Heat Pipe Solar Collectors for Solar Water Heating System

Features description: The heat pipe solar collector consists of heat pipe vacuum tube, manifold, suppoting bracket and other accessories 1) Solar heat pipe and inner midium for thermal conduction, with a quick start and super daily efficiency about 55% in summer and 42% in winter. 2) No water to go through glass vacuum tubes, no freeze to break vacuum tubes, able to serve in extremely cold winter 3) Heat pipe tip is inserted into a closed cannula welded into the copper flow passage, system works well even with withdrawal of one or several heat pipe vacuum tubes 4) Aluminum alloy as bracket with super performance in every aspect, universal bracket suitable for slope and flat roof installation 5) Modularized collector, arbitrary combination with architectural structure, adaptable to either slope roof or flat ground or upright wall, Maintenance free collector Warranty: 3 years international responsibility for integrated system and 15 years for vacuum tubes due to original quality problems Certificate: CE, ISO9001: 2000, CCC       Heat   Pipe     Vacuum Tube  Spec.
