MPDS^®EVO

The implementation of a photochemical process from the laboratory to production scale is impossible without the prior investigation of fundamental photochemical process parameters. By using the MPDS^®EVO in miniplant technology at the lab it is now possible to determine all photochemically relevant process parameters, such as the space-time yield, reaction kinetics, selection of suitable solvents, concentration and spectral absorption coefficient, optical path, etc. in a structured and reproducible way under supervision. In addition, different photochemical process methods can be compared and evaluated side by side. Only with the obtained fundamental process parameters, the feasibility and cost of photochemical processes can are assessed
(CAPEX / OPEX). By use of the unique easy-up-scaling radiation sources with stepless power regulation, which are part of the MPDS^®EVO system, it is possible to select the correct application optimized industrial photoreactor out of the portfolio of Peschl Ultraviolet GmbH and thus, it is easy to transfer the process into commercial scale. Photochemical reactions which are already performed in industrial scale can be traced and afterwards optimized in detail in the laboratory (down-scaling). Using the reaction optimized and safe photoreactors of Peschl Ultraviolet, you are getting a highly efficient photochemical production plant with exceptional productivity.

Use of protective casing is compulsory so as to comply with the legal industrial safety requirements. It is completely safe to perform photochemistry in the photonCABINET (safety cabinet) and yet still practical. Special attention was paid to simple sampling and the uncomplicated insertion of sensors and actors such as stirring tables and dosing pumps. For example, encoded connectors ensure the correct electrical connection. The standard photoreactor systems are supplied fully wired and can be used immediately. With a footprint of 472 x 475 mm only, the system takes little space on the bench and still fits into a standard fume hood.

Photoreactors, cladding tubes and radiation sources are compatible with each other in the modular system and are therefore interchangeable. Application-optimised photoreactors can be exchanged cost-efficiently, while the lamps and cladding tubes can be retained. By freely positioning the radiation sources in the cladding tube using the innovative high-tension mechanism, it is possible to use the components in a range of different sized photoreactors. An extensive product range of perfectly matching components, such as chemically resistant process and metering pumps, agitators, various sensors – e.g. for flow, temperature, pH / redox – as well as jacketed vessels are available in the modular system. Thus we offer a customizable and expandable process development system that you can use right away.

Alongside cold radiation sources, a sophisticated, modular cladding tube system is available for the thermal decoupling of the lamp from the reaction medium. The innovative MPDS^® screwing system prevents glass fastening elements from caking and can be applied with a maximum pressure of 0.5 bar. The diameters of the cladding tubes are optimised for photochemical reactions. Easy to clean thanks to fully demountable cladding tubes instead of double wall sleeves that are merged together, perfectly suited to CIP cleaning.

In addition to our turnkey process development systems, profound, scientifically substantiated consultancy services in the field of applied photochemistry might be required as a service. Together with our cooperation partner 'Oliveros Consulting' (Prof. E. Oliveros and Prof. A.M. Braun), we are able to transfer comprehensive and detailed knowledge of photochemical process technology and offer the assistance during your process development phase on advisory basis upon request.
