Custom Ventilation Engineering
Airflow engineering is at the heart of every MECAVENT project.
MECAVENT applies its ventilation engineering expertise to installations that do not fit into any catalog: limited space, existing networks to be adapted, or flow, pressure, and noise constraints. On-site surveys, 3D modeling, flow simulation, and custom manufacturing: we design the part or equipment that solves your problem.
Example: duct at fan outlet
Problem identified on the installation:
- poorly designed duct at fan outlet;
- significant pressure drop;
- disturbed airflow.
Solution: a new duct designed in 3D and validated by flow simulation (below), then custom-manufactured.
Airflow engineering: from calculation to commissioning
Good airflow engineering avoids oversized fans, noisy ducts and unbalanced networks. At MECAVENT, each project starts with a study of your process: required airflow at each point, pressure losses, gas temperature and composition, dust load and noise constraints. From these data we design the complete network, select the fan and size the silencers.
We use computational fluid dynamics (CFD) to visualise flows in bends, plenums, hoods and fan inlets. CFD simulation reveals recirculation zones, uneven velocity profiles and areas of high pressure loss before anything is built, so that the design can be corrected on screen rather than on site.
Acoustic calculations
Airflow engineering and acoustics go together. We calculate the sound power of fans and the attenuation of silencers, enclosures and louvres to predict noise levels at the workstation or at the nearest neighbour, and to choose the most economical acoustic treatment.
Custom designs for complex cases
Our airflow engineering team designs special fans, transition pieces, plenums and complete air handling systems for retrofits, limited spaces and demanding processes, then follows the project through manufacturing, installation and commissioning.
Why airflow engineering pays off
A well-engineered ventilation system uses less energy, runs more quietly and needs less maintenance over its lifetime. Investing in airflow engineering at the design stage avoids costly modifications after start-up, such as replacing an undersized fan, rebalancing a network or adding silencers that were not planned. Our engineers remain your single point of contact throughout the project, from the first site measurement to the final acceptance test, so that the installation delivers the airflow, pressure and noise levels agreed at the start.
New Duct with Flow Simulation
Custom Filtration Units for Chimneys
For an existing installation, MECAVENT designed 8 custom air filtration units, mounted directly on a chimney. Their curved shape perfectly matches the wall’s contour.
The process: taking measurements from existing plans, 3D modeling of each element (grille, filter media, seal), then manufacturing and painting the parts before on-site assembly.
Before
Replacement of Existing Fan and Installation of an Extraction Duct
Problem: an extraction fan at the end of its service life and an unsuitable duct network on an industrial installation in operation.
MECAVENT Solution: on-site survey, sizing of a new fan and a suitable extraction duct, manufacturing, then on-site installation. A turnkey intervention, from study to commissioning.
After:
Custom Fan
On-site survey, design, and manufacturing of a fan intended to replace existing fans.
An ideal solution when the original model is no longer manufactured: MECAVENT takes the connection dimensions and adapts the aeraulic performance to the current needs of the installation.
