Heavy industry (chemicals, petrochemicals, metallurgy, steel industry)
We regularly work in complex environments with demanding operating conditions :
- Extreme conditions : corrosive fluids, non-Newtonian fluids, atypical temperatures or pressures
- Custom-designed heat exchangers for specific or critical processes
- Waste heat recovery projects, particularly in smelting or heat treatment facilities
- Energy performance diagnostics on existing lines: thermal audits, simulations, efficiency improvements
- Strong presence in regions with metallurgical activity (Savoie, Isère, etc.), with field expertise in aluminum facilities, steel mills, and flue gas treatment
Embedded
We support contractors and subcontractors in theaerospace, spatial, defense, and civil embedded systemsautomotive, rail, marine). These sectors have specific requirements :
- Weight, space, and safety constraints : thermal and aerodynamic/hydraulic optimization in highly compact designs
- Variable operating conditions : extreme climates, vibrations, thermal cycles
- Support for the design of new systems : compact heat exchangers, heat pipes, innovative fluidic systems
- Research into new fluids, materials, and thermal integration
Industrial refrigeration & HVAC
We support industrial refrigeration stakeholders (agri-food, storage, transport, air conditioning) in the design, analysis, and optimization of heat exchangers and associated thermal systems.
- Sizing of thermal equipment : heat exchangers, evaporators, condensers, recuperators
- Studies with specific conditions : retrofitting of refrigerants, transcritical operation, low temperatures, cryogenics
- Expertise in the event of malfunction : performance verification, model recalibration, fault identification
- Optimization of thermodynamic systems : refrigeration cycle, seasonal performance, energy savings, heat pumps
- Development and supply of the internal RefriHVAC™software, dedicated to cycle studies, AHU, cold rooms, etc.
Food industry (IAA)
The food industry has specific thermal constraints related to the nature of the products (complex rheology, mixtures, solids, sensitive fluids) and health requirements :
- Sizing of suitable equipment : heat exchangers, heated or cooled tanks with agitation, brine baths, thermo-vis, double jackets
- Studies on unconventional products : pastes, emulsions, suspensions, viscous products
- Optimization of thermal processes : performance improvement, consumption reduction, ramp-up
- Heat recovery solutions : hot drying air, process water, or various thermal discharges
- Integration of hygiene and regulatory constraints into the proposed solutions
Energy generation and conversion
We support projects related to conventional or renewable energy production (steam, cogeneration, nuclear, ORC, SMR, etc.) through services focused on heat exchange equipment :
- Multi-point simulation and sensitivity analysis: partial load operation, transients, cyclic operation
- Design of heat exchangers for new power plants : air technologies, Shell & Tube TEMA (E, F, K), specific condensers
- In-depth technical expertise : diagnostics, model recalibration, thermal aging analysis
Water, waste & energy transition
We support players in the environmental, water treatment, and decarbonization sectors in projects with significant energy and technological challenges :
- Heat recovery solutions for wastewater, effluents, digestates, wet flue gases: sources, sizing, recovery
- Studies for evaporation, concentration, and desalination : energy optimization, volume reduction, thermal integration
- Expertise in thermal fouling in loaded or biological environments (grey water, industrial water, digestates)
- Energy transition projects : H2 systems, ammonia, methanization, use of low GWP fluids, adaptation of exchangers to new vectors
- Environmental approach to thermal performance : an underperforming or fouled exchanger can account for up to 40% more emissions in a facility—our expertise aims to maximize real efficiency
We work on innovative projects as well as existing installations, with a focus on energy recovery, energy efficiency, and adaptation to new environmental standards.
