Our centralized water heating systems include solar collectors, buffer tanks, controller systems, electromagnetic valves, circulating pumps, appurtenances and so on. The principle is that the collectors make cold water warm and then circulate to the buffer tank by circulating pump.The heated water isthen transferred to individual heat exchangers in the in-house tanks on respective floors/levels, and circulated back to the roof on loss of the preset temperatures.
This system uses flat plate, U-pipe or heat pipe collectors, whichare filled with a non-toxic heating fluid, normally distilled water or a mixture of the water and propylene glycol, which lowers the boiling point. The fluid absorbs the heat energy through the collector from the sun and vaporizes to steam, flows through a copper pipe coil in the water tank that acts as a heat exchanger, thereby heating the water. It then condenses back to fluid, which is then pumped back to the collector. The process is repeated until all the water is heated. The system has an intelligent controller that controls the flow of the heating fluid by utilizing temperature sensors in the collector and the water tank
Solar thermal Controlle is an indispensable part of any solar water heater. It controls The water level and temperature of the panel. Our solar thermal controller has two models, tk-5 automatic controller is designed to meet the basic needs. and tk-7 intelligent controller offers all the vital functions for user's convenience
Simple production process and lower production cost. The inner tank is easy to make, only needs one step blow moulding and doesn't need a lot of labour and equipment investment and thus it will help customers save more production cost.
