Flat plate solar thermal collector is suitable for residentialor commercial solar water heating projects. The titanium coated aluminium absorber sheet absorbs up to 95%of available sunlight converting into usable heat for hot waterproduction. High efficient of 80.5% for 2 sqm of flat plate collector with titanium absorber. For water and space heating, can be used for hot water application below 65 degree C. Scope of delivery - Fully pre-assembled collector unit Installation types - Pitched roof, flat roof Advantages and benefits - Easy and low cost installation due to fully pre-assembled simple collectorstructure. - Long operating life and stable performance. Performance characteristics - Large aperture area and high collecting efficiency. - Full closed system adopts ion-free cycling medium to prevent scaling in thecollector. Glass Toughenedglass (glazing) protects the absorber from the outside environment whileallowing through >90% of sunlight. Absorber Athin sheet of Aluminium is coated with a highly selective material that isextremely efficient at absorbing sunlight and converting it into usableheat. The aluminium sheet is ultrasonically welded to the copper riserpipes. Insulation Theinsulation helps reduce heat loss from the sides and back of the collector.Made from ultra-light weight polyster foam, this material is chosen to greatlyreduce the weight of the collector. BackSheet Agalvanized sheet seals the back of the panel and adds to the rigidity of thecollector. Riser& Header Pipe Theheader and riser pipes are brazed together to form a harp shaped heat exchangerthat the solar system heat transfer fluid circulates through. Theabsorber sheet is ultrasonically welded to the riser pipes, thus transfers heatto the heat transfer fluid.
