Test pressure9barOptimal installation angle30-70°vertical, O° horizontalWorking principle:1)When the discrepant of the solar collector and water tank reaches the set value, the controller shall start the circulation pump automatically.2)The circulation pump makes heat-conducing liquid circulate automatically.3)The heat-conducting liquid transfers heat to water by heat ehchanger in the water tank.4)In case the temperature of the water tank dose not reach T max, then start the auxiliary heating device5)If discrepant temperature of the collector and the water tank does not reach teh set value, the circulation pump shall be shut automatically. 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 building perfectly4)Intelligent control and automatic operation.5)Anti-freeze: No water inside the tubes when it works6)The system controller has the anti-freezing function is that the temperature circulation will operate while it reaches the fixed temperature.7)Multifunction: Bathing, washing, domestic heating8)Workable at anytime and enjoyable.Our advantages:Our products process:  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
