Sterilization is moist heat in the form of saturated steam under pressure. The purpose is to expose each item to direct steam contact at a required temperature and pressure for a specified time to destroy microorganisms that may contaminate a product or container.
Nash utilizes vacuum in the four main types of sterilization, which are: steam sterilization, hydrogen peroxide plasma sterilization, ethylene oxide sterilization, and formaldehyde gas sterilization. Our vacuum systems optimize production with high reliability and energy efficiency.
Suction Capacity: 115 to 5,200 ACFM (195 to 8,900 m3/h)
Vacuum Range: to 1 inHgA ( to 33 mbar abs.)
Suction Capacity: 100 to 2,100 ACFM (170 to 3,600 m3/h)
Vacuum Range: to 0.8 inHgA ( to 30 mbar abs.)
Lastly, ozone gas sterilization sterilizes by oxidation, a process that destroys organic and inorganic matter. Ozone is an unstable gas but can be easily generated from oxygen. A 6% to 12% concentration of ozone continuously flows through the chamber. The penetration of ozone may be controlled by the vacuum in the chamber or enhanced by adding humidity. As completion of exposure time, oxygen is allowed to flow through the chamber to purge the ozone. Depending on the size of the chamber load, cycle time could be up to 60 minutes.
