Aquapro

GMP Water Cascade Sterilizers

Overview

Aquapro Water Cascade sterilizers provide fast, safe and effective terminal sterilization of liquids in sealed or heat sensitive containers. High capacity water circulation pumps and large diameter piping ensures high water flow rates and faster heating and cooling of the load. The recirculating water is heated and cooled by external heat exchangers. The heat exchanger is heated by plant steam and cooled by softened water and has no direct contact with the recirculating water. Therefore, pure steam is not required in this process. The recirculating water is directed to a perforated tray which evenly distributes the cascading water over the product. Due to the high flow rate of the recirculating water, very even heat distribution is realized.
  • Fast heating and cooling for gentle sterilization of heat-sensitive loads
  • Ideal for sterilization of liquids in sealed containers
  • No pure steam required as water is heated indirectly by plant steam
  • Allen-Bradley or Siemens PLC control systems
  • High capacity recirculation pump for even temperature distribution
  • External heat exchangers for heating and cooling of the recirculation water
  • Perforated tray for water distribution with holes on the front, back and sides to evenly heat the door chamber surfaces
  • 316L stainless steel chamber and sanitary piping

Vertically Integrated Electric Clean Steam Generator Option

In addition to vertically integrated steam-to-steam generators, BMT USA is one of the only manufacturers also offering vertically integrated electric clean and pure steam generators up to a 400lb/hr capacity with a maximum output pressure of 80 PSIG. The vertical integration offers significant space savings while maintaining the same tight steam pressure control within +/- 2 PSIG of the set point.

Engineered Features

BMT USA offers a range of features that enhance the efficiency, reliability, and serviceability of our sterilizers. Vertical and horizontal precision machined sliding doors are exceptionally smooth and provide a safer environment for operators. Door gaskets that reliably operate without the need for lubrication reduce maintenance and prolong life span. The chamber jacket design utilizes a unique beam construction that provides a complete envelope around the chamber. PLC-based control systems are intuitive and simple to operate, while providing the necessary sophistication for maximum flexibility and ease of validation.
Perforated trays for Aquapro Water Cascade Sterilizers

Perforated Trays

Aquapro sterilizers are equipped with perforated trays that evenly distribute the recirculating water across the entire load. Additional holes on all sides of the tray distribute water throughout the chamber and door to ensure they are heated to the same temperature as the load, allowing for even heat distribution.

Aquapro Sterilization Cycles

Aquapro sterilizers are programmed with a hot water cascade sterilization cycle with configurable parameters for each cycle phase. The programmed cycle recipe is stored in the sterilizer’s control system memory and is recalled and started with the touch of a button on the operator interface. All recipes are also protected from unauthorized changes via a multi-level authentication system.

Hot Water Cascade Cycle

The cycle begins with filling the chamber to a predetermined level with purified water.  The water is circulated by a high capacity pump through an external heat exchanger that is heated by plant steam.  The water is distributed through a perforation tray onto the product.  Due to the efficient heat transfer of the water, the product is heated rapidly.  Compressed air at an over-pressure is injected into the chamber to compensate for the rising temperature and pressure that builds inside liquid containers when heated.  At the end of the exposure step, cooling begins.  The circulating water is cooled by an external heat exchanger that is cooled with cooling or chilled water.  The load is quickly cooled to ambient temperature by continuously being sprayed with the circulating water. This method of sterilization is the fastest method for sterilization of liquids in sealed containers.

Sterilizer Steam Source

BMT USA steam generators are constructed to cGMP guidelines and designed to provide pure or clean steam to meet the requirements of your sterilization application. The units can be configured as stand-alone units to be used a central source of steam for multiple units, or directly built into the sterilizer for a fully integrated solution. BMT USA steam generators utilize high grade non-proprietary components and can be electrically heated or heated by plant steam.

Electric Heated Steam

BMT USA electric clean steam generators are equipped with an ASME pressure vessel constructed from 316L stainless steel. The heating elements require three-phase voltage that can be specified at time of order. The units are equipped with an automatic blow-down system that carries impurities to drain. Feed water booster pumps are available when feed water is not available at the required pressure.

Steam-to-Steam

BMT USA steam-to-steam generators utilize plant steam as the heating source to produce clean steam. The tube and shell heat exchanger is made from 316L stainless steel and can be built in single-tube or double-tube configurations. The evaporator utilizes a wetted design that minimizes the temperature difference between the feed water and the heating steam, reducing stress on the evaporator tube sheet.

Sterilizer Loading Equipment

BMT USA manufactures stainless steel loading equipment in standard or custom designs to accommodate any type of load. Our smaller chamber sizes can be equipped with wire or perforated shelves or loading racks, while large chambers can be equipped with loading carts and transfer trolleys. Large pit-mounted chamber include options for tracks and rub rails that can be designed to work with almost any type of wheel configuration on existing equipment. Carts with drop down wheels are also available for rooms with limited space.
