ASW Series

Pharma Grade Superheated Water Sterilizers.

Steelco’s range autoclaves using superheated water are for the terminal sterilization of injectable solutions. This sterilization method avoids damage to the processed liquid material and their containers, including heat-sensitive materials. It is used to sterilize liquids in sealed or heat-sensitive containers such as bottles, ampoules, vials, semi-open containers, infusion bags, blister packing, pockets, contact lenses, LPV’s, etc., and also for the pasteurization of products like blood plasma.

The ASW Superheated Water Sterilizer is available in several chamber sizes – chamber volume ranges from 830 to 25.000 liters (29 to 883 cu ft) – with the possibility of customizing dimensions upon customer-specific requirements. The chamber is equipped with horizontal sliding double doors, and an electromechanical device controls the movement. A gasket guarantees the door tightness in Silicon FDA compliant swallowtail pneumatically pressurized by compressed air.

The ASW Series is designed, manufactured, validated, and documented according to the latest global practices and standards to facilitate customer compliance with current Good Manufacturing Practices (cGMPs).
