Компактный солнечный подогреватель воды под давлением

integrative pressurized solar water heater Highly efficient vacuum tube absorbs heat from sunlight and heat pipe transfers heat to the condenser end of itself.Condensor indirectly contacts with water through a copper cap and it boils water by releasing heat gained from vacuum tube. Characteristic 1. This type of solar water heater works with high pressure, so do the water it produces It uses the heat pipe to delivery the heat energy, it can works rapidly. 2. Because of no water in the vacuum tub, so there will no tube breakage in the winter. 3. Each vacuum tube can work alone, so it can still operate in the event of occasional tube breakage. 4. Works well in the cold place even -35 5. Working Pressure:6bar,testing pressure:12bar Specification 1. Inner tank:SUS304 2B food grade stainless steel,1.2mm thickness 2. Outer tank: Color steel or Stainless steel ,0.4mm thickness 3. Heat preservation: Polyurethane 50-60mm 4. Capacity:100L,150L,200L,250L 5. Optional accessory: Electric Heater,Controller
