Scheveningse Duyn, a 48-apartment residential complex in The Hague, Netherlands, required complete car park ventilation replacement after 30 years of operation.
Project overview
Residential complex size requiring complete ventilation replacement
Original roof-mounted system age before replacement became necessary
Centrifugal car park jet fans installed for efficient air distribution
ZerAx AZL-400 axial fans with IE5 motors at 1.35 kW indicative power
Obsolete parts created critical maintenance problems
The original installation relied on two roof-mounted fans with extensive ductwork. Critical parts became unavailable, forcing maintenance contractors to source obsolete components at increased cost and extended downtime.
The system failed NEN 2443 compliance requirements for Dutch car park ventilation. Roof access complicated routine maintenance, exposing contractors to weather and awkward working positions during service visits.
These operational challenges demanded complete system replacement.
Equipment installed
- 2 CGF-500 centrifugal car park jet fans for air distribution
- 2 ZerAx® AZL-400 axial fans with IE5 motors (1.35 kW indicative power) for exhaust
- CO/LPG detection system compliant with NEN 2443
- NOVENCO control panel for automatic fan operation
- Electrical cabling and surface-mounted hostalith conduit
- Roof cowls and silencers
- Minimal ductwork for optimised airflow
Ground-level access
Simplified maintenanceStandard parts
No obsolete componentsNEN 2443 compliant
Full regulatory complianceModern ventilation delivers lasting benefits
The retrofit occurred whilst the car park remained operational. Installation teams coordinated with residents to minimise disruption. All electrical work, mounting, and commissioning completed within schedule.
NOVENCO handled complete commissioning, verifying airflow distribution, control operation, and sensor calibration. The detection system received functional testing to confirm NEN 2443 compliance.

Ground-level access cuts service time significantly
Ceiling-mounted jet fans provide ground-level access for routine maintenance. Contractors no longer require roof access or specialist equipment, reducing service time significantly.
All components use standard replacement parts with established supply chains. This eliminates the obsolete parts problem that plagued the original installation. Maintenance contractors source spares quickly, reducing downtime.
The centralised control panel simplifies troubleshooting and system adjustments. Clear status indicators help maintenance teams identify issues before performance degrades.
NEN 2443 compliance eliminates regulatory risk
The system meets current NEN 2443 requirements, eliminating compliance risk. CO/LPG detection provides continuous monitoring, automatically activating ventilation when needed.
IE5 motors and detection-based control reduce operating costs compared to continuous-run systems. With readily available parts and simplified access, the installation provides dependable service for decades.
Original system versus current installation
Original system challenges:
- Roof-mounted fans requiring difficult access
- Extensive ductwork throughout car park
- Critical parts unavailable after 30 years
- Non-compliant with current NEN 2443 standards
- High service costs due to access difficulties
Current installation benefits:
- Ceiling-mounted fans with ground-level access
- Minimal ductwork simplifies maintenance
- Standard components with reliable supply
- Full NEN 2443 compliance verified
- Reduced service time and costs
The new jet fan ventilation system has significantly improved the underground parking facilities. We benefit from improved air quality, reliable air quality monitoring and easier maintenance access. This modern solution not only enhances comfort and safety for residents but also ensures long-term efficiency and reliability for the building.
