High Absorption U Pipe Solar Collector 25 Tubes With 25 Degree
Adjustable Aluminum Alloy Frame
Working Theory & Parts Description:
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.
Features of 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.
Application:
high pressure evacuated tube solar collector with U pipe is usually
used in active closed loop system with connection in series and
parallel for domestic and large-scale commercial solar water
heating applications, such as hot water for real estate, hotels,
factories, hospitals, schools, swimming pools, space or floor
heating, etc.
Warranty:
6 years international responsibility for U pipe solar collector and
15 years for vacuum tubes due to original quality problems.

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 PTU 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.
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 water & glycol mixture heat
carrier;
3. No system drainage even though one or several tubes are broken;
4. More convenient in system parts carrying and installation;
