Dohone intelligent nitrogen gas cabinet is a kind of drying cabinet developed by DoHOone in order to avoid the phenomenon of micro cracks and steam burst air welding after excessive high temperature caused by moisture in the manufacturing of IC semiconductor, PCB and SMT. Compared with the traditional nitrogen tank, DoHone intelligent nitrogen tank adopts the fully automatic mode and uses the humidity setting environment of 1%~, which can accurately detect the humidity change in the nitrogen tank and automatically control the nitrogen filling, thus effectively saving energy and achieving a good oxidation prevention effect, saving 27% nitrogen consumption. When products are stored, we have a safety alert function to better protect the items. Combined with users' application requirements for remote control of intelligent Internet of Things, we developed mobile APP and PC web intelligent Internet of Things platform, which can feed back the status in real time through the cloud control APP and save manpower. Also equipped with high load adjustable laminate, can be more flexible choice of storage object size. In order to meet the special needs of some manufacturers, DoHone intelligent nitrogen tank also supports datuk customization and flexible upgrading.
