TECHNICAL INFORMATION:
- The collector frame is made of corrosion resistant, special Aluminium Extrusions and the bottom of the collector is covered using Aluminum sheet.
- The bottom and the sides of the collector are insulated with high temperature resistant Rock Wool slabs to prevent radiation of heat to the surroundings.
- Collectors are Single glazed with Toughened / Tempered glass. The glass is fitted with Rubber Beading around its edges to ensure that the collector is air tight and there is no heat loss from the collector.
- The parts of the collector are assembled such that they can be easily dismantled during service and reassembled.
- The absorber surface used in the collector is SOLCHROME Selectively Coated Fin-N-Tube. The Fin is selectively coated with Nickel and Black Chrome. The SOLCHROME selective coating is more efficient that any other coating. This efficiency is achieved by the unique properties of the coating, which is applied in a thickness that matches the wavelength of the incoming Solar radiation. Once the solar energy is absorbed by the Solchrome solar selectively coating, the wavelength changes before it is re-radiated, very little of the heat energy is emitted. 96% of the Solar Energy falling on SOLCHROME is absorbed while only 12% of the energy absorbed is emitted. On days of low sunshine or low ambient temperature, solar collector using SOLCHROME can outperform any other surface coating by delivering tow or three times more energy.
- Solchrome solar selectively coated fin & tube.
Bonding
SOLCHROME selectively coated FIN & TUBE are TIG welded in a continuous process. There is no use of Solder or adhesives as in mechanical joints. The Metallurgical bonding achieved ensures a very high degree of thermal efficiency. It also ensures that the bonding can stand up to high degrees of stagnation temperature (300° C).
Conductivity
Normal Bonds like solder, adhesive or mechanical require a very much wider joint in order for the fin to transfer the heat without additional resistance. On the other hand metallurgical bonding achieves unrestricted transfer of heat from the Fin to the Tube.
Durability
As the bond between the FIN & Tube is metallurgical and also as there is no third metal like solder used to join the FIN & TUBE, the durability of the joint is very high.
- None of the inputs in the collector contains any corrosive parts. The minimum life of the absorber material is 20 years.
-
The Solar tank is fabricated using Stainless steel (304) which ensures hygiene and long life. It is insulated with high temperature resistant Rock Wool. The insulated tank can retain the hot water at the same temperature for about 48 hours.
