Warranty:

5 years international responsibility for U pipe solar collector and 15 years for vacuum tubes due to original quality problems.

 

Working Theory & Parts Description:

VISION VUC series high pressure U pipe solar collector is one of the most popular solar collector with pretty high efficiency. 

The selective three-target coating of vacuum tubes converts solar irradiation into heat energy and transfers to copper U pipes by aluminum wrapping, the water or heat transfer liquid pass through U pipes absorbs heat all the way, taking away the heat to store in tank water.

 

 

 

VISION U pipe solar collector is comprised of four main parts:

 

Vacuum Tube: Absorbs solar energy and converts it to usable heat. Vacuum between the two glass layers insulates against heat loss.

 

U Pipe: The VISION U pipe is a U-shape copper pipe with two sides welded into two seperate copper header pipes, the U pipes are wrapped with aluminum fin that absorbs the heat from within the vacuum tube.

 

Manifold: Insulated box containing the copper header pipe. The header is two seperate copper pipes welded with U pipes. The U pipe manifold bears high pressure and usually work in closed loop solar system for indirect solar water heating.

 

Mounting Frame: Strong and easy to install with various options to match different mounting methods.

 

 Features of VISION U Pipe Solar Collector:

1. One of the most popular and practical collector in solar water heating system;

2. Wide applications for water heating, pool heating, space heating;

3. Large heating capacity up to 100,000 Liter hot water;

4. Much safe and stable performance with high pressure;

5. Super anti-freezing performance to work in (-) 40°C;

6. Very efficient direct or indirect solar water heating;

7. Applicable to active closed loop or open loop system.

8. Strong adaptability to flat or slope roof installation;

9. Easy installation and connection with simple structure;

10. With no limitation in collector angle for installation;

11. More than 10 years experience from VISION company for consultation.

 

Advantages of VISION Heat Pipe Solar Collector:

 

Comparing with heat pipe solar collector:

1. Higher efficiency solar water heating;

2. No collector angle limitation in installation;

3. Bigger flow rate with more efficient heat exchange;

4. More adaptable to different building structure installation.

 

Comparing with vacuum tube solar collector:

1. High efficient heat pipe tubes;

2. High pressure and anti-freezing collector;

3. Less heat loss for closed loop circulation;

4. No risk of tube breaking from thermal shock;

5. No risky of tube breaking from water freezing.

6. No system drainage even though one or several tubes are broken;

 

Comparing with flat plate solar collector:

1. Higher efficiency collector, much lower heat loss with vacuum insulation;

2. Super anti-freezing performance with waer & glycol mixture heat carrier;

3. No system drainage even though one or several tubes are broken;

4. More convenient in system parts carring and installation;
