With rich industry experience and knowledge, we are offering an assorted gamut of Ethylene Oxide Gas Sterilizer. This sterilizer is extensively used in disposable surgical products, para pharmaceutical and pharmaceutical industry, laboratories, hospitals and food processing industry for sterilization of powders that can be deteriorated by heating exposure. Our sterilizer is specifically designed for sterilization of products sensitive to high temperatures and to humidity.


  • Dynamically balanced fan provided for hot air circulation to achieve uniform temperature
  • Basic structure made from M.S. Heavy angles
  • Complete electric panel board with pulley and damper connection


  • Standard cycle operating pressure-1 bar to + 2 bar. This technique uses near 100% air removal from sterilization chamber those results in better temperature uniformity in the chamber because of the absence of air pockets
  • It increases the penetration of ETO gas in porous products from which removal of air is difficult
  • Vacuum drying at the end of sterilizing hold period ensures drying of the material which has been sterilized it is useful for ampoules in cassettes, small items of processing and packaging equipment entering the class 1 area and processing drums, garments, fabrics, drying, rubber bungs vessels machine parts, liquids in bottles and PVC pouches.

Standard operating values:
Sterilization Time:

  • Usual gas exposure time is 3/4 hours. Sterilization time depends on both type of packaging and other process parameters

Product Temperature:

  • 40/60 C set temperature value is non-stop holded by forced circulation of water inside the jacket and, optionally, inside the system is very reliable with no risk of overheating and temperature differences by steam use

Product Humidity:

  • 40/70 RH% Such value is obtained with sterilizer under vacuum condition to allow best conditioning of sterilization load

Gas Concentration inside the Sterilizer

  • Variable on the basis of used gas mixture and operating pressure

Typical (ETO) Sterilization Cycle:

  • Pre vacuum phase
  • Vacuum hold phase
  • Rh injection and rh hold phase
  • Gas inlet phase
  • Gas exposure phase
  • Gas exhaust phase
  • Air wash phase
  • Cycle over

Cycle Basic Phases:

  • Load of product to be sterilized Product heating by heated water circulating inside the jacket which makes heat exchange easier
  • Pre-vacuum with value that can be automatically set up to 15 Inch/Hg max
  • Vacuum leak test of the chamber before gas inlet
  • Product conditioning by humidification up to a preset value
  • Inlet of preheated and vaporized gas up to selected pressure value
