Our systems are used in the vacuum tube 24s - 30s -36s pieces 1800mm length glass tubes length. storage capacity of 190t 240t 300t are are divided into three. In these systems 30 lt extension tank used. in ex- tension tank used chrome-nickel stainless steel float ball. Internal storage plate 304 the outer covering 430 quality stainless steel plate. Also inside serpantine 304 quality stainless steel chrome. Serpantine working pressure is 6 bar but we test 12 bar. Repositories to provide insulation between the inner tank and outer stealth was placed 5 cm polyurethane insulation. Vacuum tubes used our system nested been obtained by combining two of the tube. selective in the interior of the tube surface. Combination air vacuum between the two tubes. this, heat loss may occur when tubes are minimized. vacuum tubes solar water heater can be used in even the severe winter conditions. store in glass tubes used in polyurethane insulation and vacuum air warmed up in the system is designed to maintain the temperature of the water for a long time. vacuum tubes used in the system in provided
