SRE provides solar thermal system solutions, especially for industries. Our evacuated tube based technology is based on non-pressurized Solar Systems, where water is directly flowing in the vacuum tubes. This increases the efficiency and the high water content ensures stable operation conditions. Combined with the forced circulation controlled solar pumps, works efficiently under all conditions.
Shifting energy perspective for a clean heating solution.
The solutions not only provide a significant reduction in energy costs but are also sustainable and environmentally friendly. Solar heating systems harness renewable energy to deliver consistent and efficient thermal solutions. These systems are ideal for applications such as water heating, space heating, and industrial processes, ensuring long-term energy savings.
Solar Water heating systems
Components of the Solar water heating systems
Evacuated Tubes
This type uses the all-glass evacuated tube solar collectors as the heat-absorbing element. The high vacuum degree of the clearance between the outer and inner tube reduces the heat emission, which is caused by convection and conduction. The layer films (coating) of the all-glass evacuated tubes transfer the sun energy into heat energy. The high absorption and low emittance rate of Sunray’s layer films is unique.
Manifold
The manifold is made of stainless steel. The header is a pair of contoured copper pipes with dry connect sockets that the evacuated tubes plug into. The manifold casing is made of a strong but lightweight stainless steel that is folded to form a strong protective enclose. In addition the glass wool insulation is literally baked like a cake to form a complete structural shell around the header pipe.
Mounting Frame
The mounting is easy to install with various options and settings according to different mounting methods.
Working Principle
Step 1
The absorber coating on the inner glass tube (Evacuated Tube) Absorbs sunlight and converts it into heat.
Step 2
The Inner tube transfers heat to the water in the tube which transfers heat up to the manifold.
Step 3
A pump circulates water are heat transfer fluid through the header pipe.
Step 4
The energy from the solar water heating system is recovered and store in the storage tank.
Step 5
The Storage tank can be boosted by a gas-oil boiler for increasing the reliability of the system.
