1)Inner water tank shell all are made of SUS3042B food grade stainless steel plates, welded by argon arc. Outer tank and frames are made of color steel or zinc-coated material. Water is pure and drinkable. Inner tank thickness is 0.4mm, the highest thickness for SP-R direct insert lower pressure can be 0.8mm.2) Heat insulation of water tanks adopts polyurethane foam and the thickness is 55mm3) Silicon rings to connect and seal them4) The tubes and supports are adjustable. The power bearing is average and can assure the vacuum tubes to use for a long time5) Whole glass vacuum tubes adopt super hard borax and silica glass6) Absorption rate: ≥93%, thermal radiation rate: ≤6%7) It resists 25mm hail and the using life can last 15 years8) Temperature when exposed to sun without water: 250,2.5 hours to boiling point if using single tube9) If you use electrical appliances to aid heating and to switch off the power supple before bathing10) Please test the water temperature before using, in order to avoid scalding.
