Solaris DTX has been especially formulated for use in Solar Thermal Heating Systems to exploit the advantages Ethylene Glycol has over Propylene Glycol - whilst delivering a non-toxic solution. Specifically;
- More efficient heat transfer.
- Easier to pump, especially at low temperatures.
- Less volume for the same freeze protection.
- Cheaper per litre.
Solaris DTX is miscible with water in all proportions and can protect Solar Thermal Heating systems down to -55°C depending on concentration.
Although based on Ethylene Glycol, Solaris 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 Solaris 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 Solaris DTX or Ethylene Glycol are required to achieve a specific freeze protection.
Solaris 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.
Solaris DTX has been tested in accordance with BS5117 procedures and found to meet BS6580 and ASTM D1384 corrosion standards. Solaris DTX also contains scale and biological inhibitors to help prevent fouling – thus promoting long operational life and high thermal efficiency.
Solaris DTX also contains a high temperature rated polyacrylate, formulated to prevent sludge precipitation and scale formation. Thus promoting long operational life and high thermal efficiency.
Solaris DTX mixtures are readily biodegradable (90% over ten days) and will not remain in the environment or bio-accumulate.
All Hydratech products are manufactured in accordance with certified ISO9001-2008 procedures
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 Solaris DTX to the system according to the minimum operating temperature required (see table). The minimum dose of Solaris DTX should not be less than 35% of the system volume and the maximum does not normally exceed 45%. 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.
Shelf Life: >3 years when stored in sealed containers out of direct sunlight.
