Thermaflow ThermaflowCentral Heating Fluids

A range of heat transfer fluids with antifreeze function, for use in central heating and LTHW systems, both commercial and domestic.

To prevent internal corrosion, scaling and biological fouling all Thermaflow products are formulated with long-life inhibitors which exceed ASTM D1384 standards.

Launched in 2010 Thermaflow DTX represents a major step forward in heat transfer and pumping efficiency, providing >10% increase in heat transfer when compared with Propylene Glycol based fluids.

  • Summary - Rating: ASuitable for central heating & LTHW systems and other heating applications where a non-toxic classification is preferred. High efficiency and more cost effective than MPG and much less toxic than MEG.

  • Efficiency - Rating: BHigh thermal conductivity and low viscosity at sub-zero temperatures, results in increased heat transfer efficiency and increased heat recovery.

  • Antifreeze - Rating: AProvides protection down to -50°C and less volume is required to achieve the same freeze-point protection, when compared with MPG based fluids.

  • 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 or preferred.

  • Density:1.04 - 1.15 g/cm3

  • 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, 15, 20, 25, 205 & 1000 litre containers and bulk tankers.

Thermaflow TPF Thermaflow TPF

B BCBAA

Non Toxic Heat Transfer Fluid with Antifreeze for use in Hot Water Heating Systems. Based on Propylene Glycol and ASTM D1384 High Temperature Rated Corrosion, Scale & Biological Inhibitors.

Show more...

  • 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.

  • 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, 15, 20, 25, 205 & 1000 litre containers and bulk tankers.
