The 200-liter integrated non-pressure-bearing solar water heater is JDSOLAR's leading product, which is mainly used by household users in Africa, the Middle East, India and Southeast Asian countries, and has a price advantage.
Non-pressure-bearing is the difference between the use of water and the principle of water flow to the lower part, that is, the higher the position you put, the better the water flow.
The non-pressure water heater is called the in-line all-glass vacuum tube solar water heater. Because the vacuum collector tube and the water tank are sealed by the sealing rubber ring, they cannot withstand the pressure. The non-pressure water heater is used for falling water in a non-pressure state, that is, the water in the water tank is discharged by the drop. The main pipelines in the lower part of the water tank are the inlet/outlet pipe and the overflow pipe: after the water tank is full, the overflow pipe overflows the alarm and shuts off the water supply valve; when in use, the hot water flows out from the inlet/outlet pipe by gravity under the action of gravity At this time, the overflow pipe acts as a qi. Since there is water in the vacuum tube of the non-pressure water heater, if one tube is damaged, the water in the water tank will all flow out. However, the "JDSOLAR" brand all-glass vacuum heat collecting tube material is borosilicate glass, and the possibility of natural disaster damage is extremely small.
Water tank housing
Choose SUS304 all stainless steel or painted steel plate and galvanized sheet imported from Japan.
2B food grade stainless steel, high frequency welding, the weld is in the advanced of the water tank, and the weld seam will not leak for a long time due to the corrosion of acid water.
The use of today's international high-quality polymer high-quality Si rubber material, life expectancy is more than twice as long as ordinary silica gel.
Water tank end cap
One-shot molding, embossed anti-counterfeiting, internal locking, (twice the strength of ordinary thin alloys).
Heat collecting device
All three high-efficiency vacuum collector tubes are used.
It can be equipped with microcomputer automatic control instrument to display water temperature and water level, automatic water supply and water shutoff, automatic heating, leakage protection and automatic control.
High quality insulation
It adopts imported polyurethane high pressure, high density integral mechanical foaming, constant temperature + ripening treatment, fine and uniform cell, high density and high closed cell ratio, and excellent thermal insulation effect.
Efficient heat collection performance
JDSOLAR's new generation of solar vacuum collectors uses nano-molecular technology, which greatly enhances the absorption ratio, increases heat collection by 20%, higher water temperature, the same solar light, and different hot water efficiency.
Adopting international advanced coating technology, the photothermal conversion rate is extremely high, even if it is cloudy, it absorbs heat, and the heat collecting and discharging process greatly improves the effective heat collecting area under the same water capacity compared with other solar water heaters, without the need for reflectors. Can achieve the "good winter" standard.
The vacuum tube has the characteristics of small thermal expansion coefficient and high strength, and can resist the frontal impact of the hail below 25 mm.
Robust and reliable structure
The bracket is made of thick galvanized steel sheet for stamping, comprehensive anti-corrosion treatment, anti-UV spray, can be installed on a random slope, and strengthens the anti-cracking ability, which is twice as long as the ordinary cold-rolled sheet. Choose the best angle for winter lighting is 45o; Emgrand series use thick alloy profiles, through oxidation treatment, can be installed on a random slope, enhance wind resistance, long service life than ordinary square tube bracket, choose the best angle for lighting is 45o heat Strong, beautiful appearance.
