200L Compact Direct Thermosiphon Stainless Steel Non Pressurized Vacuum Tube Solar Water Boiler
Description:
It must be installed on the top, such as roof, to get enough hot water flow pressure by the gravity.
With the assistant tank or water tower, could be feed water automatic.
An simple controller can operate the electric or show temperature and water level inside the water tank.
Specification:
1. Inner tank: SUS304-2B food grade stainless steel,0.4mm
2. Outer tank: Color Steel with anti-corrosion layer.
3. Heat insulation layer: Imported PU(thickness: 55mm).
4. Vacuum tube:58mm*1800,Three target,1.6mm
5. Frame(Stand):Galvanized steel with Paint,1.5mm. 25 degree optional.
6. Working Temp.: minus 20 to 260 Celsius degrees
7. Working pressure: less than 0.5Mpa
Welded by argon arc
Pure and drinkable water
Heat insulation of water tanks adopts polyurethane foam and 55mm thickness
Silicone rings to connect and seal
Adjustable tubes and supports
Power bearing average
Can assure vacuum tubes to use for long time
Whole glass vacuum tubes adopts super hard borax and silica glass
Absorption rate: 93%
Thermal radiation rate: 6% (100°C)
Temperature when exposed to sun without water: 250°C, 2.5 hours to boil if uses single tube
Uses electrical appliances to aid heating to switch-off power supply before boiling
Test water temperature before using in order to avoid scalding
