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
