a Elements of heat collection: Adapt fully high effective vacuum pipe of Suunny super conduct technology. Inner bag of water tank: Adapt imported qualified PP (Polypropylene) material Case of water tank: Choose imported SUS304 staninless steel or color coated steel or Zinc galvanized steel plate from Japan; Heat preservation material: Adapt polyurethane imported from Japan through high pressure high density integrated machinery foaming, constant tem perature+aging treatment. Its light hole is fine and uniform. Its density is reasonable and its rate of pore closed is high. Its effect of heat preservation is best. Being adapted macromolecular Si rubber material that is popular in the world, therefore its life is over twice than that of common silicon rubber. End cover of water tank: mould one time, wale and prevent from bogus, inner lock, made from aluminum alloy material (Compared with common thin aluminum alloy material, its strength will increase twice), compared with plastic end cover its life is longer. Design of bracket: Choose thickened zinc galvanized steel plate through press molding. Adapt corrosion resistant treatment and anti-UV radiation plastic sprazying; Run automatically: It can be equipped with microcomputer full automatic control meter to display water temperautre and level. Feed and stop water auto matically, heat automatically, creepage protection, control automatically.
