4 CFT Ethylene Oxide Sterilizer

EO gas sterilization operates at a gentle temperature around 50°C without steam or high heat. This protects delicate materials from thermal distortion or moisture damage while providing superior penetration into complex geometries, lumens, packaging, and multi-channel devices that cannot withstand conventional steam autoclaves.

It effectively sterilizes disposable syringes, infusion sets, surgical kits, catheters, urinary drainage bags, endoscopes, cardiac implants, surgical meshes, electronic components, plastic tubing, textiles, intraocular lenses, vascular stents, and similar heat-sensitive products. It is also suitable for certain agricultural commodities such as spices, dried nuts, cereals, and herbal ingredients.

The AETOS–4.5 model offers a working capacity of 4.5 cubic feet (125 liters), chamber dimensions such as 12″ (W) × 12″ (H) × 54″ (D) or 15″ (W) × 15″ (H) × 36″ (D), uses a 100-gram sterilant gas cartridge, supports warm and cold cycles, includes built-in aeration, requires compressed air at 100 psig, and operates on approximately 2 kW power at 220 V single-phase 50 Hz (adjustable).

The process involves vacuum air removal, conditioning (humidification and heating), EO gas exposure that alkylates microbial proteins and nucleic acids, and subsequent aeration/purge to remove residual gas. The gaseous sterilant diffuses thoroughly through packaging and complex device structures to achieve the required sterility assurance level.

All internal contact surfaces and critical pathways are made from high-grade AISI 304 or 316 stainless steel for corrosion resistance and chemical inertness. The system includes pneumatically actuated ball valves, robust automated controls, and is engineered for safe handling of EO gas in operator-assisted environments.

A standard cycle is optimized for efficient gas exposure and evacuation, typically completing within an approximate 8-hour timeframe. Built-in aeration is provided to effectively remove EO residuals after sterilization.

Yes. Semi-automatic models use analog push-buttons and electromechanical switches for operator-controlled operation. Fully automatic models feature PLC controls with an intuitive touchscreen HMI for hands-free recipe execution, automated phase tracking, and precise parameter management.

It is widely applied in the pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, cosmetic, and chemical industries, as well as in healthcare settings requiring reliable terminal sterilization of heat-sensitive consumables and devices.

Full IQ, OQ, and DQ validation protocols and documentation packages are available upon request to meet strict regulatory audit requirements. The design supports achievement of targeted sterility assurance levels while preserving the integrity of delicate polymers and devices.
