Thermox Thermox Geothermal Fluids for GSHP Systems

A range of fully inhibited geothermal fluids, with antifreeze function, for Ground Source Heat Pump and Geothermal systems. Thermox solutions are installed in GSHP systems of all sizes throughout the UK.

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

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

  • Summary - Rating: ASuitable for geothermal, GSHP and air-source heat recovery systems and other heating applications where a non-toxic classification is preferred. High efficiency and more cost effective than MPG and bio-based coolants.

  • 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 FPG and FXC2.

  • Corrosion Control - Rating: ALong-Life formulation with synergistic corrosion inhibitors to exceed BS6580 and 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:1.04 - 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.

B BCBAA

Non-toxic geothermal heat transfer fluid with antifreeze function, for use in geothermal, GSHP & air source heat recovery systems. Based on propylene glycol and ASTM D1384 proven corrosion, scale and biological inhibitors.

Show more...

  • Summary - Rating: BSuitable for geothermal, GSHP and air-source systems where low toxicity is preferred. Average efficiency but higher cost compared with ECO based fluids.

  • Efficiency - Rating: CAverage thermal conductivity and higher viscosity at sub-zero temperatures, results in reduced heat transfer efficiency and increased energy demands, compared with 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 DTX and ITF.

  • Corrosion Control - Rating: ALong-Life formulation with synergistic corrosion inhibitors to exceed BS6580 and 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.
