Higher Absorption, Almost Unbreakable

The tempered glass of the Dafa Solar Collectors is highly efficient and absorb 95% of the sunrays. Additionally, the glass has been designed to withstand shocks such as hailstorms or stray rocks flung on them during storms.

The Accessories:

The VHF-Antifreeze

VHF is an advanced mono polypropylene glycerol based, designed and formulated in order to ensure effective heat transfer properties at high or low temperatures on your solar thermal system while increasing its performance. 

Unlike most competitive products in the market, it is non-toxic and certified by InS with HT1 certificate, suitable for food contact; so, there is no health risk in case of contact with the water you use. Additionally, it protects your system against low temperatures during the wintertime and provides protection up to -32 ° C. Finally, is also specially designed to provide complete protection from corrosion caused by water and oxygen, providing a life span to your system.

The VXT-2 Expansion Vessel

The VTX-2 is a closed cylindrical expansion tank suitable for the closed circuit of the solar water heater. It is designed to protect both from the high pressure in the supply network and the pressure caused by the expansion of liquids in high temperatures. It also prevents the sudden pressure fluctuations that damage the system. Manufactured from stainless steel, it is suitable for drinking water. It contains no elastic or plastic parts and has no welds giving it an incredibly long lifetime.

 The Dafa Delta Frame

The advantage of the Dafa Delta Frame is the 45 degrees inclination angle giving a higher exposure to the sun in the winter months. It is manufactured taking into consideration resistance, stability and ergonomics. The Dafa Delta Frame is installed with screws and bolts without any weld. It is manufactured of galvanized hot rolled metal sheet of 2mm thickness in contemporary sheet metal manufacturing machinery that provide accuracy and flexibility to the final structure. The Dafa Delta Frame is designed to resist against time and under adverse weather conditions.

The Electrical Heating Element (Resistance)

All the Data Solar Water Heaters come equipped with a 2KW Heating Element (Resistance) coupled with a Thermostat. The resistance is made from 316 Grade Stainless Steel and is a screw-in type (of a 1.25 inches diameter) for the ease of replacement and maintenance. Additionally, the system is supplied by a Magnesium Anode for cathodic protection.
