ASW Series - Terminal sterilization

Superheated water sterilizers. Used to sterilize liquids in sealed or heat-sensitive containers such as: bottles, ampoules, vials, semi-open containers, bags, blister packing, pre-filled syringes, pockets, contact lenses, LPVs, and also for the pasteurization of products like blood plasma.

The sterilization program using superheated water is used mainly for sterilizing large containers, although it can also be used for other types of loads. The product is treated in counterpressure, in order to avoid deforming or breaking the container. The ASW Series offers a rapid, safe and effective terminal sterilization process for high product throughput.
Water is continuously circulated through the system and cascades over the load using spray nozzles, high capacity pump and large diameter piping to ensure high water flow rates.

Compressed air at overpressure is injected to compensate for the rising temperature and pressure that builds inside the products when heated. The cooling phase brings the product down to ambient temperature by continuously spraying the recirculating water over the load. To assist heat penetration, the load can be rotated during the complete cycle.
