In order to ensure a satisfactory function of the machine exhaust system, the subsequent pipe system that is
installed in the laundry, should as minimum be dimensioned according to the following guidelines. If the pressure
loss in the piping system is increased as a result of dimensioning faults, this will cause a reduction of the exhaust
and thus the machine capacity.
In case of short distances between the ironer and the outlet to the outside, i.e. less than 15m including allowance
for bends, the exhaust pipe can be made as a channel with diameter 125mm for all machine types.
In case of longer distances, we recommend to use a larger pipe diameter. When judging the exhaust channel,
see the following tables that deal with pressure loss and the dynamic pressure by different pipe dimensions and
also deal with the equivalent pipe lengths for different part elements in an exhaust channel.
Dynamic pressure (Pd) in [Pa] and specic pressure loss (∆p) in [Pa/m] dependent on volume ow in m³/h and
pipe diameter (dia) in mm. S is the speed in m/s.
