1.All Glass Vacuated Tube All glass evacuated tubes are the key component of solar collectors. 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. The outer side of the inner tube is coated with a sputtered solar selective surface. This coated inner tube is closed at one end and sealed at the other end to the outer tube. The annular space between the outer tube and inner tube is evacuated to virtually eliminate heat loss by conduction and convection. We use the tubes which use the successfully developed innovative Advanced Solar Selective Coatings in commercial scale, which achieve the highest thermal efficiency and good thermal stability. Solar selective coatings absorb most solar radiation while simultaneously suppressing the thermal emittance loss from coating surfaces. They vary mainly in their optical property and thermal stability. Excellent results have been obtained by using DC magnetron sputtering technology. A solar absorbance of 0.94 - 0.96 with an emittance of 0.04 - 0.06 at 100 centigrade has been achieved.

The evacuated tube is a product with improved geometry and performance and consists of two concentric glass tubes which are sealed in a semi-circular shape on one side and are joined to one another on the other side. The space between the tube is evacuated and then hermetically sealed (evacuated insulation). To use solar energy, the internal glass coated with an environmentally friendly, highly selective la er on the outside, thus turning it into an absorber. The coating is protected in the evacuated space. The aluminum nitride sputter coating used is characterized by an ex u extremely low emission and a high absorption rate
solar tube light for outdoor lightings Solar street light for road lighting 7-8meter pole
Our solar vacuum tubes has prosperity of high absorption and low emission. The vacuum tube consists of outer tube, inner tube, (al-n-ss-cu) coating and holder.Al-nn-ss-cu is coating for three target tube. Three target assimilate the advanced 12 layers of spattering deposition of trivalent element technology, high borosilicate glass, and gradual change of al-n-ss-cu selective complex absorptive coating. These make three target vacuum tube have high performance of absorption and low reflection ratio. Because of the coating, three target vacuum tube’s absorption rate increase 30%-50% than normal tube.

Heat pipe vacuum tube Products detail: Perfect combination of the vacuum tube and the heat pipe. 1.High heat efficiency: advanced heat transferring style of the heat pipe, excellent sclective absorptive coating and perfect combination with high vacuum heat preservation. 2.Wide applicable ranger: as the heat pipe has less heat capacity, it can be started quickly even under cloudy day and collect heat effectively.It can work normally even -30?, as no water in the vacum tube, it can effectivelyprevent lowing of heat efficiencydue to frost cracking. 3.Each individual tube can work independently, and the whole machine can still work if andy single tube was broken.And the service life of the heat pipe can be over 15 year. 4.The unique connection between the heat pipe and the vacuum tube canensure both sealing and glassvacuum tube avoid damage.
Difference between three high efficiency solar vacuum tube (effective tubes, high cold tube, high temperature special efficiency tube)and ordinary tube: Absorption of heat membrane layer is difference between these two kind of tubes. (Absorption of heat membrane layer is the key part of vacuum tubes.) Absorption of heat membrane layer of three high efficiency solar vacuum tube is interference membrane, common tube is gradient membrane. The difference is mainly for interference membrane and the gradient membrane distinction. 1. Fundamental distinction: membrane layer structure is different, the principle of the absorption of sun's rays result in differently. gradient membrane, for multilayer, its absorbing layer is generally 9 layers. It to the sun's rays are layered absorption, and its absorb the light performance gradually become tall. Because the gradient structure, launch with increasing temperature rise than work, that temperature in 300 to 500 C than when launch greatly increased. The aluminum ions and absorbing layer in high temperature condition, lively nature greatly enhance the, and develop a drift. This happened in the internal structure of membrane layer caused confusion, coating began to aging. In the long run, the high temperature condition, membrane layer can fall off, thereby affecting the vacuum tube heat efficiency and life integrating. Interference membrane, its absorbing layer altogether 2 layer, among two layer membranes, because the metal content between the different and interfere ratio effect, make absorption ratio increase, launch ratio decrease. Plus effect of reduce emission from minus reverse layer, thus achieve more higher absorptance and reducing the role of launch ,greatly improved collection thermal efficiency. 2.Features: Absorptance of three high efficiency solar vacuum tube increased by 12%, and launch reduced by 30 to 40 percent, the super absorbing, heat loss less, warming faster. Efficient tube, the super absorbing, thermal efficiency is high, warming faster, in the same light conditions, can create more and higher temperature water than common tubes ; high cold tube, copper ions for the launch of aluminum ion mantua, so low 0.2 thermal loss rarely, in high cold environment can still work normally. hot water turn out as usual under- 30 C. high temperature special efficiency tube, because the membrane layer stainless steel ion high temperature resistant, fight air drying. Membrane layer under the condition of the 400 C, not attenuation, not aging, discoloration. In the same light conditions, ordinary tube heat absorption is lower than three high efficiency solar vacuum tube, can't even meet requirements that wash bath; In lower temperature, heat loss is bigger, collection hot effect is reduced, affect the normal use; Especially in the empty sun over 270 C, membrane layer began to aging, fall off, absorption rate drastically reduce, life shortens greatly. 3.Technology: high temperature special effects tube, high cold tube, efficient tube used respectively to three target, double target, single target magnetron sputtering craft; Ordinary tube typically use the single target magnetron sputtering technology. 4, appearance: A, Mouth of tube, here membrane layer above 800 C high temperature condition sealing off part is inevitable. As high temperature special effects tube has high temperature resistant, only 1 cm long without membrane layer in mouth of tube, while others without membrane layer for without high temperature resistant, tube membrane layer falls off the length is about 2.5 cm B, Inner tube color: with macroscopic observation, high-temperature tubes and high cold tube for internal color is kermesinus (for membrane layers bottom is copper); the bottom And efficient tube and ordinary tube are white (for membrane layer bottom is aluminum). Anyhow, interference membrane is the new breakthrough basis of gradient on membrane technology ,it is the great innovation in coating technology progress and become current global, interference coating of the most advanced coating technology. But also to the vacuum coating technology bring epoch-making change. Especially with the high temperature effects made interference membrane, can also be used for cooling tube, dry, seawater desalination, opened up the update for vacuum tubes wider application fields.

SUN PIPE SUN TUNNEL -SOLAR LIGHT TUBE - Capture, Transmission and diffusion of natural lighting. Chatron's SUN PIPE SUN TUNNEL -SOLAR LIGHT TUBE are systems for capturing and transmitting natural Daylight to the interior of the buildings where they end with the solar diffusers. The dome is placed on the outside and maximizes the capture of natural light that will enter the SUN PIPE SUN TUNNEL -SOLAR LIGHT TUBE and route it to the solar diffuser placed inside the installation. In the background it is as a Light Tunnel. The great advantage is that it can bring natural light to spaces that were otherwise was practically impossible to illuminate: lighting for indoor bathrooms, corridors, cellars etc. The domes, SUN PIPE SUN TUNNEL -SOLAR LIGHT TUBE and solar diffusers have unique and selective features, so they transmit the good light and eliminate harmful light (UV, and part of the Infrared) so that the heat or cold transmission to the interior is residual.
