Capacity: >200L Working Pressure 6 Bar: Maximum Pressure 9 Bar 85% Absorption Efficient: 3/4 Inch Connection Garantee 5 Years: Life 15 Years Anti-Freeze -40c: Closed Loop Trademark: Forte/OEM Transport Package: Export Specification: EN12975 Origin: China HS Code: 84191910 Product Description Heatpipe high pressure solar collectorMain FeacturesWorking pressure 6 bar, maximum pressure 9 barSplit system : Collector on the roof, tank in the house, use a circulation pump to help with the circulationCLosed loop : no water flow through tubes , even one tube broken, the system can still workRoof intergratedHigh efficient : vacuum tubes use 3 target high efficient tubes, with AL-CU-SS coatingAnti-freeze -40C , this system can be used in extreme cold area , like RussiaHow does the heat pipe collector work?Sunlight is captured by the coated vacuum tubes which absorb the radiation as heat and conduct it through aluminum fins to the heat pipes. The liquid inside the heat pipes vaporizes as it is heated and the vapor rapidly rises to the condenser (top), releasing the latent heat, and condenses to form a liquid and returns to the pipe bottom where it evaporates once more and repeats the cycle. A manifold on the top of the solar collector allows a working fluid (typically anti-freeze) to absorb the heat from the top of each heat pipe. The working fluid is pumped through the manifold and then through an external heat exchanger which transfers the heat to water in a pressurized storage tank.FeaturesHigh purity (99.97%) copper heat pipe features excellent corrosion resistance and can stand high temperature up to 250C. The degradation of heat transfer property is less than 5% within 5000 hours.Unique cold welding technology seals in the special working fluid inside of the heat pipe, ensuring that air will not enter.The first fully automatic copper pipe cleaning line in the industry ensures higher performance and longer service life of the pipes.Hot-DIP galvanized steel frames and aluminum alloy frames with adjustable angles are available.A complete testing system developed by Forte Solar ensures that all the heat pipes delivered by us have undergone stringent tests.MODELTank capacity(L)Tube quantityAbsorber area (m2)Loading quantity20GP/40HQ(set)FT-L-HP-58/1800-12100151.22123/286FT-L-HP-58/1800-15125151.22120/230FT-L-HP--58/1800-18150181.4682/191FT-L-HP-58/1800-20167201.6273/170FT--L-HP-58/1800-22185221.7967/150FT-L-HP-58/1800-24-C200241.9656/130FT-L-HP-58/1800-25-C210252.0552/120FT-L-HP-58/1800-28-C235282.3048/105FT-L-HP-58/1800-30-C235282.3045/104
