50 Tubes Stainless Steel Project Solution Vacuum Tube Thermal Solar
Collector with High Efficiency
Specifications
Solar collector project
certification: ISO9001,CCC,CE,Solar Keymark
solar water heater: evacuated tube
pressure type: non pressure
Working principle
1. thermosiphon solar collector works in this way:warm water rises
when the phenomenon known as natural convection happens and water
circulates between the collectors and tank.the tank must be
installed above the collector.
2. as water in the collector is heated,it becomes lighter and
naturally rises into the tank above.meanwhile,cooler water in the
tank flows downwards into the collector,thus causes circulation
throughout the system,these systems are reliable and relatively
inexpensive.
Material
1. volume of storage tank:500L,1000L,2000L,3000L,4000L,5000L
2. non-pressurized water tank:
insulating layer,polyurethane foaming ,thickness:55mm
outer shell of tank,stainless steel ,thickness:0.4mm
inner tank,stainless steel SUS304-2B,thickness:0.5mm,normal working
pressure:0.4bar,
3. dust ring gasket :ABS
4. evacuated tube:three-target tube,high boron and silicon,content
3.3,structure,gradual change SS-AL-Nx/Cu,selective absorption
coating
5. frame: aluminum alloy 2mm thickness
6. controller
Advantages
1. can be operated completely automatic if connect with intelligent
controller.
2. Simple structure,easy plug-in installation,can be installed both
in flat and inclined roof,and can be use with an auxiliary electric
booster as to provide hot water without sunshine.
3. Superior heat preservation ensured by one-off molding
polyurethane foam with thickness 50-55mm.
4. Suitable for camping area,holiday residences.
5. water introduced into vacuum tube
6. long service life,can be used as long as 15 years
