3. Installation
3.1 Basic installation
Fig. 4 Emotron motor and Control unit for rotary heat
exchangers
The drive unit (motor plus reduction gear) is mounted on
the bracket located in the heat-exchanger, and the control
unit is mounted in a suitable position either in the heat-
exchanger housing or, e.g., a control room. Vibration damp-
ing material such as rubber anti-vibration mountings should
be inserted between the motor and the motor bracket.

3.2 Mounting the rotation
monitor
Fig. 6 Rotation monitor
The magnet for the rotation monitor is mounted tight on
the periphery of the heat-exchanger. If the housing around
the rotor is magnetic itself then the sensor magnet must be
isolated from the housing. The rotation sensor is mounted
to ensure that the magnet passes over it at a distance of 5-8
mm, see Fig. 6 .
