Heat transfer fluid for solar heating systems

Anti-Freeze	Optimum Flow	Non Toxic	Biodegradeable	Corrosion Control	Quality Assured



SOLARIS DTX20 has been especially formulated to exploit the advantages Ethylene Glycol has over Propylene Glycol. Specifically;

• More efficient heat transfer.
• Easier to pump, especially at low temperatures.
• Less volume for the same freeze protection.
• Cheaper per litre.

Although based on Ethylene Glycol, SOLARIS DTX20 has been tested and classified as Non-Toxic1 by an EPA2 certified laboratory. Previously Propylene Glycol was the only non-toxic glycol available. That is no longer the case.3

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.4 Tests carried out on SOLARIS DTX20 confirmed the toxicity was “so low that it was impossible to determine an LD505 value”.

The DeTox™ additive has very little effect on heat transfer or antifreeze performance. In fact similar volumes of SOLARIS DTX20 or Ethylene Glycol are required to achieve a specific freeze protection.

SOLARIS DTX20 is able to operate efficiently at ≤170°C for prolonged periods and withstand temperatures of 200°C for short periods. It contains reversibly evaporisable inhibitors that are capable of withstanding stagnation temperatures of 300°C whilst protecting all metals used in Solar systems.

SOLARIS DTX20 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 DTX20 is readily biodegradable (90% over ten days) and will not remain in the environment or bio-accumulate.

SOLARIS DTX20 is a clear, slightly viscous liquid. It is mildly sweet to the taste and has a non-pungent but characteristic aroma.

As per BSRIA guide AG 1/2001.1 all pipe-work systems should be clean and free from biological contamination prior to commissioning.

To minimise corrosion air 6 ingress should be minimized. A pressurised system is best.

SOLARIS DTX20 is a Ready-To-Use Heat Transfer Fluid that will provide freeze protection down to -20°C. In order to maintain system integrity only top-up with SOLARIS DTX20.

1 According to the Hodge & Sterner Toxicity Scale, an LD50 rating between 500 – 5,000 mg/kg body-weight (bw) is classed as “Slightly Toxic” and anything above 15,000 mg/kg bw is classed as “Relatively Harmless” I.E. Non-Toxic.

2 EPA = United States Environmental Protection Agency.

3 SOLARIS DTX20 LD50 (Oral Rat) >21,000 mg/kg bw.
Propylene Glycol LD50 20,000 mg/kg bw.
Ethylene Glycol LD50 4,700 mg/kg bw.

4 According to the US Department of Health & Human Services as little as 150ml of Ethylene Glycol can lead to death and much smaller amounts can lead to renal failure in humans.

5 LD50 = Lethal Dose (oral) that causes the death of 50% of the lab rats.

6 Oxygen feeds the corrosion process and consumes inhibitors.
