • Efficiency - Rating: CAverage thermal conductivity and high viscosity at sub-zero temperatures, results in lower heat transfer efficiency and increased energy demands when compared with Thermaflow DTX and CMF.

  • Antifreeze - Rating: BProvides protection down to -50°C but more 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 - 1.26 g/cm³

  • pH:7.5 - 9.0 depending on inhibitors

  • Boiling Point:>100°C

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

  • Available in: 5, 10, 15, 20, 25, 205 & 1000 litre containers and bulk tankers.

Mixing Guide

When measuring the percentage concentration of Thermaflow VT3 in solution we recommend the use of a recently calibrated refractometer.
