Ventipro

cGMP Steam-Air Mixture Terminal Sterilizers

Ventipro steam-air mixture sterilizers provide fast, safe and effective terminal sterilization of liquids in open, sealed or heat sensitive containers. Pure steam is utilized inside the chamber for heating the liquids and over-pressure filtered air is injected into the chamber to compensate for the rising temperature and pressure that builds inside the liquid container. Internal fans mix the chamber steam and air to ensure there are no cold pockets and to provide uniform temperature distribution. Rapid heating and cooling is achieved utilizing convection principles. At the end of the cycle, the product leaves the chamber dry and ready for labeling.

Engineered for efficiency, reliability & serviceability

High Performance Fans

High performance fans intensify the streaming of the steam-air mixture through the chamber and around the load. The fan wheel and all components mounted inside the chamber are constructed of 316L stainless steel. The motor is installed outside the chamber and connected to the fan wheel with a unique sealing system that simplifies inspections and maintenance.

Chamber Construction

Ventipro sterilizers are equipped with highly polished chambers made entirely of 316L stainless steel for superior durability. The chamber door is also made from solid plate 316L stainless steel. Precision machined door brackets for retaining the door on all four sides ensures smooth travel and improved security during sterilization cycles. All chamber connections are sanitary clamp type and sloped to drain. Lubricant free door gaskets last longer and eliminate particle shedding into clean rooms.

Validation

Validation is a critical concern when purchasing a cGMP sterilizer, so special attention has been given to the documentation and repeatability of each system. Every BMT USA sterilizer is subjected to rigorous pre-validation testing at our facility and shipped with an extensive documentation package to help minimize the time required for onsite validation. IQ/OQ protocols and on-site execution options are also available.

Repeatability

The primary use of cGMP sterilizers is for production in pharmaceutical and biotech facilities where repeatability is critical. All BMT USA cGMP sterilizers utilize high-grade vacuum pumps, the highest quality instrumentation, and industry-standard PLC control systems to ensure repeatable cycles regardless of changing environmental conditions. Temperature distribution within the chamber is better than +/- 0.5°C

Clean Steam Source

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

Vertically integrated electric steam generator

BMT USA is one of the only manufacturers that can offer 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.

Control System

Industrial-grade Allen Bradley or Siemens PLC control systems provide superior operational reliability and cycle repeatability. The control systems are developed under the latest GAMP (Good Automated Manufacturing Practices) guidelines to ensure system reliability and ease in validation. The control system is also supported with a comprehensive documentation package.

The control system can configure and store 20 sterilizing cycles, which are accessed via a large touch screen operator interface terminal. In double door units, operator interface terminals are mounted on both the load and unload side of the sterilizer. All sterilizer functions are accessed through these screens and are secured by multi-level authentication. If electronic data storage is desired, the control system can be provided with 21 CFR part 11 compliance. Printers and recorders can also be equipped for physical data storage on paper.

Key Features:

Sanitary Stainless

The chamber, chamber door, sanitary piping and fittings are all constructed of 100% 316L stainless steel.

Regulatory Compliance

Designed and built in compliance with US FDA cGMP, Good Automated Manufacturing Practice (GAMP) and US FDA CFR 21 Part 11.

Rapid Heating & Cooling

Faster heating and cooling times than conventional sterilizers with precise temperature distribution.

Energy Efficient

The chamber and all piping are fully insulated to help reduce utility consumption.

PLC Controls

Industrial-grade Allen-Bradley or Siemens PLC-based control systems deliver repeatable operation.

Non-Proprietary

Fully constructed with high-grade non-proprietary components for improved reliability and serviceability.

Lubricant-Free Door Gasket

Lubricant-free door gaskets provide greater longevity and eliminate particle shedding into clean rooms.

Easy Maintenance

Unique sealing of the fan shaft allows for ease in inspection and maintenance.

Ventipro Terminal Sterilization Cycles

Ventipro sterilizers can be programmed with steam-air mixture terminal sterilization cycles 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.

Steam-Air Mixture 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 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.
