LSAD-58-1.8--HeatPipeVacuumTubeSolarCollector

Feature:<BR>1.&nbsp;Using a high efficiency heat pipe and heat transfer fin design to conduct the heat from within the all glass vacuum tube up to the header;<BR>2.&nbsp;Due to the vacuum between the two glass tubes, conductive and convective heat loss are eliminated;<BR>3.&nbsp;The tube is 100% glass, the problem with loss of vacuum due to a broken seal is greatly minimized, therefore, these tubes perform very well in overcast conditions as well as low temperatures;<BR>4.&nbsp;The evacuated heat pipes used in Lotusino solar collectors have a boiling point of only 30 Celsius degree (86 Fahrenheit degree) which leads to its rapid heat transfer and excellent low temperature performance;<BR>5.&nbsp;Due to the cylindrical absorber area, which passively tracks the sun throughout the day, Lotusino collector have a&nbsp; stable solar conversion all day;<BR>6.&nbsp;Suitable for mains pressure water (up to 8 bar/116psi);<BR>7.&nbsp;Easy plug-in installation;<BR>8.&nbsp;The perfect solar collector for domestic solar water heater systems, also ideal for commercial solar water heating applications.<BR>Specification:<BR>1.&nbsp;Manifold (interior): red copper;<BR>2.&nbsp;Manifold (exterior): aluminum alloy;<BR>3.&nbsp;Insulation: rock wool;<BR>4.&nbsp;Glass tube dimensions: 58mm * 1.8m;<BR>5.&nbsp;Coating of vacuum tube: ALN/AIN-SS/CU OR AL-N-AL;<BR>6.&nbsp;Heat preservation: 72 hrs;<BR>7.&nbsp;Hail resistance: 25mm;<BR>8.&nbsp;Heat pipe : anti-freezing &gt; -35 degree<BR>
