Aging fans drain energy and reliability
Project Meander II Amsterdam garage faced operational issues with their aging ventilation system. The outdated single-phase, dual-speed transformer-controlled radial fans created problems: high energy consumption, declining reliability, and increased maintenance requirements. Facility managers needed a solution that would reduce operating costs while improving system reliability without disrupting daily operations.

The solution replaced problematic fans with two NOVENCO® ZerAx® axial fans specifically designed for car park applications. These advanced fans addressed all the operational challenges while providing substantial performance improvements from day one.
The retrofit delivered measurable performance improvements across multiple areas:
- Energy reduction - Total power consumption dropped from 3.2 kW to 1.6 kW
- Immediate savings - 50% energy reduction compared to the previous system
- Smart operation - Variable speed control enables 80% or greater savings during low-demand periods
- Space efficiency - Compact design improves facility layout and reduces installation complexity
Technical solution details
Frequency converter technology enables automatic adjustment based on real-time conditions. The system integrates with existing gas detection systems, ensuring ventilation responds precisely to air quality needs. Variable speed control reduces fan speeds during low-traffic periods, so the system only consumes energy when necessary. This intelligent operation prevents the waste associated with constant full-speed operation while maintaining air quality standards.
The frequency converter approach provides operational flexibility that transformer-controlled systems cannot match. Because the system adjusts continuously rather than switching between two fixed speeds, it maintains optimal airflow at all times. This smooth modulation reduces mechanical stress on components and extends equipment life.
This retrofit demonstrates measurable improvements beyond the 50% baseline energy savings. Enhanced system reliability reduces maintenance calls while improved airflow ensures consistent air quality throughout the facility. The compact ZerAx® design freed valuable space previously occupied by larger radial fans, allowing facility managers to optimise the garage layout. Operational noise levels decreased significantly, improving the environment for both users and nearby residents.
