High Efficiency Non Toxic Heat Transfer Fluid with Antifreeze. Based on Ethylene Glycol blended with patented DeTox™ additive and ASTM D1384 High Temperature Rated Inhibitors for use in Biomass Heating Systems.

BioTherm DTX has been especially formulated for the Biomass sector to exploit the advantages Ethylene Glycol has over Propylene Glycol, whilst delivering a non toxic solution. Specifically;


Antifreeze AntiFreeze

BioTherm DTX is miscible with water in all proportions and can protect Biomass Heating Systems down to -50°C depending on concentration.

non toxic Non Toxic

Although based on Ethylene Glycol, BioTherm DTX has been tested and classified as Non Toxic by an EPA certified laboratory. Previously Propylene Glycol was the only non toxic glycol available, that is no longer the case. Hydratech in alliance with Evans Cooling Systems, Inc. have developed and patented the DeTox® additive. DeTox® prevents Ethylene Glycol from being metabolised (during digestion) into toxic by-products, which cause kidney failure, blindness and death. Tests carried out on BioTherm DTX confirmed the toxicity was "so low that it was impossible to determine an LD50 value".

The DeTox® additive has very little effect on heat transfer or antifreeze performance. In fact similar volumes of BioTherm DTX or Ethylene Glycol are required to achieve a specific freeze protection.

Optimum Flow Optimum Flow

BioTherm DTX has improved heat transfer characteristics. Including lower Dynamic Viscosity and higher Thermal Conductivity. For detailed comparison please refer to the Fluid Performance Chart - available upon request.

Corrosion control Corrosion Control

BioTherm DTX contains synergistic corrosion inhibitors to protect metals commonly found in such systems. It has been independently tested and found to meet BS6580 and ASTM D1384 corrosion standards. BioTherm DTX also contains scale and biological inhibitors to help prevent fouling – thus promoting long operational life and high thermal efficiency.

Biodegradable Biodegradable

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

Qulaity 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 and debris prior to commissioning.

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

Determine the total system volume and add BioTherm DTX to the system according to the minimum operating temperature required (see table). The minimum dose of BioTherm DTX should not be less than 22% 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 bulk tankers.

BioTherm DTX can be supplied as a Ready-To-Use solution.
