Solar Vacuum Tube

Let's say the Purple Golden Glass Vacuum Tube tube is in purple golden color which will make it more beautiful and special.This product adopts magnetron sputtering technology (SSALNx/Cu) ,which are able to ensure very high absorptivity and very low emissivity .

The above solar heat pipe is hollow with the space inside evacuated, much the same as the solar tube.Based on this principle of water boiling at a lower temperature with decreased air pressure, by evacuating the heat pipe, we can achieve the same result.

Have you ever see any vacuum tube with purple gold color ? they are so psecial and powerful. The efficiency of a evacuated water heater is dependent upon a number of factors, one important one being the level of evacuated radiation (insolation) in your region.

The absorption layer of the heat pipe solar vacuum tube, stainless steel instead of aluminum ion, and more heat. Interference film in the temperature rises, the emission ratio changed little.and the speed of the heating transfered is absolutely good. This tube adopts to the pressurized solar hot water heater.

Three Target Solar Vacuum Tube is the core component of the solar water heater. Its performance lies on the actual film coating technology.And this three target solar vacuum tube have three level coating(CU-SS-ALN).The absorption rate of the three target solar vacuum tube is 93%~96%. And according to the vacuum level,it has little heatloss.

Solar Evacuated Tube :Improved molecule structure of plated selective coating, attributed to DC magnetron sputtering technology, makes the highest of vacuum tube working temperature as high as 300℃, effectively preventing the coating from bursting, aging, discoloring, function attenuating because of long time burn under the sun, prolonging its lif

Evacuated tubes have already been used for years in Germany, Australia, France, Japan Canada, China and the UK.The kind of vacuum tube assimilate the advanced 12 layers of spattering deposition of trivalent element technology, high quality borosilicate glass 3.3, gradual change of CU-SS-ALN/ALN selective absorption coating .

As you see the purple Solar Tube For Solar Hot Water will become nice and differet once they are be installed with special purple solar tube .The evacuated tube is similar to a conventional Dewar flask and consists of two borosilicate glass tubes, a glass with high chemical and thermal shock resistance.

Purple Solar Glass Tubes assimilate the advanced 12 layers of spattering deposition of trivalent technology,high borosilicate glass,gradual change of ALN/AIN-SS/CU selective complex absorptive coating.Ang these make vacuum tubes have high performance of absorptance and low reflection ratio.

Solar water heater vacuum tubes are the absorber of the solar water heater. They absorb solar energy converting it into heat for use in water heating. Each evacuated tube consists of two glass tubes made from extremely strong borosilicate glass. The outer tube is transparent allowing light rays to pass through with minimal reflection.

Both side open tube is the vacuum tube that you never seen before ,we have the invention right in China .this special spiral tube is widely used for water heating ,air heating .because of its new design and structure , it will beat more smiliar prodcut and win the market .

We have invention right on the spiral tube .it is widely used in air heating ,hot water heating ,food industrial ,vegetable planting ,floor heating and so on .
We have exported this both open solar tube to Danmark for big project . this system is still very hot in market .

Jordan is one of our biggest market for solar vacuum tube and hot water system .
With the help of DC magnetron sputtering technology, the absorptance of 0.88 - 0.92 and emittance of 0.04 - 0.08 has been achieved. The main absorbing wavelength ranges from 0.35μm to 3.0μm

The Solar Tube Copper Heat Pipe absorb solar onto the glass surface ,then transfer the heat to the copper pipe , the copper pipe transfer the heat to the condensider which is collected with the manifold .Heat pipe vacuum tube has advanced heat transferring,when the excellent vacuum tube combination with copper heat pipe.

The solar collector is made by solar copper heat pipe and manifold . the solar heat pipe is the engine of the whole system for hot water heating .8. To avoid the common water heater vacuum tube attenuation of long-term performance of air drying and other issues, longer life.

As a very important role in pressurized solar water heater ,the solar collector copper heat pipe heated by the energy, the medium in the heat-pipe is working and transferring the heat energy to the condenser zone. When water or other medium in the water pipe flows across the copper sleeves, they would bring the energy and be heated.

Excellent results of this solar collector pipe have been obtained by using DC magnetron sputtering technology. A solar absorptance of 0.94 - 0.96 with an emittance of 0.04 - 0.06 at 100℃ has been achieved.And longer life of this solar collector pipe also is an advantage.It can works even in very cold climates.

Under the evacuated tube circumstance , the air pressure inside heat-pipe is very low, thus the medium can be evaporated easily when absorbing certain energy.
This vapor rapidly rises to the condenser zone and transfers heat, then becomes the liquid and returns to the bottom of the heat pipe since the heat is lost .

Heat Pipe Solar Heater is the key part for solar hot water heating system .7. Super Anti-cold: advanced vacuum process, 450 ℃ high temperature for up to 60 minutes of strict exhaust, vacuum up to 5 * 10 (-4) Pa, cut off radiation convection heat, better resistance to cold, below zero 40 ℃ still work.

We offer a wide range of Solar Hot Water Vacuum Tube saving electricity and giving uninterrupted hot water supply. These are manufactured with the basic principle of black body absorption, where in heat gets absorbed by black body through a transparent borosilicate special tube.
