The warm water in the school hot water tank is not boiled, but cooled into warm water by physical cooling;

The heating mode of heat exchange is adopted in the machine, that is, the hot and cold pipes are nested with each other.

After boiling, the water passes through the pipeline outside the supercooled water pipe, which can physically cool down to about 50 degrees, and then comes out as warm water.

The cold water coming in from the water inlet passes through the pipeline inside the hot water pipeline and is heated before reaching the heating water tank.

Compared with the traditional water dispenser, the energy-saving efficiency can reach more than 80% by heating with normal temperature water;

Campus drinking fountains emphasize water quality safety, and usually can use built-in filtration system.

In areas with poor water quality, RO reverse osmosis filtration can be selected, and the filtered water can meet the standard of drinking cold water directly.

The upgraded direct drinking machine can be equipped with more functions, such as TDS water quality detection+filter element replacement reminder+time switch.

Under the condition of ensuring water quality safety, it can be used more conveniently.
