- Company Name : Worldsunny Solar Energy Co.Ltd
- About Us : Worldsunny Solar Energy Co.Ltd Worldsunny Solar Energy Co.Ltd based in jiangyin , China. We are member of Tradekey.com since June, 2008. Our business is related to Energy Products industry and we specifically deal in solar water heater. Please find our product details below: Heat pipe solar collector Manifold Powder coated zinc galvanised steel with 50mm Rockwool insulation compressed at 70Kg/Cubic M. Many manufacturers use polyurethane insulation which is not environmentally friendly, unlike Rockwool. Heat Pipe 0.6mm Oxygen free copper, diameter 8mm with 1mm aluminium fin. Tested to 250C. Oxygen free copper must be used, as otherwise leaching may result which can lead to a point of weakness. Copper Header 99.93% copper, rated and tested to withstand 1.2Mpa. Brazed with Silver/Copper/Zinc. Evacuated Tube - 1.6mm thick borosilicate glass, double skin vacuum with glass-glass seal. Selective absorber coating of Copper/Aluminium/Titanium. Max absorptance >93% and able to withstand temperatures of up to 400C giving greater tube life expectancy. In addition our tubes are 58mm x 1800mm which gives 30% more efficiency than many suppliers standard of 47mm x 1500mm. Frame 2.0mm thick Aluminum Alloy with all bolts, fixings and straps of the same. Rubber components are vulcanised (UV treated) to give a maximum working temperature of 300C. Separated pressure system flexible assembly, combined with building in perfect.solar collector composed of vacuum tubes, which is good in pressure bearing, high efficiency and sanitation. Tank can bear 2Mpa pressure.All the system with close circulation desgin. And with electric back up inside for no enough sun ***** if in cloudy or raining day, you can enjoy hot water. Separate pressurized solar water heater takes advantage of high absorptance and low emittance of vacuum tubes and converts absorbed radiation into heat energy and sends it rapidly to collector by heat pipe ***** can work efficiently in four seasons. Thermosiphon system The thermosiphon system is Worldsunny most straightforward, cost and energy efficient solar system and requires low maintenance. Its high efficiency provides hot water after only a few hours of sunlight. This is the eco -friendly answer to a family’s hot water needs. Based on natural water circulation and requiring no pump or control unit. Worldsunny thermosiphon systems are available for Warm Climates - Open-loop system This simple and economic system is suitable for climates where there is no freezing risk. Mains Water flows into to the tank and then to the lower part of the collector where it is heated. The water ascends in the collector as it is heated and flows on to the tank, and from there on to the user. An electric backup system provides energy during periods of cloudy weather. Cooler Climates - Closed-loop system A close-loop system uses a wide-surface heat exchanger and allow adding of anti-freeze liquid. This system helps to avoid the buildup of scale in the collector. Heated water from the collector flows into the heat-exchanger, and then returns to the collector. The electric backup system provides energy during periods of cloudy weather. Compact pressure system 1.2mm thick armor plate with 5 mm thick especial anti-corrosion coated(food grade) inner tank outer tank : stainless steel 304 it uses the heat pipe to delivery the heat energy , it can works rapidly. because of no water into the vacuum tube, so it has some advantage , no filthy, no tube broken, anti-freeze, unlimited time of the inputting water and pressure operation Frame: stainless steel 1.2mm which is strong and against corrosion Reflector: bright light aluminum Thank you for taking the time to go through our business profile.
