Energy refurbishment
The Frankfurt Airport Terminal 2 has upgraded the air handling centres in its Buildings 151 (West) and 150 (East) in close cooperation with NOVENCO Building & Industry.
Each centre consists of three identical chambers with a volume flow of 300,000 m3/h per chamber. Together, the system handles an outdoor volume flow of 1,800,000 m3/h.
The air is filtered and heated before large fans distribute it to the downstream air handling units.
Optimisation features
The concept
Modern ventilation systems often lose valuable dynamic fan pressure, wasting kinetic energy and increasing operating costs. With today’s fan technology, the total pressure — and thus the total airflow energy — is effectively utilised. System efficiencies of up to 85% are achievable.
NOVENCO Building & Industry supports customers in meeting climate targets with cost-efficient, future-ready solutions.
Summary
The use of ZerAx fans, advanced components and optimised system design shows how much ecological impact can be reduced in large ventilation systems.
At Frankfurt Airport, energy consumption, raw material usage and CO2 emissions are all significantly lower than with the previous solution.
With 92% fan efficiency, a 98% recyclability rate and a lifetime of more than 20 years, NOVENCO ZerAx axial fans offer a long-term, sustainable and efficient path to a greener future.
