vacuum tube Place of Origin: China Model Number: SS-HP Price Terms: FOB, CIF Brand Name: Sunstar / Blueclean Payment Terms: T/T, L/C Minimum Order: 10 sets Supply Ability: 10000pcs/day Delivery Time: 10 days Introduction: The new evacuated heat-pipe tube is a revolutionary breakthrough in the line of solar energy, as well as the symbol of a great leap in solar thermal utilization field. The tube has the following advantages: 1) It perfectly solves the problem of which can't run if one of the tubes is out of work 2) It prevents the tube from being easily broken caused by the volume expansion when the water in tube freezes in frigid season 3) There is no water in the tubes, so it is successfully prevented the defects of tubes' broken and lower power output caused by water fouling and deposits of mud and sand 4) Adopt high efficient selective absorptive coatings and low reflection ratio ensure the tube to get higher power output in cloudy weather and in moist area, especially in winter. Features: 1) Super conductive liquid in copper heated pipe 2) Without water in glass vacuum tube, product can be used in cold conditions -30ºC 3) Widely used in pressure solar water heaters and solar central water heater system projects 4) High-temperature-resisting, low-temperature-resisting, high heat absorption rate (obtaining a 12% available heat raise) 5) With hot water available even with poor sunshine
