VSM-HTY500L series Ethylene Oxide Sterilizer

HTY series ethylene oxide sterilizer is a special equipment for low-temperature fumigation and sterilization of items enclosed in a sterilization room using ethylene oxide gas at a certain temperature (low temperature), pressure, humidity and a certain time of action. Ethylene oxide gas is a very active chemical disinfectant. It not only achieves broad-spectrum sterilization, but also can achieve reliable sterilization.
  • Parameters

Sterilization principle:

The ethylene oxide sterilizer produces a very specific alkylation effect through the contact between ethylene oxide and microorganisms, thereby inhibiting the normal reaction of microbial reactive groups, causing metabolic disorders and death.

 

Consumables for ethylene oxide sterilizer:

Ethylene oxide gas, ethylene oxide biological indicator, ethylene oxide indicator tape, ethylene oxide indicator inner card, ethylene oxide indicator outer card, ethylene oxide packaging bag.

 

Ethylene oxide tail gas processor:

The ethylene oxide tail gas processor decomposes the residual ethylene oxide tail gas after sterilization into non-toxic carbon dioxide and water vapor through high-temperature catalytic decomposition, which is directly discharged outdoors without the need for high-altitude emission pipelines. The decomposition efficiency is over 99.99%, greatly reducing the emission of ethylene oxide.

13. ★ Display screen
shows content
Temperature, pressure, time, current stage, operating time and alarm information, as well as the operation status of the internal hardware of the equipment. You can intuitively feel which parts of the current device are working again. It is
convenient for equipment maintenance and allows for intuitive learning of   the entire equipment’s operation process and principles.
And provide actual screen interface photos.
14. ★ Number of
doors and switch mode
Adopting a single door fan-shaped door opening and closing method, the door panel thickness is ≥ 8mm. It has high flatness, automatic locking, and

the door ring sealing strip can perfectly compact and seal, ensuring the sealing performance during vacuum pumping.

15. Structure and

material of the

cavity

 

The cavity structure is rectangular to improve space utilization. The cavity material is made of high-quality stainless steel with a thickness of ≥5mm, which has superior thermal conductivity and improves the service life and deformation resistance of the inner liner. The inner liner adopts mirror processing technology, which is beautiful without gaps and has a long service life.
16. Outer box

19. ★Sterilization
monitoring and
alarm
information
storage system
It has a sterilization record and alarm record traceability system, and the information can be directly displayed on the touch screen for relevant personnel to view at any time. Can store complete sterilization records of  no less than 8000 pot cycles
20. Data reading Upgrade the system program, read historical data during the sterilization process, and export historical sterilization records directly from a USB flash drive.
21. Sensor Built in temperature, humidity, and pressure sensors, which automatically detect the corresponding temperature, humidity, and pressure values in the sterilization room. The resolution of the temperature probe is 0.1 ℃, the resolution of the pressure sensor is 0.1Kpa, and the resolution of the humidity sensor is 0.1%
22. Heating method Adopting a five sided water jacket circulation heating system to ensure temperature uniformity within the sterilization chamber
23. Sterilizer and
dosing method
Built-in gas source: The sterilizing agent is a single-use, 100% pure ethylene oxide aerosol canister. The dosing method uses an internal, automatic puncture technology within the sterilization chamber, ensuring high safety, convenience, and stability.
External gas source: Uses the dedicated connecting pipe provided with the equipment, connecting one end to the machine and the
other end to the gas cylinder. Simply unscrew the knob when adding sterilizing agent.
Note: Both machine models are available for purchase.
24. ★ Mandatory
disability
removal system
If the traditional Chinese medicine tank has been punctured during operation and the equipment malfunctions, the system will automatically
monitor and perform forced residual discharge until all the ethylene oxide  gas inside the chamber is completely discharged. Greatly improved the safety of the device’s use.
25. Fault diagnosis Equipped with automatic fault detection, fault code content display alarm, fault sound alarm, and fault printing system. The device has a power-off memory function.
26. ★ Password
protection
Adopt password protection to prevent non operators from using it incorrectly. Some main process alarms require entering a password to clear the alarm information. After sterilization, opening the door also requires  entering a password to operate.
27. Consumable
