SFA is the compact non-pressurized solar water heater for family use that relies on the principle of thermosiphon to actively carry out natural circulation.
1. Product Description
The solar vacuum tube absorbs light energy through the AL/N/AL/SS/CU coating and converts the light energy into heat energy stored in the insulated water tank. It relies on the thermosiphon principle heat the water tank by natural circulation. Tank is the open loop type, bearing no pressure, known as low-pressure (non-pressure) solar water heaters.
2. Feactures and Specification
Actively carry out natural circulation by principle of thermosyphon, 100% solar energy, and no running cost.
Hot water drains out from tank by gravity. Water pressure is determined by the difference between the installed height of the solar tank and the height of the hot water outlet at user side.
The inner tank is made of food grade stainless steel SUSU304. It is fully automatic argon arc welding and double-sided argon gas protection to effectively prevent the surface from being oxidized. Strict welding process control is better to protect the crystal structure of SUS304 from damage. The inner tank can be used for more than 15 years.
The insulation layer of solar tank is polyurethane having independent bubbles and foaming density 36KG/m³, which resuts in a hot water temperature drop less than 2 °C in 12 hours. Under the ambient temperature of 25 ° C, water temperature can maintain at a stable level for 24 hours, and it will not deform for a long time.
Double-layer vacuum tube, AL/N/AL/SS/CU coating, absorption rate >92%, reflectivity<8%, 15 years service life.
Automatically add water in the tank.
Anode protection, protect the inner tank from corrosion.
Auxiliary heating equipment.
Intelligent control of Integrated non-pressure solar water heater.
Increase the water pressure of the outlet water, and the hot water is more comfortable to use.
