12tubes U pipe vacuum tube solar collector

How does U pipe vacuum tube solar collector work?

U pipe solar collector is a kind of pressurized and efficient solar water heating device, heating flowing water or liquid in closed flow passage and U pipes with glass tubes, since the copper flow passage is welded with U pipe, water or liquid will never flow into glass tubes. U pipe collector is composed of three-target tubes, U pipe manifold and supporting bracket, and it is commonly used in active solar water heating system.

Detail specification of U pipe vacuum tube solar collector :

1.    solar collector box: inner box flow pipeline with red copper diameter 38mm; out box: aluminum alloy case 2mm. 

2.    Heat preservation: Rock Wool foaming

3.    Frame: aluminum alloy steels,strong structure,light weight.

4．U pipe: copper material, with glycol as heat conduct medium for anti-freezen.

5．Angle for working:15-60 degree

6.Tube size and no.: 58*1800mm ;12tubes

7.Hail resistance:25mm

8.Coating of vacuum tube:ALN/AIN-SS/CU

U pipe vacuum tube solar collector features:

1. It is one of the most efficient solar collector which is widely used in active hot water heating system, supplying hot water for domestic applications, dormitories, hotels, restaurants, schools, hospitals, factories, swimming pools, etc. 

2. The flow passage and U pipes is closed and pressurized, water or liquid will not flows into glass vacuum tubes, no freeze expansion or inner thermal shock to break vacuum tubes.

3. U pipe tip is welded together with copper flow passage, withdrawal or breaking one or several glass tubes will not drain the collector loop.

4. Aluminum alloy as manifold shell and bracket makes the collector superior in chemical resistance, universal bracket suitable for slope and flat roof installation.

5. Modularized collector, arbitrary combination with any architectural structure, adaptable to slope roof or flat ground or upright walls, maintenance free collector

6. The collector can be used in -40degree  weather with anti-freezing liquid for heat conduction.

7. System efficiency: >55% in summer and >42% in winter

There are other range of U pipe vacuum tube solar collector for different installation request.

15tubes,20tubes,24tubes,30tubes

They are designed for solar modules connecting use. U pipe vacuum tube solar collectors can be installed in series for large hot water project such as hosiptal ,hotel,school,SPA,airport and other commercial area.
