3.4 Pre- and post-treatment
Pre- and post-treatment of the process air can be performed by the following functional components:
■
Inlet dampers to enable isolation of the unit from the air flow. The dampers are installed on the outside
of the unit.
■
Heating coil: The coil can be electric or use hot water or steam as heating medium. The coil must then
be connected to an external heating medium supply. It is possible to activate a pump from the control
system.
■
Cooling coil: The coil uses chilled water, possibly mixed with glycol. The coil must be connected to an
external medium supply. The control system regulates an actuator to maintain dew point and or cooling
setpoint. It is possible to activate a pump and/or a chiller from the control system.
■
Filters for various air quality specifications. Filters can be equipped with pressure drop sensors to enable
"blocked filter" alarm (option).
