Separated in manifold + frame, and vacuum tube cartons.
Electric booster,temperature controler value,P/T valve,anode,one-way,a TCO cap, temperature sensor. Overheat protection,it includes protection of solar collector and electric booster. Pressure limitation,it functions by automatically sensing the pressure and temperature of the parts,so as to ensure the normal operation of the system. Anti-freezing,it is realized through the circulation of working fluid to make sure
the safety of the operation at the limited temperature.
U Pipe Solar Collector
In each vacuum tube there is a U pipe with direct flow-through that is connected to the header pipe inside manifold. This U pipe is seamed in an aluminum heat transfer fin in the interior of vacuum tube that transmits the heat from the interior tube to the U pipe. Solar radiation permeates the outer glass tube and is captured on the outside of inner glass tube by highly selective sputter layer. The captured solar radiation is transmitted to flush-contact aluminum shield and then copper pipe filled with heat transfer fluid. The 360°aluminum heat transfer fin assures the fastest energy transfer.
