Production Scale ETO Sterilizer

Production Scale ETO Sterilizer

Production Scale ETO Sterilizer or industrial eo gas sterilizer has been specially designed for sterilization of products sensitive to high temperature and to humidity (Syringes, DE fluxers, Catheters, Cartridges for Dialysis, Plastic articles, Bandages, Sutures etc.).  Sterilizer can be uses even for sterilization of powders which deteriorate by heating exposure. For the wide range of product that can be treated, such sterilizer find application in Disposable Surgical Products, Para Pharmaceutical and Pharmaceutical Industry, Laboratories, Hospital and Food Processing Industries.

Adinath Ethylene Oxide Gas Sterilizer Manufacturer can be realized in to satisfy different requirements working under pressure (1.5 kg/cm² + vacuum) with mixtures of Ethylene Oxide and Carbon Oxide (usual composition 10% ETO + 90% CO₂, 20% ETO + 80% CO₂)

Ethylene Oxide gas infiltrates packages as well as products themselves to kill microorganisms that are left during production or packaging processes. This gas, mixed with air at a ratio of at least 3% ETO gas, forms an explosive mixture. Pure ETO gas boiling point is 10.73 ºC at atmospheric pressure. Most of the time, it is mixed with Nitrogen or CO2. EO Gas Sterilizers uses to sterilize to surgical instruments and medical disposables.

The system has been designed to operate on eto+co2 combination gas cylinders. The chamber and all contact parts shall be made from S.S 304. The chamber has been provided with a single door, easy locking arrangement and silicon gasket for leak proof operation. Electronically controlled heating system to ensure uniform heating of the chamber at 50 degrees centigrade. The chamber is provided with a adequate capacity rotary vacuum pump enclosed in sturdy cabinet duly powder coated for durability. We provide four of control switches with built in indicator light to regulate evacuation, feeding of gas, fresh air inlet through filter and aeration facility. Ethylene Oxide Gas Sterilization Unit is compact stand-alone sterilizer chamber.




Exclusive Features of Industrial ETO Sterilizer

  • 20 Cubic Feet to 30 Cubic Meters chamber available.
  • Semi-Automatic and Fully Automatic (PLC based) models available.
  • Capable of operation with 10% ETO + 90% CO₂, 20% ETO + 80% CO₂ and 30% ETO + 70% CO₂ combinations.
  • Temperature range between 35˚C to 60˚
  • Flexibility in size of sterilizer as per particular object requirements.
  • Pneumatically operated automatic cartridge puncturing.
  • Double door machine also available.


Safety Features of Large Production ETO Sterilizer

  • The cycle operates in vacuum and hence is safer to operate, as there is minimum chance of leakage.
  • The electronic design provides accuracy of operation, dependability and repeatability.
  • The sterilizer can aerate items after sterilization same Machine. The sterilization-aeration process can be continuous in one chamber and hereby eliminate gas exposure during load transfers to aerators.
  • After the sterilization cycle, the chamber is purged or aerated continuously until the door is opened. This prevents a buildup of ethylene oxide from items aerating in the chamber.

Working Principle
of Ethylene Oxide Sterilization Unit

Ethylene Oxide Sterilization (Sterilization) offers various distinct advantages over the conventional steam sterilizers (sterilizers), being a DRY & COLD (operates at 50ºC ) process proves very useful in sterilization of expensive items, also it has got a unique penetration ability, so it is very useful in sterilization (Sterilization) of expensive and delicate items such as Cardiac catheters, Stents, IOL’s Tubing’s, various types of scopes, sharp surgical instruments etc., its unique mode of action, also enhances the life of several surgical accessories & disposables items thus making them perfectly reusable.

Types of Production Scale ETO Sterilizer

We are one of the leading EO Gas Sterilizer manufacturer in India. We manufacture below two types of ETO sterilizers:

  1. Semi-Automatic Operation Mode EO Sterilizer: In this type of control mode there are analog type buttons onto control panel of the machine through which machine operation procedure will be done.
  2. Fully Automatic Operation Mode EO Sterilizer: This is PLC HMI based fully automatic control mode equipment in which there is HMI mounted onto control panel of the machine through which operation procedure done.


Standard Operating Values

Sterilization Time

Usual gas exposure time is 3 to 40 hours. Sterilization time depends upon type of packaging and other process parameters.


Product Temperature

35˚C to 60˚C set temperature value is non- stop holed by force circulation of water inside the jacket and optionally inside this system is very reliable with no risk of overheating and temperature differences by steam use.


Product Humidity

40 to 70 RH 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.
