Pierre Guerin

What Pierre Guerin does

Pierre Guerin is a French designer and manufacturer of stainless steel process equipment serving the agro-food and biopharmaceutical industries. Founded in 1949 and headquartered in Mauzé-sur-le-Mignon with its main production site in Niort, the company employs more than 600 people across France and its international subsidiaries in Spain (Burgos, est. 2018), China, and Korea. Pierre Guerin self-positions as a Top 3 global supplier of fermenters and bioreactors, and its named customer base spans dairy, winemaking, pharmaceutical manufacturing, and emerging biotech segments including precision fermentation and blue biotechnology. The company is a wholly-owned subsidiary of Equans France, itself part of the Bouygues Group, and operates under an internal 'Ambition 2027' strategic plan focused on international innovation and operational excellence.

The core product portfolio includes the PRIMO autoclavable lab-scale bioreactor/fermenter series (1–10L), the BIOPRO EVO SIP/CIP pilot fermenter series (10–30L), custom process tanks and skids, agitation and mixing systems, NEP/SEP cleaning and sterilization stations, and proprietary components including the STERI-ADD autoclavable addition valve and the patented UNIFERTEX universal fermenter with MAREX piloting software (co-developed with the CNRS Institute of Natural Chemistry under the TACSMAR project, coupling liquid and solid-medium fermentation on a single platform). Automation is delivered via the proprietary Neptune SCADA platform, with integrations to Emerson DeltaV and Siemens PCS 7, and documentation compliant with CFR 21 Part 11 and GAMP 5 for GMP environments. The company holds ISO 9001, ISO 14001 (obtained 2025), ISO 13485 (China), ASME Stamp U, DESP Module H, SELO (China), ISO 3824-2, and Siemens Solution Partner certifications.

Pierre Guerin generates revenue primarily through project-based, custom-engineered one-time equipment sales with pricing negotiated per scope, complemented by recurring after-sales service and maintenance contracts (e.g., with Amphastar France). Distribution is exclusively direct B2B — no e-commerce or self-serve channel — executed through field sales, account managers, an active international trade-show presence, and select channel partners (e.g., 1Supplier in Southeast Asia). Major reference projects include the LFB Arras turnkey installation (tripled bioproduction capacity, first commercial lots in 2025), Samsung Biologics' 256,000L bioreactor scope (2020), Amphastar's insulin facility at Eragny-sur-Epte, Laurent-Perrier (50+ year relationship), and Nyetimber (300+ installed tanks, 2025 International Wine Challenge Best Sparkling Wine).

Revenue model

1. Custom Process Equipment Manufacturing: Pierre Guerin designs, manufactures, and installs custom stainless steel tanks (cuves), process lines, skids, and fermenters/bioferactors tailored to client specifications for agro-food and biopharmaceutical industries. Revenue is generated project-by-project with one-time equipment sales.
2. Automation and Control Systems Integration: Supply and integration of automation solutions including Emerson DeltaV, Siemens PCS7, and Neptune SCADA systems as part of turnkey installations.
3. After-Sales Service and Maintenance: Pierre Guerin provides ongoing maintenance services for installed equipment, including preventive maintenance, spare parts, and technical support contracts. This represents a recurring revenue stream post-installation, as demonstrated by long-term maintenance contracts with clients like Amphastar France Pharmaceuticals.
4. Cleaning and Sterilization Systems (NEP/SEP): Design and supply of Cleaning-in-Place (NEP) and Sterilization-in-Place (SEP) stations and associated skids, sold as standalone units or integrated into turnkey process lines.
