Dragonland Group Holdings Limited are based in Beijing China, PRC with branch offices in Hong Kong, United Kingdom and Africa.

Collectors and thermal storage tank separation, using flat-plate collector collector, water tank for the SUS304 stainless steel, solar collector loop fluid pressure medium to run.

Insulation is polyurethane foam insulation, water tanks built SUS304 coil heat exchanger, sunny days, solar radiation through the pump to force the energy cycle will gradually heat collector to collect water tank, the rainy days the water temperature is not enough, tank built by The electric heating system heated to the set temperature.

Tank with stainless steel coil heat exchanger, the water tank as a storage medium, through the sunlight, the heat stored in the tank, cold water through the stainless steel coil heat exchanger to absorb heat quickly heated, the water temperature near the temperature of the water tank (2 oC temperature), pressure from municipal pressure, dynamic pressure drop of about 5 meters.
