WaSter® Series

WaSter® by Angelantoni Life Science is a new generation of compact equipment designed to eliminate the risk of biological transmission through the combined treatment of shredding and sterilization with saturated steam. The waste shredding and sterilization process ensure a final SAL (Sterility Assurance Level) of 10-6, as required by the standards for biological safety classes for the treatment of waste presenting a high individual risk that can also be transmitted via aerosols ('biohazard').

WaSter® consists of a vertical storage chamber, with a loading door, and a pass-through sterilization chamber, with double doors, for collecting the treated waste. WaSter® can operate autonomously with a production capacity of 50 kg/h.

The receiving trolley is introduced from the dirty side of the sterilization chamber and the waste is loaded into the vertical chamber. The three doors are closed and automatic treatment begins via touch screen or remote control (optional). The first stage is waste shredding, the second stage is sterilization in which the shredded waste comes into contact with saturated steam. The last step is the drying of the shredded material.

WaSter® is configured to perform the following treatments and cycles:

  1. 134°C treatment for 'biohazard' solid waste
  2. 134°C treatment of 'biohazard' liquid waste in open containers
  3. steam penetration test cycle (Bowie&Dick Test)
  4. automatic electronic steam penetration test cycle according to EN 285 (Optional - Electronic/automatic Bowie&Dick)
  5. vacuum test cycle
  6. open cycles: possibility of programming 100 new treatments
