4 Notes on planning
Prior to designing and selecting a Condair FF2 humidification system the following preparatory steps
must be carried out:
• Collecting site-specific data required for system design (see chapter 4.1)
• Selecting the desired options (see chapter 4.2)
4.1 Record of site-specific data
Your Condair representative needs the following data for proper system design:
Duct dimensions
Width (inner) mm _________
Height (inner) mm _________
Length (inner, min. 1300 mm) mm _________
Wall thickness of duct in the area of the water tubing pass-through mm _________
Air velocity in duct, or m/s _________
air volume to be humidified per hour m3/h _________
Air pressure (absolute) in housing --> not mandatory necessarily Pa _________
State of supply air prior to humidification
Temperature T1 °C _________
Humidity x1 g/kg / %rh _________
Desired state of air after humidification
Temperature T2 °C _________
Humidity x2 g/kg / %rh _________
Important notes:
– If a particular site is to be equipped with several FF2 systems determine the above data for each
system separately. Your Condair representative will then evaluate whether the particular systems
may be operated in a master-slave compound configuration.
– Evaporating aerosols cools down the air inside the duct (adiabatic cooling effect). To achieve the
desired air temperature the supply air must be heated prior to humidification.
