400L water tank with double coil stainless steel solar water tank with high quality and best price

Specifications

1,Germany improted blue titanium absorbers
2, Laser welding for copper and absorber
3, 25 years lifetimes,SRCC Solar Keymark

 

 

The following is our solar collectors’ advantages:

 

1)S-type tube flat plate solar collector,have gotten the line patent in China.no any welding on

  the tube,no any leakage.

 

2) Laser welding between whole absorber panel and copper tube, high strength thicken heavy

 

duty aluminium frame.

 

3) The instant heat efficiency of the collector can up to 81.1%,much higher than the 72%

  standard,very rare in China.

 

4)Germany imported high efficient selective blue titanium coating.use best copper tubes in

  domestic.

 

5)Special low-iron tempered glass with transmittance more than 92%.

 

6) Mechanical load, freeze resistance, rain penetration, exposure, hail impact, external and

internal shock tested etc.

 

7) Long lifetime, large absorber area,good warm keeping , European,North America special

designed.

The following is details of solar water heater system with double coil tank working principle :

 

1)  When the temperature difference between solar collector and tank reaches the set value, 

the controller will start the circulation pump automatically,contrarily, In case the when the 

temperature difference between solar collectorand tank do reaches the set value, the 

circulation pump will be shut automatically.

 

2) The circulation pump makes heat-conducting liquid circulate automatically .

 

3) The heat-conducting liquid transfers heat to water by heat exchanger in the water tank

 

4) our water tank has electrical auxiliary heating system, when the temperature of the water

 tank does not reach Tmax, electrical heating system will start to work .

 

 

Our split solar water heater system is 150L ,200L,250L,300L,400L,500L ,which are pressurized

system with enamel inner water tank or stainless steel inner water tank ,Besides , we can also

provide compact pressurized solar water heater system - 150L,200L,300L, the more solar water

heater system specifications please email with your requirement !!

         

 

 

   

 

                           

 

 

 

 

1) Laser welding strengh tensile test

 

 

2) Resistance to high temperature aging tes

 

    Quality requirements:

 

a, after test, appearance  have no    

    deformation, discoloration, stratification of volatile fade, crack and breakage.

 

b, after test, under the performance of the prescribed temperature, 

    all the performance parameters of carbide change should comply with the 

    relevant standards 

 

3) Impact resistance test

 

   Quality standard requirements:

   The test result judgment criteria: 1.0 m, no broken, no crack of qualified

 

4) Rainfull test

 

 

 

5) Visible light through/ reflectivity test

 

    Quality standard:

 

   a,no dark marks in the test products smooth surface which should be clean, no

   variegation, bubble, crack,qualitative, defects such as gas line.

   b,Light transmittance >= 91% or higher 

 

6) Hardness test

 

   Quality standard requirements:

 

  a,the material is black, the hardness is  type A 70 degree  +/- 3

 

  b,material surface is smooth and soft elastic.
