All-glass evacuated solar collector tube
----It adopts the special coating technique, which can absort ultraviolet ray, infrared ray, visible light and invisible light.
And the heat effect increases by 20% as a result of producing the maximum energy. The higher degree the vacuum tube has,the better effect the tube has on the heat preservation.You can make use of the products to get hot water in cold winter.
The characteristics of All-glass evacuated solar collector tube
●The material is double-deck boron silicon borosilicate glass 3.3
●It has the structure of double-deck and same axis.And the jacket becomes vacuum so that the tube can keep high degree of vacuum about 5*10-2 pa.
●CU/ST/AL和AL/N/AL selective absorption layer
●The efficiency of collecting heat is high. The selective absorption layer makes the thermal absorbilityα≥93％ and the thermal transmission rateε≤6％.
●It has a longer life.Generally it can be used for 15 years.And the heat is collected fast.Resist attenuation and water-dirty.The performance is stable.
●It has a good performance on enduring the climate.The heat efficiency is good all over the year.And it can withstand the shock of the hailstone which of the diameter is less than 25mm.
●12-layer coating technique is used.The absorption layer has the stainless aluminium nitrogen,which can endure the high temperature. Even if the glass melts,the coating will not drop.So that avoids the ageing and color changing which are produced as a result of long-term stagnation.
The heat preservation and the inner water tank:
The welding technique for inner water tank:
The best inner water tank is real the best.
The stainless inner water tank adopts automatic computer seamless welding techonology and is anticorrosive. The quality of the solar energy water heater depends on the quality of the inner water tank.But the inner water tank is packed in the insulation layer. So the consumers can't see it directly and always ignore it.The life span varies from 1 year to 30 years because of the different materials and the welding technique of the inner water tank.The inner water tank is one of the criterion for judging whether the products are branding.If it uses inferior stainless which is only 0.2-0.3mm, the life span is shorten and the structure is not stable.Manual welding and resistance welding can't gurantee the quality.The automatic computer cryogenic seamless argon-arc welding techonology is the most advanced at home. The welding seams in 2 sides is silver in color and smooth, homogeneous.The depth and the width of the melting are controlled strictly. The opening for welding is firm.Adopt automatic computer cryogenic welding techonology.The thickness of the oxidized layer is below 2u to protect the material. The oxidized layer of resistance welding is twice larger than that of automatic computer cryogenic welding.And the oxidized layer of manual welding is eight- ten
times as
large as that of automatic computer cryogenic welding.When the material is very thin,the manual welding will almost make the material broken.And it is easy to leak soon.
The welding between the inner water tank and connection is more important. Only can the advanced automatic welding equipment gurantee the quality. But it is common that the welding is made by manual,which of the price is 10 percentage of the automatic welding equipment. If you buy the manual welding product carelessly, it is unfavorable. The welding need excellent technique. The connection technology must be so accurate that it can be combined with the inner water tank well and the seam will be smooth and homogeneous. The thickness of the oxidized layer can be below 2u.J.Speedar's solar energy water heater connection has reached.The life span can be 15-20 years or even longer.
The lid of inner water tank is quite thick and radial.This is a bright point of J.Speedar solar energy water heater.Though it is invisible,it makes the pressurized effect better.If it is flat,it is easier to break the inner water tank when flooding water.Even the outer lid will be come out.
Support:
It is designed stably. And it is made of superior galvanized plate(part is made of Al.), utilize superior powders made by Akzo. Nobel and Tiger company, and six-layer treated.The support lustres and has good performance on anticorrosion.The life span can be 15 years.
Microcomputer controller
It adopts American Atmel chips and is stable,flexible.It has the best quality among that of domestic solar energy water heater.
Precise numerical control part for connection
The part for connection is precise numerial controlled.Its material is quite good and high-accurancy.The effect of welding is well and has good performance on anticorrosion.
Car paint，anticorrosion，good looking
The technique of face soft process is used, anticorrosion, good-looking and eye-protection.
Scientific assemble technique
It uses precise numerial control part for connection.Its material is quite good and high-accurancy.The effect of welding is well and has good performance on anticorrosion.
Patent technique:
The rubber foot cushion can protect the house surface.
It can protect the house surface effectively.The waterproof layer and the foot of the support will not be broken.
The cushion for protecting the tank can lengthen the use time of the water tank.
There is no cushion for protecting the tank in traditional design.So the water tank and support directly contact.When the water tank is full of the water,the surface of tank will have the mark due to the pressure.Also it will break the protection layer of tank.After a long time the tank will be corroded.But now the cushion for protecting the tank can solve this problem.
The surface has no irritation.
The technique of face soft process makes the product beautiful.So it won't hurt the eyes as a result of reflecting light.
The water in the water tank measures up to the hyqiene standards.
The processing meets hyqiene standards.The water in inner water tank and vacuum pipes meets the requirements of the drinking water.
There is large quantity in the water-outing opening.
The water-outing opening adopts the G3/4 connection, which is 80 percent larger than G3/4 connection.The water goes so fast that you can enjoy your bath better.Besides the water can be complemented in time.It is hard to form the water dirty to back up.
It is more reasonable to design the double-exhausting.
It is easy to have the water dirty in use because of the bad water quality somewhere.If the exhaustiong pipe is small, it is choked and can break the water tank.But using the G3/4 connection will not have this situation.At the same time, add the exhausting hole at the top to form the double-exhausting.It can eliminate the choking risks of having water dirty and freezing completely.
Four bright points:
Connection:
It is the G3/4 stainless304 seamless pipe. There is large quantity in the water-outing opening.Exhaust freely.It is hard to have water dirty.Bear the pressure and resit corrosion.If using other materials such as G1/2 connection,stainless 302,202,300,which of the nickel containing is only 1/4-1/6 of the stainless 304,it can't work so well.
The hole for adding foaming
The foaming is added through the hole.And the three-high foaming technique makes the foaming layer dense,no gap.So it has good effect on the temperature preservation.If it uses other foaming techniques,such as manual foaming and low-pressure foaming, the effect on the temperature preservation will be worse.
