Beijing Sunda Solar Energy Technology Co., Ltd. products

SEIDO1 is a heat pipe vacuum tube with a flat absorber profile. SEIDO1 tubes have large dimensions with an outer diameter of 100 mm and a length of 2000 mm. The heat transfer from the absorber to the heat circulation is performed by the heat pipe which is mounted in the absorber. This heat pipe had originally been developed for the thermal control in satellites. Inside the pipe, the heat is conducted with high efficiency to its upper end. From there it is released to the heat circulation. Although the heat transport medium of the heat pipe is water the heat pipe is a closed system. The pipe is charged with a small amount of water and carefully evacuated before sealing. Since the heat transfer liquid of the heat circuit does not flow through the collector itself, installation is very simple and an exceptionally trouble-free operation is guaranteed. The operation of the system will not be interrupted even if one of the collector tubes should get damaged.

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.

Dimensions(mm): 1640×992×35. Weight(kg): 18.5kg. Solar cells: monocrystalline (156.75x156.75mm 6×10). Construction: Front: 3.2mm high transmittance reinforced glass; Back: Anti-aging film; Frame material: Anodizing aluminium alloy.

Compressor, evaporator, condenser, fan and water tank are all integrated in a single system, the overall design, elegant appearance. The installation subject to site constraints, simple and convenient, without connecting pipe plug can be used. Intelligent control, automatically adjust the load sensing temperature changes, improve system protection. Optimized structure design, high efficiency heat exchanger, compact, strong corrosion, safe and reliable. Pressure tank, water temperature stability, good insulation properties, safe and clean water; direct water according to water pressure, water is big, strong water, bathing comfort.
