- Model NW50 - Sterilizer for Potentially Infectious Healthcare Waste



The Newster NW50 machine was designed for use in large hospitals and by waste disposers. The design allows the system to work for several shifts. Running the motor via the driver allows to leverage the power of the engine. The water recycling system guarantees maximum effectiveness, safety and work continuity besides a further reduction of running costs. A specially designed system for the discharge of the material allows the operator to manage the treated waste easily. The system can be equipped with an automatic loader.
