high quality,fast delivery and best service

Solar split pressurized system;Split pressure solar water heater system


working principle of Ontek split pressurized solar system:


the solar collectors gather energy and heat the medium material in the copper pipe,the medium transfers the heat to the water


in pipeline in solar collector.when there is temperature difference(settled by customers) between the two sensrs in the


collector and tank respectively,intellegence controller activates the circulation pump automatically,and forces the flow of heat


medium in the pipeline and do heat exchange with the water inside the tank via copper coil in the storage tank.in case the


temperature of the water tank does not reach T-max,then start the auxiliary heating device.


Characteristics of Ontek solar split pressurized system:


1.the split pressurized system is composed by heat collector,storage tank,solar controller,working station ad installation parts


2.solar collector is separated from storage tank,so the tank can be put in any place of house,and the collector can be put on the inclined or flat roof


3.module design,arbitrary combination,harmony with the building perfectly


4.intelligent control and automatic operation


5.anti-freeze:no water in the tubes when it works,also the system controller has the anti-freezing function which the temperature circulation will operate while it reached the fixed temperature


6.multifunction:bathing,washing,demestic heating etc.


7.the system can work at anytime and use enjoyably
