2 Cubic Feet EO Gas Sterilizer

The sterilizer uses a controlled mixture of ethylene oxide gas with inert diluents such as carbon dioxide or nitrogen. EO alkylates the DNA and proteins of microorganisms (bacteria, viruses, fungi, and spores), preventing them from reproducing. The process includes vacuum air removal, conditioning (humidification and heating around 30–60°C), EO exposure, and aeration to remove residual gas.

EO sterilization operates at a gentle ~50°C without steam or high heat, preventing thermal distortion or moisture damage to delicate items. It offers superior penetration into complex lumens, multi-channel tubing, and tightly packaged materials, making it suitable for heat- and moisture-sensitive devices that cannot withstand autoclave conditions.

It effectively sterilizes infusion sets, disposable syringes, surgical packs, catheters, urine collection bags, cardiac catheters, vascular stents, intraocular lenses, diagnostic scopes, microsurgical tools, and similar heat-sensitive medical products. It is also used for certain agricultural and food products such as spices and packaged grains.

Two main models are offered: a Semi-Automatic version with analog push-buttons and manual controls, and a Fully Automatic version with PLC and touch-screen HMI for hands-free operation, digital batch tracking, and precise parameter control.

The relevant model (AETOS–2.6) has a working capacity of approximately 2.6 cubic feet (70 liters), chamber size around 12″ (W) × 12″ (H) × 32″ (D), uses a 40-gram sterilant gas cartridge, supports both warm and cold cycles, includes built-in aeration, requires compressed air at 100 psig, and runs on 1 kW power at 220 V single-phase 50 Hz (adjustable to local voltage).

All product-contact components are fabricated from premium AISI 304 / 316 stainless steel for excellent corrosion resistance and easy sanitation. The chamber is typically double-walled with insulation for safety and efficiency.

It features an explosion-proof design, leak detectors, automatic shutoffs, pneumatically actuated ball valves, and compliance with relevant standards such as ATEX and ISO 11135. The inert gas diluent further reduces flammability risks.

The cycle consists of air removal (vacuum), conditioning (humidification and heating), EO exposure (typically 1–2 hours dwell), and aeration/purge with fresh air flushing. An in-built aeration facility is provided to remove EO residues efficiently.

It is used in pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, cosmetic, and chemical industries, as well as in small-to-medium healthcare facilities needing reliable low-temperature sterilization of sensitive medical devices and supplies.
