2. Features and specifications
The natural circulation is actively carried out by the principle of thermosyphon, and the pressure of the hot water is large and equal to the running water pressure.
The water tank is a pressure-bearing structure, with a test pressure of 0.9Mpa and a working pressure of 0.6Mpa.The inner tank material is food grade stainless steel SUS304 by fully automatic argon arc welding and double-sided argon gas protection. Inner tank can be used for more than 15 years.

The solar water tank is insulated with polyurethane having independent bubbles and foaming density 36KG/m3, which results in less than 2 °C temperature drop of hot water within 12 hours. The temperature can maintain at 25 ° C for 24 hours, and be not deformed for a long time.
The solar heat pipe is a phase change heat transfer design with fast heat energy start-up speed. When heat pipe is under sunshine, its temperature can reach 222 ° C soon, conbributing to making high temperature hot water. The system uses double-layer solar vacuum collector tube with AL/N/AL/SS/CU coating, absorption rate >92%, reflectivity<8%. and service life 15 years.
1. SR609C controller: display water temperature, fully automatic control.
2. Electric heating: auxiliary heating equipment.
3. Magnesium rod: anode protection, protect the inner tank from corrosion.
4. Thermostatic valve: automatically control the outlet temperature according to the setting.
5.Water Pressure Rregulator valve: SFO-PR15 Water Pressure
Rregulator valve acts to keep the system pressure stable and
depressurized, which can avoid the influence of unstable
water supply pressure on the solar hot water system.
3. Product installation and case
Installation and use steps: select the installation location, assemble frames, place water tank on the tank holder, install solar heat pipes, connect hot and cold water pipes, add water into tank to check there is leakage or not, fix the system, use in normal, make regular inspection and maintenance.

4. Warranty and certificate
Solar vacuum tube and bracket: 5 years.
Water tank: 3 years.
5. Packaging and transportation
The solar vacuum tube with heat pipe is packed in carton, and the carton is equipped with anti-pressure foam. We will add plywood cases extraly for package of goods under LCL shipment.
