Series RIF
An innovative,
standard-setting ventilation system.
The design of these ventilators has been considerably improved in
a joint project involving GAL engineers and the German Aerospace
Centre (DLR) scientists in Göttingen. The aim of this project
was to map flow patterns (in order to optimise the flow path and
avoid flow separation). This aerodynamic research project led to
the development of the Series RIF.
The world's highest coefficient of discharge Cv0 = 0,78
makes the Series RIF ventilator ideal for buildings with extreme
heat loads resulting from technological processes. The Series RIF
high-capacity gravity roof ventilator is distinguished by the following
features:
- The Series RIF gravity roof ventilator delivers twice the capacity
of conventional ventilators, yet it has the same constructional
dimensions.
- The structural weight of the Series
RIF gravity roof ventilator has been reduced by approximately
30% through improved design loads that have been verified in wind
tunnel tests.
