MULTITRON – Multiple-Effect Distillation UnitsWFI from the pharmaceutical water specialist

MULTITRON is a unique designed multi-effect distillation unit with a superior energy efficient performance and most reliable WFI water quality. Employment of the best tech-nologies in multiple-effect distillation, an energy-saving design with 1 up to 8 effects, plus years of experience and specialist know-how are guaranteed.

BWT Pharma & Biotech designed a unique double-tube-sheet evaporator, which is integrated into each of the columns without any fixed points. The entire heat exchanger is sub-mersed below the preheated feed water, thus eliminating the chance of scaling or rouging and using all energy which is led into the shell-side of the evaporator.

Our MULTITRON distillation units meet all special pharma-copoeia specifications such as European and the USP regulations.

BWT Pharma & Biotech offers reliable and most energy efficient multi-effect equipment for the production of Water for Injection (WFI) and Pure Steam. Our systems comply with the latest cGMP requirements and include features to integrate it into an overall system. The state-of-the-art control package complies with GAMP requirements (option) as well as with an intuitive operation via touch-screen panel. Each system is fully equipped to be hooked up to an overall building manage-ment or 21 CFR Part 11 data storage system.

High standards with optional features

MULTITRON distillation units consist of 1 up to 8 columns. Continuous monitoring and documentation of the distillate via control system guarantees automatic rejection of, for example, distillate with excessively high conductivity or unacceptable temperature.

MULTITRON distillation units are characterized by customer-oriented performance features:

  Compact design. All parts are mounted in a stainless-steel frame

  No moving parts, thus minimal maintenance

  All parts in acid-resistant stainless steel

  Feed water pump and feed water pre-heater integrated in the frame

  Low steam velocity

  Pure steam can be taken from the first column either when producing WFI or independently (COMBITRON version)

  Unique three phase droplet separation system

  Automatic sterilisation optionally available

  Standard control components

  Standard fittings, measuring and control engineering

  User-friendly control panel with easy-to-read display and continuous indication of the process status. Stan-dard in all BWT units and skid mounted systems

All parts in contact with the product are made of high-quality stainless steel (AISI 316 L) 1.4404/1.4435 and all joints have an aseptic TC connection. Calculation, design and production of the pressure vessels are based on the manu-facturing and inspection guidelines of PED or ASME rules.

VAPOTRON – for Efficient Pure Steam Production

BWT Pharma & Biotech offers both separate pure steam ge-nerators (VAPOTRON) for the production of sterile, pyrogen-free steam as well as combined systems (COMBITRON) for pure steam and WFI in a single unit.

VAPOTRON meets the strict requirements for dry, pyrogen-free pure steam for applications, such as:

  Sterilization in place (SIP) of equipment

  Sterilization of piping systems

  Operational heating source for GMP sterilizers

  Sealing of GMP gaskets such as Biotech fermenters

  Air humidification of clean-rooms

For all these purposes BWT Pharma & Biotech offers the fully cGMP complying pure steam generators VAPOTRON. Pure steam for steam sterilizers/autoclaves which must comply to EN 285 requirements can be equipped with a degasifyer mounted in the same skid.

Higher capacity – fully automatic

The basic principle of a VAPOTRON pure steam generator is the same as the 1st column of a multiple-effect distillation unit, using the same technology to have the most efficient production and also the most reliable pure steam pressure into the pure steam network as possible.

| 5 BWT – For You and Planet Blue.

A combined pure steam and distillation unit simplifies the provision of ultra-pure media: instead of using two units, pure steam and Water for Injection (WFI) can be generated with COMBITRON in a single unit. This is made possible by the use of a specially designed first column with a larger diameter and of the natural circulation principle.

The media can be produced simultaneously or separately with an output of about 1,000 kg of pure steam and up to 4,000 litres of WFI per hour. The ratio of pure steam to WFI can be adjusted in the range 2:1 to 1:4 to match individual project requirements. Customer-specific versions with higher outputs and with individual configurations are available.

Reduced investment costs – less footprint

Since the COMBITRON produces two ultra-pure media from a single unit, the investment costs for the system and its periphery are reduced by up to 30 per cent, and the combined unit requires considerably less space than two separate units.

COMBITRON – The Perfect Combination

| 6 Multitron – Vapotron – Combitron

MULTITRON distillation units, VAPOTRON pure steam gene-rators and COMBITRON skids, equipped with a Siemens or similar control, can be individually programmed for specific requirements. An additional Touch-Screen Panel allows simultaneous operation and process monitoring of the whole distillation unit. Production and process data can be scanned, documented and updated at any time.

Fully automatic production of the distillate guarantees, as recommended by the FDA, rejection of the first product after re-start-up.

Quality control is then performed at all project steps.

  Design review

  Receiving inspections

  Software review

  Pre-inspections of control cabinet

  Manufacturing inspections according to ISO 9001 procedures

  Factory Acceptance Testing (FAT)

  Site Acceptance Testing (SAT)

Validation, quality control and documentation

In the beginning of a project a Quality & Project Plan is set up to show the quality control in the project, together with scope, responsibilities etc. This document is given to the customer for approval and ensures a well working project.

MULTITRON, VAPOTRON and COMBITRON are validated according to FDA, cGMP, GAMP, USP and Ph. Eur. re-quirements. BWT Pharma & Biotech also follows the ISPE Engineering Baselines for Water and Steam Systems, and Commissioning and Qualification. The systems are CE-marked according to applicable directives, such as PED, EMC, LV and the Machinery Directive.

The validation engineers accompany each project through all steps of the V-model, starting with the URS and ending with FAT/SAT before hand-over of the unit.

Our skid-mounted distillation units and pure steam generators leave the manufacturing site after a successfully executed FAT with test run checking capacities. The units can be commissioned easily and quickly and are finally validated on site to start producing WFI and/or pure steam.

Highest Level of ReliabilityBWT Heat Exchanger Designs – Repeatedly Proven through Effective Advantages

Stress-free heat exchangers

The heat exchangers are immersed completely in feed water and the heating steam at constant temperature in the entire column allows free and uniform expansion of the heat exchanger tubes and of the outer jacket. Your advantage: minimal stress within the heat exchanger and weldings. The risk of corrosion is reduced to a minimum allowing a much extended lifetime. Optimal process engineering is understood in order to avoid vibrations and thermal stress for heat exchangers and installed equipment.

Thorough testing

  Dye penetration testing of tube/tube end plate welds

  Hydrostatic testing and final inspection according PED

  Radiography of the main welds according to German rules

No tendency to scaling

Scaling is kept to an ideal minimum, particularly in the case of feed water containing silicates, as the heat exchangers are immersed completely in feed water and the tubes are continuously in the wet area.

Drainability

The BWT design allows full drainability of each column and all heat exchangers.

Large expansion area for the steam

Half the column height is available for expansion of the steam and for droplets precipitation in the upper column area.

FDA-approved double-plate tubular heat exchangers with seamless tubes

The double-plate tubular heat exchangers are supplied with seamless tubes. The FDA recommends their use wherever a medium of lower purity is at a higher pressure. For example, the 1st column, the condenser, the cooler and the pre-heater in our distillation units.

The heat exchanger tubes are then rolled into the inner tube plate and welded into the outer tube plate. Our heat exchanger design is characterized by longer service intervals, less spare parts (no gaskets) and thus, a much extended lifetime.
