Minimum and maximum flows from ProSelect limited by the available pressure and nozzle configuration selected for an
ADAPT Parasol 1200 HF LMLM.
Min. occupancy flow is selectable in ProSelect and here is set to 15 l/s.

In SWICCT or by configuring ADAPT Parasol in ProWISE limits can also be set for unoccupied and occupancy max flow
(note the product's absolute min and max from the previous figure which are controlled by the selected nozzle setting!)
By letting the most exposed product in this way be the design unit for the current duct section and taking this into
account at an early stage, you do not use a balancing damper before each product and can thus save both available
pressure and money on unnecessary balancing dampers, which in addition also risk creating noise.
Of course, the pressure fluctuations in a duct system can be so large that a traditional balancing damper may still be
required, but in all probability a damper in front of each product is not necessary as it should be enough to lower the
pressure in some of the duct system and then apply the above.
