Line 03 · Industrial Ventilation & CFD
We measure it point by point, scan the space as it stands today, and simulate the flow. You see the dead zones, the pressure field, and the real path the air takes before you approve an investment, not after it is installed.
Before you invest
The geometry comes from the plant as it stands today, not from the original drawings.
The problem
The fan turns, the air handler draws power, and the bill arrives on time. And yet there is a zone where the air never changes, a reversed pressure that carries odor from one area to another, and an airflow nobody has measured since installation. None of it is visible from the floor — and it explains why the problem came back after the last investment.
What we do
Four fronts you can contract separately, though the value is almost always in chaining them together.
Field airflow measurement with a Pitot tube and a micromanometer for low velocities, a mass balance of inlets and outlets, and point-by-point adjustment. Almost always, the system turns out to move less air than the design promised.
Computational modeling of the airflow across the whole space. It gives you flow patterns, dead zones, the pressure field, and air residence time, and it lets you compare scenarios before executing any of them.
Relocating diffusers and exhaust points, local exhaust ventilation at the source, reducing infiltration, and sizing the capacity you really need — which is often less than what is installed.
An LOD 400 point cloud of the room as it stands today, and on top of it the CAD model with piping, skids, equipment, ductwork, conveyors, and racks. It feeds the simulation, and it also stays on as living documentation of the plant.
How we simulate
We scan the real space, rebuild it in three dimensions, and simulate the flow. What you cannot see on the floor, you can measure in the model.
Flow patterns, dead zones where the air never changes, the pressure field between areas, and air residence time. Four things you cannot see on the floor, and they explain why a room feels wrong even with the system running.
From an LOD 400 point cloud scan of the space as it stands today, not from the original drawings. On that real geometry we build the CAD model with piping, skids, equipment, ductwork, and racks, and from there the computational mesh.
To relocate diffusers and exhaust points, reduce infiltration, meet aerosol control and hygiene policies, and size the real capacity you need before you buy it.

A case
A packaging room with four air handling units, more than fifty air conditioning supply points, and a corporate aerosol control and hygiene policy to meet. And, in parallel, an energy savings target that required cutting the airflow without compromising the operation.
Field data collection and airflow measurement with a Pitot tube and a micromanometer for low velocities. Measurement, adjustment, and air balancing of more than two hundred exhaust points. A mass balance of the room's inlets and outlets. And a CFD model to evaluate flow patterns, dead zones, the pressure field, and air residence time.
The client was able to bring the room up to a safe operation for its people and plan the next lines from the capacity already installed, instead of buying new capacity.

Other studies
All of them start from a scan of the real space and end in a decision backed by a number.
A detailed CAD model with piping, skids, the operator area, motor control centers, and pumps. We simulated scenarios to propose new diffusers and exhaust locations, and studied how to reduce infiltration.

Tell us which room worries you and why. The first conversation costs nothing and ends with something concrete: a read on the problem and a possible path forward. If air balancing is enough and there is no need to simulate, we will tell you that too.
