Flat panel solar collector flat plate solar collec

Flat panel solar collector ,flate plate solar collector, solar water heater ,solar heater panelWorking principle: 1) When the discrepant temperature of the solar collector and water tank reaches the set value, thecontroller shall start the circulation pump automatically 2) The circulation pump makes heat-conducting liquid circulate automatically 3) The heat-conducting liquid transfers heat to water by heat exchanger in the water tank 4) In case the temperature of the water tank does not reach Tmax, then start the auxiliary heating device 5) If discrepant temperature of the collector and the water tank does not reach the setvalue, the circulation pump shall be shut automaticallyFeature: 1) Collector separates with the storage tank. The tank can be put anywhere of the house 2) And the collector can be put on both tilted roof and flat roof 3) Module design, arbitrary combination, harmony with the building perfectly 4) Intelligent control and automatic operation 5) Anti-freeze: no water inside the tubes when it works 6) The system controller has the anti-freezing function is that the temperature circulation will operate while it reaches the fixed temperature 7) Multifunction: Bathing, washing, domestic heating 8) Workable at anytime and enjoyableDetailed Product DescriptionNet Dimension (mm): 2000*1000*83 (also could produce according to your request).Collecting area: 2TPR Header Tubes: 25 *δ0.8 * 1060, 2pcs ,Copper(TP2)TPR Riser Tubes: 10 *δ0.5, 7pcs, Copper (TP2)TPR Riser Tubes Shape: Straight line typeAbsorber Fin: 140 mm, 7pcs, Copper (TP2)Welding method: Ultrasonic weldingSpectrum Absorber Coating: Blue CoatingAbsorptivity : a≈91%±2%Emissivity: 4%±2%Insulation Material: Rock wool covered with black glass fleeceFrame: Aluminum alloy frameGlass (Selectivity): 4mm, Ultrawhite tempered glassHeat Transfer Fluid: propylene glycolBacking Sheet: 0.4mm galvanized plate/AluminumNet Weight (kg): 40Package Dimension (mm): 2060*1060*140Qty for 40' GP Container: 277 PCS
