Pierre Guerin

Bioprocessing systems: Bringing the right quality for our clients

Pierre Guerin SAS is a global supplier and market leader in design and manufacture of stainless steel upstream bioprocessing systems for fermentation and cell culture processes. With three production assets in Europe and USA (DCI-BIO, DBL), plus a technical office in China we can deliver what you need on time and to the needed quality for the market in which you operate. Our equipment is always fit for purpose, and designed precisely for you: Whether for GMP biologics, vaccines and MAB’s, to industrial enzymes, agro-feeds and bio-pesticides Pierre Guerin is the supplier you should talk to.

We are building according to your precise requirements and for us this starts with the heart of the system, the stainless steel vessel (bioreactor or fermentor). We have vessel building plants in France, Spain and through our joint-venture partner DCI-BIO in the USA. Having this capacity provides you assurance of supply continuity, plus a prime vessel built to local codes and market standards. As well as tanks certified for European and US markets, Pierre Guerin also has the SELO certificate allowing us to manufacture vessels for integrating in to systems, for clients in China.

Pierre Guerin Life Science Team brings a wealth of experience and expertise in process design, strictly developing solutions following either clients own URS and / or P&ID or developing our own solutions. In order to fully appreciate client process and to validate our understanding we can provide graphical representation of the process highlighting operational steps and concurrent or sequential events which have impact on the detailed design proposal such as primary cultivation, SIP, inactivation or CIP phasing.

Neptune™ Software is Pierre Guerin’s unique control software application designed for fermentation and cell culture process control. Developed and continuously improved for more than 10 years, it is used with the latest controls platforms of Wonderware & PLC’s, or is available in a DELTAV version. We can apply Neptune to a 3 liter autoclavable, or an 8000 liter production plant operating to GMP. The key to Neptune is its adaptability, versatility and stability. Each installation is bespoke to the client preference e.g. for data security, remote support and access, functional process, company standards and more.
