Sunda - Model SEIDO1 Series -Heat Pipe Vacuum Tube Solar Collector
Sunda collector modules consist of an array of SEIDO evacuated tubes, insulated manifold header, support frame and standard frame package for single roof installation. Manifold headers have capacities of 8, 16 tubes. The collector manifold casing and end cap are made of powder-coated aluminium profile. The copper inlet and outlet pipe nipples come standard in Ø22 mm, making plumbing connections quick and easy using readily available metric compression fittings. The connection between the heat pipe and manifold is critically important to ensure optimal heat transfer.
The manifold header pipe is mounted within the manifold casing and is made of Ø28 mm, 1 mm thick copper pipe rated for a maximum pressure of 10 kg/cm² - standard use is 6 kg/cm². The heat pipe vacuum tube collects heat from sun working with high efficiency and absorbing more than 92% of the incoming irradiation. Thereafter, the condenser of the heat pipe will transfer the heat to the manifold where the water is heated. The heated water will circulate in the system until the required temperature is attained. The heat transfer liquid of the heat circuit does not flow through the collector itself. This allows a very simple installation and guarantees an exceptionally trouble-free operation. The operation of the system will not be interrupted even if one of the collector tubes should get damaged. The manifold is mounted in a FCKW-free insulated box that largely protects the collector against heat loss. With its two vertical supports and the bottom support the insulated box provides a stable frame for the collector module.
