MMDU-30

It’s a sterilizer that uses the dual effects of microwave and high-pressure steam to sterilize biohazardous Waste.
Treatment capacity appr. 2kg/hr. Perfectly suited for disposing of medical waste in medium or small sized hospitals, clinics or any health centre, Customs and Quarantine Departments, etc.

Specifications:

  • Treatment capacity: 17L/cycle, or appr. 2 kg/hr (±10%)
  • On-site medical waste disposal equipment for hospitals and clinics

    MOU series: MMDU-30

    Is a Microwave Medical Waste Disposal Unit that uses the dual effects of microwave and high pressure steam to sterilize Regulated Medical Waste (RMW), or medical waste with infection risk.

    Treatment capacity: appr. 2kg/hr (based on an average density of medical waste at 0.1kg/l ~0.15kg/l.)

    Sterilization bin volume: 30L

    Technical Principle

    The disposal unit first introduces high-pressure saturated steam into the high-pressure disinfection chamber of medical waste, while starting a microwave generator. It uses the thermal effect of microwave to heat the high-pressure disinfection chamber to maintain temperature and prevent steam condensation. It is sterilized by the sensitivity of bacteria to temperature. In addition, microwave has a non-thermal effect, Non thermal effect refers to other microbial killing effects besides thermal effect, which is a unique effect of microwave sterilization. The heating and warming process of the equipment is also a disinfection process. After the disinfection chamber reaches 135 ℃ or above, it is held for another 5 minutes to complete the disinfection.

    • High disinfection efficiency : 99.9999% sterilization in 5 minutes under the temperature and pressure conditions achieved.
    • Energy saving : Half the energy cost of autoclaves
    • Personnel-friendly & Eco: Below dioxin generation temperature
