Non Pressure Bearing Type System
Advantages
- Can be operated automatically if connected with intelligent controller.
- Simple structure, easy plug-in installation, can be installed both on flat and inclined roof, and can be used with an auxiliary electric booster as to provide hot water without sunshine.
- Superior heat preservation ensured by one-off molding polyurethane foam with thickness 55mm.
- Suitable for camping area, holiday residences.
- Stable and reliable performance, well wind resistance.
- Meet the mankind healthy bath standard: The material of inner tank is SUS304-2B stainless steel plate; the silica gel ring sealing has a long life against the erosion and it not harmful to health.

Testing the leakage by auto leakage testing machine |
|
In terms of the tank which is the most important core of a solar water heater. We are testing every tank before they leave the factory, and most importantly, we are testing the leakage by auto leakage testing machine, which will have a much higher testing pressure and longer testing time.

The Principle of thermosyphon
Because of the larger proportion of hot water than cold water, cold water flows downward and hot water goes upward. The water will be heated continuously between water tank and vacuum tube. In other words, hot water always floats on cold water.
The hot water flows to the water tank from the vacuum tubes. Because of the proportion, cold water flows to vacuum tubes from the water tank.
The cold water is heated in vacuum tubes. After it becomes hot water, it flows to water tank again. The water circulates constantly between water tank and vacuum tubes; the cold water in water tank will be hotter and hotter.
Finally, all cold water will be heated to be hot water. This is the heating course of cold water.
Specifications of the material
- Inner tank: stainless steel 304-2B, (food-graded), Thickness: 0.40mm
- Outer tank: stainless steel 304-BA, Thickness: 0.40mm.
- Insulating layer: 55mm high-density polyurethane foamed.
- Glass tube: three target vacuum tubes 58*1800mm, High borosilicate glass 3.3, with thickness of no less than 1.6mm. The hail resistance will reach a diameter of 30mm.
- Bracket: Aluminum(1.5mm)
Vacuum Tube
- Vacuum tube: 3.3high borosilicate glass
- The vacuum tube of our solar water heater has the high absorption rate and low emission rate,
- The absorption rate is 0.93-0.96(AM1.5)
- The emission rate is 0.04-0.06 (80C±5C)
- Vacuum tightness is P≤5.0*0.0001Pa
- Idle sunning property parameters is Y=260-300㎡.c/KW
- The average heat loss coefficient is Ult=0.4-0.6W (㎡.c)
Electric Heater |
|
In terms of the electric element, we are adopting the best Electric heater, with in glass structure. (Fig. 1) You can find that the electric heater was not immerged inside the water directly; they are protected by the glass cover made of quartz. And this structure will strengthen the life span of our electric heaters and also can offer a best clean hot water comforts. |

Magnesium Stick
We provide Magnesium stick (to protect inner tank form corrosion).
Features:
- Made of magnesium
- Anode Protection
- To set magnesium ion free in the tank
- To prevent perceptible substance to cling interior of the tank
- To keep the water clean

Intelligent Controller
This controller (TK-7Y) can control the electric heating either automatically or manually.
It can show the temperature of the water & it is easily adjusted according to your desire.
- Temperature Indicator: The actual display water tank temperature
- Temperature Pre-set: 30-80° Celsius
- Time Heating Auxiliary heating temperature control three time periods
- Manual heating according to Manual button to start the electric heating to a pre-set temperature of cessation of heating

Assitant Tank
The small tank of stainless steel guarantees that the tank is always full of water all the time
Products Features:
- Supplying water automatically and stop working when the big tank is full, it can serve 24hours in a day.
- Its operation basics on the gravity and float ball, environment friendly and power saving.
- The temperature of big tank will fall down evenly; the users never suffer the hot-cold water suddenly.
- The big tank is always full, so the big tank can resist higher strong wind power
