Metal Glass Vacuum Tube Solar Collector
Fast start-up; Low heat loss; High vacuum with long-term stability; High pressure resistance. Minimum maintenance requirement

  Feature:1.?Using high efficient metal glass vacuum tubes consist of a single glass tube. Due to the curved aluminium plate coated with Al-N-O selective coating inside the tube and the copper heat pipe be attached, metal glass vacuum tube own a high efficient absorption, perfect heat conduction and low heat capacity;2.?Suitable for regions where water quality is unfavorable . The system has been designed to ensure that the condenser or 'heat exchanger' at the top of each solar tube never comes into direct contact with the water circulating in the system, while assuring a highly efficient heat transfer process.3.?The high quality insulation in the manifold ensures minimal heat loss.? 4.?High durability and reliability, due to the high quality of the materials used in the manufacturing process.5.?High performance, even in adverse weather conditions due to vacuum insulation;6.?Ease of installation - each tube can be installed individually;7.?Minimum maintenance requirement - a single tube can be replaced at a time.8.?Each system is secured to the roof by means of stainless steel fixing brackets. In the case of a flat roof, a stainless steel frame is available to set the collector to an optimum angle.9.?Applications range from simple domestic hot water supply to commercial and industrial heating and coolingSpecification:1.?Manifold casing: aluminium-alloy / aluminium /stainless steel;2.?Frame material?: stainless steel/ aluminium-alloy/galvanized steel;3.?Header pipe: red copper; 4.?Insulation: rock wool;5.?Glass tube: 70mm*1700mm metal glass vacuum tube;6.?Rubber seals and rings: silicone rubber;7.?Maximum operating pressure:?8bar - 116psi8.?Stagnation temperature: 190 Celsius degree;9.?Conversion factor: ho = 0.717;? Loss coefficients: a1 = 1.52, a2 = 0.0085
