Ninjo is an effective flusher disinfector that offers a wide range of design possibilities.

Choose from colorful polymeric or stainless steel finish, and either free standing, wall-mounted or under-counter models, to suit your sluice room needs and preferences.

Ninjo features a control panel with digital display which clearly indicates the disinfection level as well as remaining time to complete the cycle, allowing you to keep track of the cycle progress and plan your workflow.
Ninjo cleans receptacles with a series of high pressure water cycles delivered through strategically located fixed and rotating nozzles, followed by a thermal steam disinfection phase.

Digital A₀ value and remaining time display
Digital display clearly indicates A₀ disinfection level as well as time remaining until end of cycle.

Cooling fan
Built-in cooling fan dries containers quickly and cools them with HEPA-filtered (H13) air.

Reduce risk of cross-contamination
Door remains locked to ensure no spillage throughout cleaning and disinfection cycle. Ninjo uses thermal steam to disinfect receptacles, after which the Pipe System Disinfection (PSD) disinfects its internal pipe and nozzle system.

Two programs available: economy and normal, with an additional three available upon request.

Flexible design options
Available as a free-standing, wall-mounted or under-counter unit. Choose from stainless steel or colorful polymeric finish.

Compatible with wide range of accessories, Arjo Liquids Flusher Rinse, and Arjo Liquids Flusher Detergent.
