Split solar water heater manufactuer with flat plate soalr collector

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.                          Manufacturing technique difference                                  The following is details of solar water heater system 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       Quality requirements: 1, the strength tensile of welding >=10 Kgf.   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       Quality standard:      four hours in the rain,water into collector: <5 g/m2 or less.    Flat plate collector shall not be damaged and produce a large number of water vapor    and water droplets    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.   The more test items and each test process ,we will show you in our testing room when you come to visit our company.                                                                                                          The shipping date is estimated as the following :    European 25-35 days North America 12-35 days South America 30-50 daysAfrica   28- 60 days Oceania 16 to 25 days Southeast Asia 3 -10 days  Middle East   15 to 30 days   The specific shipping date should according to your actual delivery port.our FOB port is  Shanghai port ,delivery time is 10-30daysour solar system has two years warranty,we can quote you FOB Shanghai price , after you tell me your delivery port ,we will send you CIF or CRF price accordingly.        What are your main products?   Our company is factory in Suzhou Industrial Park, can provide you   Split pressurized solar water heater system (150L,200L,300L,400L,500L) Compact pressurized solar water heater system (150L,200L,300L) Solar water heater system for balcony (80L 100L 120L) Central solar water supplying project (1 ton ,8 ton, 20 ton ,30 ton ,50 ton ,) Solar building space heating /warming system Three kinds of solar water heater collectors( 2000x1000x80mm ,2015x1015x76mm,   2050x1050x95mm    Each products details ,please email me ,I can send your PDF file and video introduction    to introduce in details!   What is your MQO ,Payment , Production cycle ?   One set for solar system, two sets for solar collectors. two weeks production cycle.
