4.5 Cubic Feet Ethylene Oxide Sterilizer: Low-Temperature Solutions
Introduction to the 4.5 Cubic Feet Ethylene Oxide Sterilizer
The **4.5 Cubic Feet Ethylene Oxide Sterilizer** is a specialized, medium-capacity unit designed for efficient, low-temperature sterilization of medical devices that cannot withstand high heat or moisture. This size is particularly suited for **Central Sterile Supply Departments (CSSD)** in mid-sized hospitals, specialized clinics, and research laboratories. It provides the perfect balance between operational capacity and compact footprint, ensuring sensitive instruments like rigid endoscopes, electronics, and plastic assemblies are safely sterilized using the reliable power of Ethylene Oxide (EO) gas, adhering strictly to global safety and sterility standards.
Working Principle and Process Flow for the Compact EO Sterilizer
Our 4.5 cubic feet EO sterilizer operates based on the principle of EO alkylation, which effectively destroys all viable microorganisms. The process is fully automated and precisely controlled. Items are loaded into the 4.5 cu ft chamber, followed by evacuation (vacuum creation), moisture injection (humidification), EO gas introduction via single-use cartridges or a tank system, an exposure period, and finally, a deep post-sterilization aeration phase. This size is engineered for a streamlined cycle that maximizes throughput while ensuring full gas removal, guaranteeing the safety of the treated devices and the operating environment.
Models of 4.5 Cubic Feet EO Sterilization Systems
- Cartridge-Based 4.5 ft³ Sterilizers :- Utilizes pre-dosed, single-use EO cartridges for safety and simplicity, ideal for hospital use.
- Bulk Feed 4.5 ft³ Sterilizers :- Connects to an external EO gas cylinder for continuous, high-volume operation in larger labs or manufacturing QA.
- Dual-Door Pass-Through Models :- Designed for sterile barrier control in CSSD departments, preventing cross-contamination.
- Cabinet-Style Low-Profile Units :- Space-saving design for easy integration into existing laboratory or clinical setups.
Key Features and Specifications of 4.5 cu ft EO Sterilizers
- Precise Temperature Control :- Maintains cycle temperature between 37°C and 55°C (99°F to 131°F) to protect heat-sensitive materials.
- Advanced Aeration Capabilities :- Dedicated aeration cycles significantly reduce EO residuals, ensuring product safety and quick turnaround.
- User-Friendly PLC Interface :- Features a modern Programmable Logic Controller (PLC) for easy cycle selection, monitoring, and data logging.
- Stainless Steel Chamber Construction :- Durable, corrosion-resistant chamber ensures longevity and safe operation under vacuum/pressure conditions.
Applications of the 4.5 Cubic Feet Ethylene Oxide Sterilizer
