We remain at your disposal for any projects you may have, offering you the best tailored solution to your requirements.
Rest assured of our full attentiveness, support and expertise.
Technical experience
With more than 100 years experience in design, engineering and project management, and over 1,500 equipment sold all over the world, COMESSA undoubtedly draws its strength from its technical expertise and workforce.
Controlled project management
As soon as an order is received, a project engineer is designated. This is the client’s main contact for the entire duration of the project. The project engineer coordinates all the tasks involved, and is assisted by our experts.
A team of specialists
We are experimented in fields as varied as industrial processes, thermal, aeraulic, mechanic, hydraulic, electricity, instrumentation and automation. This wide range of competencies enables us to supply highly technical industrial plants.
Optimized equipment design
Design of COMESSA technologies is optimized through the judicious use of cutting-edge tools and software (3D CAD modeling, computational fluid dynamics simulations, finite elements analysis, etc.).
Compliance with international construction standards
Our plants can be designed to comply with European directives, international codes, as well as the applicable standards (PED 2014/68/EU, EN 13445, ASME, CODAP, AD Merkblätter, etc; EN, ISO, ASTM, JIS norms, etc.).
Besides, we are able to propose plants in compliance with ATEX regulation as well as tringent hygiene standards equipment.
COMESSA constantly works to meet and satisfy its client requirements by proposing totally custom-built equipment that complies with their strict specifications (process environment, compliance with directives and norms, energy optimization, etc.), while respecting cost, quality and deadline constraints.
Scope of our services ranges from the supply of individual dryers to full drying plants, for autonomous operation.
These plants may include various ancillaries such as:
- Air preparation assemblies (filtration, ventilation, heating systems, conditioning units)
- Dedusting assemblies (cyclones, scrubbers, bag filters)
- Instrumentation and electrical panels (control systems, automation, etc)
- Ducting and connection pieces
- Handling the product up- and downstream of the main unit
Erection - Commissioning - Training
COMESSA offers its clients assistance with erection and commissioning of its equipment, under the supervision of qualified technicians operating worldwide.
Our services may also include training modules for users, so that the equipment can be used properly.
Expertise
As an expert in drying processing, COMESSA is able to carry out on-site technical audits in order to:
- Check and assess state of plants and propose preventive maintenance
- Optimize plants process and mechanical performances
- Debottleneck and revamp plants
- Etc.
Spare parts
COMESSA supplies spare parts for all its plants, delivering anywhere in the world.
We guarantee a prompt response to spare parts inquiries, in shortest delivery times.
COMESSA has its own test laboratory covering more than 1,200 m², thereby offering you the possibility of carrying out feasibility tests but also semi-industrial tests, for all of its equipment sold.
Through a large park of pilot units, skills and expertise of its engineers, COMESSA will be able to prepare pilot plants specifically adapted to your requirements and processes.
Our specialists will set out an experimental plan to obtain the information needed to validate the proposed solutions and thus determine the optimal size of the equipment.
Once the tests have been carried out, we will send you a full test report, together with lists of the measurements obtained and our recommendations regarding technological choices.
Main pilot plants available:
- Static fluidized bed
- Vibrating fluidized bed
- High-temperature fluidized bed
- Fluidized bed with heat exchangers
- Direct rotary tube
- Indirect rotary tube with heat exchanger
- Indirect rotary tube heated through the wall
- Band dryer
- Flash dryer
COMESSA is also able to rent out some of its pilot plants.
