Solar tank: Feature of Pressurized solar tank a),The solar tank is pressurized, working pressure is under 6bar b),Internal of solar tank, there have single or double copper coils as heat exchanger, one heat exchanger is connected with solar collector for transport heating energy to heating water, another heat exchanger for assistant heating by natural gas and others energy, also can connect with radiator for heating rooms. c),The solar tank is separated with solar collector, also it is pressurized solar tank, so the solar tank can install at washroom,kitchen,balcony or others convenience places . Material of pressurized solar tank a),Internal material: SUS304-2B , 1.0/1.5/2.0mm b),Insulation layer: Polyurethan foam, 42.5mm-50mm c),Outershell: color armor plate d),heat exchanger:copper pipe Accessories of pressurized solar tank: 1,Magnesium rod: Soften water, protection solar tank 2,Electric heater: assistant heating by electricity when the water could not satisfy your demand. 3,Check valve: prevent the water inside of tank back flow , generate negtive pressure will damage solar tank. 4,T/P valve: Safety valve, for release excessive pressure Supports:
