3 Product overview
3.1 Model overview
The Condair MD consists of a hydraulic unit and a humidier unit for installation in horizontal ventila-
tion ducts and has a maximum humidication output of 2 kg/h. The humidication water is heated via
the integrated heat exchanger, which is connected to the heating water system (35 ° C… 60 ° C) of a
connected to a oor/wall-based heating system with a circulation pump or a convection circuit with a
circulation pump.
Note: The stated humidication output is the maximum value, measured at an air throughput rate of
180 m3/h. The effective humidication output depends on the heating source output, the condition of the
supply air and the adjusted humidity setpoint. The output has been veried by Fraunhofer Institute for
Solar Energy Systems (ISE), Freiburg, Germany.
The functionality of the Condair MD can be enhanced using various options. Different accessories and
consumables are also available.
