Non-Toxic Heat Transfer Fluid with Antifreeze, for use in Geothermal & Air Source Heat Recovery Systems. Based on Propylene Glycol and BS6580 & ASTM D1384 proven Corrosion, Scale and Biological Inhibitors.

Thermox FPG has been especially formulated for use as a Non-Toxic heat transfer fluid for use in Geothermal and Air Source Heat Recovery Systems.


Antifreeze AntiFreeze

Thermox FPG is miscible with water in all proportions and can protect Geothermal and Air Source systems down to -50°C depending on concentration.

Thermox FPG exhibits super-cooling characteristics and mixtures containing in excess of 50% by volume do not freeze solid, alleviating any concern over possible expansion and burst damage.

non toxic Non-Toxic

Thermox FPG has an LD50 toxicity rating (Oral Rat) of ≥15,000 mg/kg of body weight (bw) = “Relatively Harmless”. As confirmed by the Hodge & Sterner Scale.

Corrosion control Corrosion Control

Thermox FPG contains synergistic corrosion inhibitors to protect metals commonly found in such systems. It has been tested in accordance with BS5117 and found to meet BS6580 and ASTM D1384 corrosion standards.

Biodegradable Biodegradable

Thermox FPG mixtures are readily biodegradable (90% over ten days) and will not remain in the environment or bio-accumulate.

Quality Assured Quality Assured

All Hydratech products are manufactured in accordance with certified ISO9001-2008 procedures

Application

As per BSRIA guide BG 29/2012 all pipe-work systems should be clean and free from biological contamination or debris prior to commissioning.

To minimise corrosion air ingress should be minimized. A pressurised system is best.

Determine the total system volume and add Thermox FPG to the system according to the minimum operating temperature required (see table). The minimum dose of Thermox FPG should not be less than 25% of the system volume and the maximum does not normally exceed 60%. We recommend the use of deionised, distilled or UltraPure™ water for this dilution. Avoid water containing high levels of calcium salts or Chlorides [Cl-].

Health & Safety: Please refer to the associated Safety Data Sheet. Available via Login or upon request.

Shelf Life: 3 years when stored in sealed containers out of direct sunlight.

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

Thermox FPG can also be supplied as a Ready-To-Use solution.
