Haining Chaoda Solar Collector Tubes Co., Ltd.
solar energy water heater collector product
Advantages:
1.Highly efficient absorber of high performance with daily average
efficiency over 50%;
2.Start up quickly, heat pipe transfer the heat energy into the storage
tank in one direction.
3.Withstand pressure of 6 Bar, can be connected directly with city
water.
4.No water inside the evacuated tubes; the solar water heater can still
in service even with several tubes breakage;
5.Highly efficient insulation with polyurethane foam;
6.Simple structure, easy to assembly and install, diffuse flat plate
reflector can be assembled easily with its module structure;
7.Can be used all year round in the cold climate;
8.Can be used together with Auxiliary electric boost;
9.Long service life, can be used as long as 15 years;
Solar vacuum tube is the most important segment,the following are the detail introducement.
1) Absorptivity:0.94-0.96
because of the copper insulation,the absorption of stainless steel and the decline heat of Aluminium layer.
2) Endure bad weather
Our evacuated tube can endure temperature to 250.C,even under -50.C since the vacuum rate can reach less than 5.0×10-3pa.
3) Structure stability
The tube prssure-endure ability can reach 1Mpa
4) Long life
Patented conducting substance is compatible with normal metal material that result in non-condensable gas and non-stop running within 15 years and long duration for the collector.
5) Advanced technology
Our company use 3 target magnetron sputtering plating technology,which introduce from Germany and also called interferometer coating technology.
