Hospital EO Sterilizer

The process operates as a cool, dry cycle at approximately 50°C. Full cycles (including preconditioning, sterilization, and aeration) generally take 12–24 hours, with an average processing window of roughly 8 hours per run depending on the load and model.

It is ideal for single-use medical and surgical items such as intravenous infusion tubing, hypodermic syringes, procedural packs, urinary drainage bags, catheters, coronary stents, cardiovascular catheters, intraocular lenses (IOLs), optical scopes, fluid tubing, and precision blades.

Chambers use high-grade stainless steel (SS 304 / SS 316) for all product-contact surfaces. Units are offered in semi-automatic versions (pneumatically controlled ball valves and push-button operation) or fully automatic PLC-HMI systems with touchscreen interfaces for unattended cycle execution. Modular designs allow sizes from 0.5 m³ to 40 m³.

Key models include:

• AETOS-2.6: 2.6 cu. ft. / 70 liters, 40 g cartridge
• AETOS-4.5: 4.5 cu. ft. / 125 liters, 100 g cartridge
• AETOS-8: 8 cu. ft. / 200 liters, 170 g cartridge

All support warm and cold cycles, include in-built aeration, require compressed air at 100 psig, and run on 220 V single-phase power (1–2.5 kW, adjustable to local voltage).

The low-temperature, moisture-free process (~50°C) combined with EO’s exceptional diffusion properties allows deep penetration into narrow channels and complex geometries. The gas alkylates microbial DNA, destroying bacteria, viruses, fungi, and spores while preserving material integrity and extending the lifespan of delicate equipment.

In-built aeration removes residual EO gas after the sterilization phase, reducing residues to safe levels (per ISO 11135 standards, e.g., <4 mg/device for most items). This ensures operator safety, product readiness, and environmental compliance.

Complete qualification documentation suites (IQ – Installation Qualification, DQ – Design Qualification, and OQ – Operational Qualification) are available as an optional add-on service upon request.

It delivers 99.9999% sterility assurance for delicate, moisture-sensitive devices, leaves items residue-free after proper aeration, supports efficient batch processing in busy hospitals, and has been a dominant low-temperature sterilization method since the 1960s. It also helps prevent microbial spoilage while safeguarding product quality.

While designed for hospitals and healthcare, they are also widely applied in pharmaceutical, nutraceutical, herbal, Ayurvedic, biotech, cosmetic, and chemical industries for sterilizing heat- and moisture-sensitive products, as well as certain packaged foodstuffs and other sensitive materials.
