This application system called Solar BK has the outstanding advantages of being safe in the process of using, saving electric energy and harmless to the environment.

Solar BK equipment is composed of a solar radiation absorption unit and a 2-layer insulated hot water tank. Cold water is supplied to the system from a cold tank set higher than a hot tub. Thanks to the pressure difference, the principle of the bottle is interconnected, the cold water will automatically flow into the hot tub without using the pump. The heating time for the hot water tank from the solar radiation plate averages about 4 hours to get the necessary amount of hot water for the whole day.

Saigon Hotel in District 1, Ho Chi Minh City is one of the first places to install 30 Solar BK systems to provide hot water for 106 rooms since 2005, saving more than 60% of the electricity used by the entire customer. hotel compared to before.
