This device can be mounted on wall, and producing the distil water in lower cost, continuously, automatically and effectively.Operation: The tap water enters the bottom of the condense pipe and circle along with the pipe and enters the vaporize pan in the end, the height of the overflow be pre-set. The steam in the pipe go down and meat the water go up, thus to make the gas in it.The steam produced in vaporize pan reached the condense pipe through guide plate. The guide plate be installed as can change direction three times before the steam enters the condense pipe. This way can protection of bring tap water in the distil water, the tap water bring in the distil water is the main cause of chemical of distil water worse. If the working is normal, it can get the water of fyrogen-free. The vaporize, condense, overflow and guide plate inner are made in stainless steel. And the cover outside and the cover of guide plate are made in heat-resistant borosilicate glass, all the electric elements with safety cut off switch.
