Solar vacuum tube, absorbs faster than normal tube. It's made by copper,stainless steel,aluminum. high efficiency&long life

All-glass three targets vacuum tubes, has excellent advantage of common glass vacuum tube and metal sealing-in vacuum tube. It gives full play to feature of "vacuum tube gathers a hot tube ".

Name: Three targets vacuum tubeModel: S58X1800mmFeatures: 1)fast start-up and response, it passes heat to water tank quickly. It can collect solar heat even in cloudy day. 2)It obtains high solar heat. 3)Hermetic seal in inner pipe. It can withstand high pressure. It can connect with system of tap water.  4)It stands against freeze weather. 5)it keeps warm for 24 hours.

6)Available size: 47mmX1500mm, 58mmX1800mm

7)Materials of tubes:copper,stainless steel,aluminum.

There are some advantages about the heat pipe type of vacuum tube sun water heater

1).it starts quickly, and the heat pipe heat capacity is small and responds quickly. The quantity of heat that collection heat pipe obtains may transmit the water tank rapidly. The clear low emissive weather also can have the effective collection heat in the cloudiness. But the quantity of heat obtained by in-line compact-like hot water collector is first used to heat up the water in the vacuum tube, and again it depends on the thermal siphon uses, to heat up the water in the storing hot water tank. Therefore the water heater starts slowly.

2).The quantity of heat of heat received is high:

    The quantity of heat obtaining from the heat pipe type entire glass vacuum tube is used to heat up the water in the tank of storing heat, so the heat received is high.

while the quantity of water heated by in-line compact-like water heater also includes the water volume unable to take out for use in the vacuum tube, so in them of the same body of accumulating the hot water tank, the quantity of heat is small relatively.  

3).The bearing pressure is high

The inner tube of heat pipe is sealed, and it may withstand the tremendous pressure, connected with aqueous system directly and originally, it can bear pressure use and be automatically used.

4). There is no water leaking in double vacuum collection heat pipe. Even some pipe break occasionally, the heater can still work.

5).Anti-frozen

There is no water in the vacuum tube, it won’t break even in the terrible cold weather.

6).the Heat pipe type vacuum tube has the function of hot diode quantity of heat unidirectional conduction, that is, when hot heat pipe doesn’t work, it can break from the tank.
