Combipro

cGMP Combination 3-in-1 Sterilizers

Combipro Sterilizers are designed for sterilization of almost any product or container. It is equipped with a vacuum pump for effective sterilization of dry goods, a fan system for steam-air-mixture a sterilization process, and water recirculation pipework for a water cascade sterilization process. Combipro sterilizers are ideal for contract manufacturers or process development centers to establish the optimum sterilization process for any given product or container. Combipro sterilizers can also be equipped with the necessary ports and controls to utilize gas such as H₂O₂ for the sterilization of heat sensitive containers.

3-in-1 solution for the effective sterilization of almost any product or container.

Chamber Construction

Highly polished 316L stainless steel chambers provide superior durability. The chamber door is also constructed with solid plate 316L stainless steel and held in place on all four sides by precision machined brackets for smooth travel and a tight seal against the chamber during the cycles. All chamber connections are sanitary clamp type and sloped to drain. Lubricant free door gaskets provide greater longevity and protect against particle shedding into clean rooms.

Sanitary Piping

All piping and ports in contact with the chamber are constructed of 316L stainless steel and sloped to drain with no dead legs. Sanitary clamp fittings are used for ease in removal of components. Non-proprietary sanitary valves and components are selected for their reliability and availability to reduce machine downtime.

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 cGMP-compliant and produce pure or clean steam for pharmaceutical sterilization. The generators can either be configured as stand-alone units for use as a central steam source or directly integrated into the sterilizer. BMT USA steam generators are assembled with the highest quality non-proprietary components and are available in electric or plant steam heated models.

Vertically integrated electric steam generator

BMT USA is one of the only manufacturers offering vertically integrated electric clean and pure steam generators up to 400lbs/hr with a maximum output pressure of 80 PSIG. Our vertical integration offers significant space savings while maintaining tight steam pressure control.

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.

Custom Loading Equipment

BMT USA manufactures stainless steel loading equipment in standard or custom designs to accommodate loads of any size, shape or weight. Our smaller chamber sizes can be equipped with wire or perforated shelves and loading racks, while larger chambers can be equipped with carts and transfer trolleys.

Large pit-mounted chambers include options for tracks and rub rails that can be designed to work with the wheel configuration of your existing equipment. Carts with drop down wheels are available for rooms with limited space.

Pre-Vacuum with Drying

Effective sterilization of porous and wrapped goods: filters, linens, rubber stoppers and products that are unaffected by vacuum.

The load is preconditioned with alternating vacuum and steam pulses, then heated to an exposure temperature between 110°C and 135°C. The exposure temperature is maintained for a specified period, after which rapid drying begins with fast exhaust and pulling a deep vacuum.

For loads where trapped moisture can be difficult to remove, air pulses can be added to the drying phase. The air pulses can also be heated to further accelerate the drying.

Gravity Air Removal with Ramped Exhaust

Sterilization of glassware, instruments, waste and liquids in open containers.

Steam is introduced into the chamber, displacing air and forcing it out through a drain vent. Once the air is fully removed, the load is heated to an exposure temperature between 110°C and 135°C. The exposure temperature is maintained for a set period to achieve sterilization. At the end of the sterilization phase, the steam is slowly exhausted from the chamber, allowing the load to cool back to ambient temperature.

Gravity Air Removal with Jacket Water Cooling

Sterilization of liquids in vented or loosely sealed containers that are heat or pressure sensitive.

At the end of the sterilization phase, cooling begins by injecting air into the chamber at a pressure equal to that inside the product container to prevent damage or deformation. To accelerate cooling, cold water is circulated through the chamber jacket. This lowers the temperature of the chamber walls, creating a temperature gradient that draws heat away from the load. As heat transfers from the load to the cooler chamber surfaces, the overall cooling process is sped up while maintaining controlled conditions that protect the integrity of the product and its container.

Steam-Air Mixture

Terminal sterilization of liquids in heat or pressure-sensitive containers

Pure steam is pumped into the chamber while being injected with compressed air at a preset differential over-pressure. The steam and air are circulated and mixed by internal fans, rapidly heating up to an exposure temperature between 110°C up to 135°C. The exposure temperature is maintained for a specified period, after which the fans begin blowing cool air across the load.

During the cooling phase, a support pressure is maintained to prevent damaging the product containers. At the end of the cycle, the load leaves the chamber dry and ready for further handling or labeling.

Hot Water Cascade

Rapid terminal sterilization for liquids in sealed containers that are heat or pressure-sensitive

Purified water is circulated by a high capacity pump through an external heat exchanger that is heated by plant steam. The water is then evenly distributed through a perforated tray over the load. The efficient heat transfer properties of water allows for rapidly heating the load.

Compressed air at an over-pressure is simultaneously injected into the chamber to compensate for the rising temperature and pressure that builds inside the product containers, preventing damage or deformation.

At the end of the cycle, the water is cooled by an external heat exchanger using cooling or chilled water. The cooled circulating water is continuously sprayed over the load, quickly bring the temperature back to ambient.
