E.O Gas Sterilizer (CHW-EO55)

Product Detail Information

CHW-EO55 is a mixed gas E.O sterilizer and has a large chamber capacity of 55 liters, which is big enough to sterilize surgical instrument in all sizes and lengths. With MICRO-CONTROLLER attached to the FRONT DOOR, this compact sterilizer looks quite small from outside but it has a very practical chamber.
Mixing Gas .EO(20%) + CO2(80%)/Standard .EO(12%) + CFC(88%)

DOOR INTERLOCK SAFETY SYSTEM is a mechanical safety device, which does not allow the door to be open when the chamber is pressurized. This device is used in order to protect users from possible risk.

The air introduced into the chamber during the cleaning process comes through the air filter(BACTERIA & AIR FILTER) that has the capacity of filtering our 99.97% of the particles in the size of 0.3um and it can protect the sterilized material from being contaminated. The microprocessor indicates the time to change air filters on the monitor.

The gas supply system inside the chamber supplies gas vaporized from liquefied gas. CHW-EO55 adopted a pulse vaporizing system that completely vaporizes the liquefied gas so that no residual gas reactants remains in the chamber.

In this product, the AIR REMOVAL SYSTEM uses a Teflon sealed piston vacuum pump with wtrong power and excellent endurance.

The number of times when EO gas was used is all stored in a memory chip and is displayed on the MONITOR when the power is turned on. The device is programmed in such a way that allows a user to check and confirm the time to change the EO gas, before activating the sterilizer.

A program for cleaning only process is included in the system that enables the user to set the time and temperature to run the cleaning process any time when necessary.

The MICROPROCESSOR does automatic control of the whole sterilization process and the SELF-TEST program displays, on the LCD MONITOR, errors and unstable status of the system while sterilization is under way.

This E.O gas sterilizer is designed for user's convenience and patient's safety preferentially.
