Installation of General Ventilation Systems in Brussels
Mevrouw Laurence Lemaire, die een mede-eigendom van verschillende woongebouwen beheert, nam contact met ons op om de luchtkwaliteit en de veiligheid van de bewoners te verbeteren. Verschillende appartementen hadden te kampen met een slechte luchtverversing, met name in de keuken, badkamer en toiletkanalen, wat leidde tot vochtigheid en aanhoudende geurtjes.
The objective was to install an efficient and quiet centralised ventilation system capable of continuously renewing the air in all dwellings in accordance with current standards.
Following a technical study of the building and its existing ducts, we proposed and installed a controlled mechanical ventilation (CMV) system in the roof, comprising:
High-performance extraction boxes
Insulated galvanised steel ducts for extracting stale air
Roof caps for high-level drainage, limiting noise and odour return
The work took place over two days, with secure access to the roof.
The condominium now benefits from constant, silent air renewal, reducing humidity in the homes and improving overall comfort. Mrs Lemaire thanked us for our rapid, discreet intervention, which complied with safety standards.

Installation of General Ventilation Systems in Brussels | Frigotec
Experts in Industrial and Commercial Ventilation in the Brussels-Capital Region
The air quality in your business premises has a direct impact on the health of your employees and the performance of your company. Frigotec, a recognised specialist in Brussels, supports you in the design and installation of high-performance general ventilation systems that comply with Belgian standards.
What is a General Ventilation System?
General ventilation refers to all equipment and processes used to renew indoor air by removing polluted air and replacing it with purified outdoor air. Unlike localised extraction, which targets specific emission points, general ventilation ensures complete air circulation in your workspaces.
Why Choose Controlled Mechanical Ventilation?
In the Belgian climate, with its harsh winters and changeable weather conditions, natural ventilation is not sufficient to guarantee optimal air quality throughout the year. Mechanical systems offer:
- Precise control of air flow rates
- Effective filtration of external particles
- Preheating the air during cold periods
- Automatic regulation according to requirements
- Guaranteed regulatory compliance
Key Steps for a Successful Move to Brussels
1. Needs Analysis Based on Your Business Activity
Each sector of activity has specific requirements in terms of air renewal. Our Frigotec engineers carry out a comprehensive audit of your facilities to determine:
- The volume of air to be treated (in m³/h)
- The hourly renewal rate tailored to your industry
- Critical areas requiring special attention
- The architectural constraints of your Brussels building
Examples of recommended rates:
| Type of EstablishmentRenewals/Hour | |
|---|---|
| Metalworking workshops 4 to 6 times | |
| Logistics warehouses 1 to 2 times | |
| Textile industries 2 to 3 times | |
| Printing workshops 2 to 4 times | |
| Electronic production spaces 3 to 5 times |
2. Precise Technical Dimensioning
Our design office accurately calculates the required performance:
Calculation of the required extraction flow rate:
- Area of your premises × Ceiling height × Hourly rate
- Adjustment according to polluting activities
- Consideration of existing extraction systems
Calculation of fresh air supply:
- Volume corresponding to 90-95% of the extracted air
- Maintaining slight negative pressure to prevent the migration of pollutants
- Sizing of air handling units
3. Distribution Circuit Design
The efficiency of your ventilation depends as much on the size as on the strategic location of the equipment:
Optimal Investment Principles
Extraction of stale air:
- Positioning in areas with high concentrations of pollutants
- High-level installation to capture contaminated hot air
- Balanced distribution to avoid dead zones
Fresh air intake:
- Placement in the cleanest areas of the establishment
- Controlled diffusion to create effective sweeping
- Flow direction from the clean area to the contaminated area
Efficient Traffic Flow Diagram
The objective: to create a directional airflow that moves throughout your premises, gradually pushing contaminants towards extraction points without creating excessive turbulence.
❌ Avoid: Side-by-side intake and extraction (short circuit)
✅ Recommended: Through-flow with opposite inlets and outlets
4. Selection of High-Performance Equipment
Frigotec selects industrial-grade components suited to your application:
Extraction fans:
- Moteurs haute efficacité énergétique (IE3 minimum)
- Flow rates adapted to precise calculations
- Low noise level for comfort
Air supply units:
- Multi-layer filtration (G4 to F7 as required)
- High-performance preheating batteries
- Automatic temperature control
- Optional heat recovery
Duct network:
- Optimised sizing to minimise pressure losses
- Thermal and acoustic insulation
- Materials resistant to industrial environments
