What Lemer Pax does
Lemer Pax SAS is a privately held French designer and manufacturer of radiation protection equipment, founded around 1969 and headquartered in Carquefou (Nantes metropolitan area), France. The company sells shielded enclosures, hot cells, automated preparation-injector systems, radiation protection cabins, and shielding materials to hospitals performing nuclear medicine, radiopharmacy and interventional cardiology procedures, to radiopharmaceutical CDMOs and research centers, and to nuclear-industry and non-destructive-testing clients. Its proprietary product lines — Posijet®, Theranojet®ARA, Epijet®, Cathpax® AIR/AF, Easypharma®, Novashield®, and the DS-75 / REP-75 / RS-75 / DOM hot-cell family — are designed and manufactured in France under ISO 9001, ISO 13485, and CE Mark certifications, supported by 200 registered patents and licenses between 2008 and 2024 and a 7% R&D budget.
The company operates an enterprise field-sales model with quote-based, multi-year contract pricing and a high proportion of custom 'sur-mesure' solutions, complemented by distribution partnerships with Medisystem, ICU Medical (Plum 360 pump in France), CCNuclear (Lemer Pax America JV), and Moltek (Middle East and Central Asia). Revenue is generated through hardware sales, custom engineering projects, and maintenance and support services, with recent strategic emphasis on radioligand therapy (Lu-177-PSMA), commercial CDMO (IRE in Fleurus), and US market entry. Lemer Pax has 190 employees including 20 R&D staff and serves customers in 76 countries; founder-family leadership under Pierre-Marie Lemer remains in place.
