home solar system Item No.:MSSA58-15 Specification:separated pressurized solar water heater Material: Inner tank:stainless steel SUS304/2B. 1-2mm Outer tank:galvanized steel:0.5mm Bracket:aluminum alloy:1.6mm Insulation:polyurethane frothing:50mm Vacuum tube:tri-elements coating.copper heater pipe inside:58 X 1800mm Copper coil inside of tank:one or two coils Accessories:working station.electrical heater. intelligent controller. Capacity:150L 200L 250L 300L 500L The separated pressurized solar water heater compose of solar collector / storage tank / controller / working station and installation parts Working principle: 1).when the discrepant temperature of the solar collector and water tank reaches.the set valve.the controller shall start the circulation pump 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).In case the temperature of the water tank does not reach Tmax.then start the auxiliary heating device. 5).if discrepant temperature of the collector and the water tank does not reach the set valve.the circulation pump shall be shut aoutomatically. Feature: 1).Collector separates with the storage tank.the tank can be put anywhere of the house 2).And the collector can be put on both tilted roof and flat roof. 3).Module design.arbitrary combination,harmony with the buliding prefectly. 4).intelligent control and aoutmatic operation 5).Anti-freeze:no water inside the tubes when it works 6).the system controller has the anti-freezing function is that the temperature circulation with operate while it reaches the fixed temperature 7).Multufunction:Bathing.Washing.domestic heating. 8).workable at anytime and enjoyable
