Association of M.A.R.V.E.L. system & Capture Jet™ technology ((64% reduction exhaust airflow rates)
Reduction would have been more important if the makeup air would have been air-conditioned… in fact M.A.R.V.E.L. automatically increase the exhaust airflow rates to benefit of a higher free cooling capacity.
The electricity consumption of a centrifugal fan is proportional to the cube of the rotation speed. Consequently, a fan that operates at 78% speed (average) has only 47% of the nominal power consumption.
Indoor temperature and humidity of the main kitchen:
The temperature variation is limited to 2,5°C as the humidity variation is limited to 6%… showing that the system operates well thus without compromise on the capture efficiency.
