E.T.O. Sterilizer

REMARKABLE FEATURE:-

• Fully Automatic
• Chamber Volume: 310x310x1200 mm = 120 L (4CF)
• PLC/HMI

SPECIFICATION:-

• Stabilizing:PLC check the door condition if its close then process starts. When all temperature sensors reach to the stabilizing temperature set point and start controlling temperature for whole cycle.
• Stabilizing Time:After reaching stabilizing Temperature, system holds the process for stabilizing time.
• Pre vacuum:After Stabilizing Time Vacuum pump start until vacuum reach to the set point.
• Pre vacuum Hold:When Vacuum reach to the set point vacuum hold time start after vacuum hold time PLC check the current pressure value with allowable vacuum tolerance value if its fail then system abort & Hooter will start due to leakage found in process. If it's ok with tolerance then further process continue.
• RH injection:After Vacuum hold time RH injection (Steam inlet) starts for 5 sec.
• RH Dwell Time:When steam enter to chamber RH Dwell time start after Dwell time PLC check the humidity level with set point if its fail then again RH injection will start followed by RH dwell time. If Humidity level reach to set point process continue to next phase.
• ETO Gas Pressure:After RH dwell time PLC start ETO (Ethylene Oxide) inlet to chamber until it reach to set point.
• ETO Exposure Time:After ETO inlet Exposure time start and PLC always check Current Pressure value with Gas pressure drop tolerance during whole exposure time. If its fail exhaust valve & hooter will open and PLC abort the cycle due to leakage found in process.
• ETO Exhaust:If ETO Exposure is above the atmospheric pressure then Exhaust valve open and chamber lose its pressure to atmospheric pressure. If ETO Exposure is below the atmospheric pressure then vacuum pump get started to the set point (Pre vacuum) and Air break valve will open until atmospheric pressure.
• Post Vacuum:After ETO exhaust vacuum start until post vacuum set point.
• Air Break:After Post Vacuum Air break valve will get open until chamber pressure reach to the Atmospheric Pressure.
• Post vacuum & Air break process repeat for No of pulse is set in parameter.
