What comessa does

Comessa S.A. is a privately held French industrial equipment manufacturer, founded in 1920 and headquartered in Strasbourg, that designs and builds custom thermal processing systems for divided solid materials — powders, crystals, granules, pellets, and tablets. Its core technology portfolio covers six equipment families: static and vibrating fluidized beds (including high-temperature variants up to 950°C with indirect heating and controlled atmosphere), direct and indirect rotary tube dryers/coolers, band and conveyor dryers for fragile or sticky products, pneumatic flash/rapid dryers for fine materials, and paddle granulators for fertilizer pre-granulation. These units are engineered as either standalone equipment or as fully integrated turnkey drying plants with ancillary air preparation, dust collection, instrumentation, and material handling systems, designed to international codes including PED, ASME, EN, and ISO standards.

The company sells engineering-driven, project-based custom solutions directly to enterprise clients across nine verticals — chemicals, fertilizers (NPK, DAP, AN, CAN), agri-food, batteries (including lithium carbonate), catalysts, minerals, polymers, sugar, and environment/recycling — with a particular concentration of more than 260 plants in the global sugar industry across 30 countries. Comessa supports its sales process with a 1,200+ m² in-house test laboratory and full pilot-scale equipment covering all commercialized technologies, enabling feasibility and semi-industrial validation before order commitment, and uses 3D CAD, CFD simulation, and finite element analysis as standard design tools.

Commercially, Comessa operates a direct enterprise field-sales model with no disclosed channel partners, generating revenue primarily through one-time equipment sales of custom-engineered systems plus ancillary professional services — engineering studies, commissioning, training, on-site technical audits, and spare parts supply. Pricing is project-specific and quote-based and not publicly disclosed. The company holds ISO 9001/14001/45001/20000/26000 and SA 8000 certifications, has maintained EcoVadis Silver status for five consecutive years, and has participated as an engineering partner in EU research consortia (SOLPART, NEXT-CSP, CSP2) developing high-temperature solar-thermal reactor and concentrated solar power technologies. Revenue, headcount above the disclosed 11–50 band, and ownership details are not publicly disclosed.

Core offering

Comessa designs, manufactures, and commissions custom-built industrial equipment for the thermal treatment of divided solids, including fluidized beds (static, vibrating, high-temperature) and rotary tubes (direct and indirect). The company delivers complete drying, heating, cooling, calcination, roasting, and granulation plants for industries such as chemicals, fertilizers, batteries, minerals, agri-food, and sugar, supported by a test laboratory for pilot trials and by after-sales technical assistance and spare parts.

Product overview

COMESSA offers a comprehensive portfolio of industrial thermal treatment equipment for divided solids (powders, crystals, pellets, granules, tablets) with six core product categories: Static and Vibrating Fluidized Beds (including High Temperature variants up to 950°C), Rotary Tubes (direct, indirect with heat exchanger, and wall-heated), Band/Belt Dryers, Flash/Rapid Dryers, and Paddle Granulators. These equipment types are complemented by full custom-built drying plant solutions that integrate air preparation, dust removal, instrumentation, and product handling systems. COMESSA also provides engineering and design services (including 3D CAD, CFD simulation, and finite element analysis), technical assistance, spare parts, and an on-site 1200+ m² test laboratory for feasibility and semi-industrial testing. The company serves nine industry verticals: Chemicals, Fertilizers, Agri-Food, Batteries, Catalysts, Minerals, Polymers, Sugar, and Environment/Recycling.

Partnerships

Three partnerships are on record, tiered core and minor.

• SOLPART Project ConsortiumcoreStrategic or Co-development PartnerCOMESSA participated in the SOLPART European research project (Agreement No. 654663) focused on developing high-temperature solar-heated reactors for industrial production of reactive particles. COMESSA was responsible for the design and manufacturing of the pilot unit for the CNRS (Centre National de la Recherche Scientifique) study. The project aimed to develop solar high-temperature processes (800-1000°C) operating 24 hours/day for treatment of particles in non-metallic mineral industries.
• NEXT-CSP Project ConsortiumcoreStrategic or Co-development PartnerCOMESSA participated in the NEXT-CSP European research project (Agreement No. 727762) focused on high-temperature solar thermal power plants with particle receivers and direct thermal energy storage. COMESSA was responsible for P&ID (Piping and Instrumentation Diagram) of instrumentation/valve lists and provided engineering consulting for the pilot plant, leveraging experience from the CSP2 project.
• CSP2 Project ConsortiumminorStrategic or Co-development PartnerCOMESSA previously worked on the CSP2 project (Agreement No. 282932), which provided foundational experience for the NEXT-CSP project involvement. CSP2 focused on concentrated solar power technology development.
