pressurized solar collector

1.come out with pressurized hot water 2.still work with several tubes broken .

Features of this pressurized solar collector :

Evacuated tubes convert solar energy into thermal energy that is transferred to stainless steel tubes by an aluminum fin with high solar energy absorption and low radiance loss .Solar collector can still work even with several tubes broken !

 

The detail of material

outer tank:Al-Zn coated steel sheet/color steel

Inner tank:SUS 304-2B stainless steel sheet

Insulation: polyurathane foam

Vacuum tube:borosilicate glass 3.3

Inner pipeline:stainless steel tube with aluminum fin

Absorption coating :AL/Copper/stainless

Stand:aluminum alloy/galvanized sheet

Work pressure:0.3MPa

  

The cost is higher than non pressure solar collector, because it has the stainless steel pipes inside vacuum tubes, most suppliers use copper inside, but we compare cost and efficiency, we find stainless steel is cheaper than copper, but efficiency is similar!

it is not heat pipe or U-pipe, it is direct flow system, just add a stainless steel pipe, water heated by tubes, goes up directly into manifold, no anti-freeze liquid or others, just water.

U can connect this type to your electrical boiler or gas heater or other pressure heater directly. It also can be used as a part of split system .
