Hygienio B1.N1 is the simplified model in the use and management of functions. Since the electronic control unit is not provided, the phases of verification of the system status, of the correct mode of delivery (with disinfectant or steam only) and their selection are direct and manual. The control of the level of liquids in the tanks is visual, with also the purpose to avoid possible damage to the internal components.

Due to its own features and dimensions the model B1.N1 is recommended for out-patients departments, medical practices, dentistry and environments of smaller size than those in which the C4.PO and D1.HIDC models are used.
