MicroMax180 is intended for rotors up to 2 500 mm with a rotor speed of max 12 RPM. If the wheel requires a faster wheel speed (12-25 rpm), the rotor diameter should be reduced.
Standard delivery includes an enclosed control unit, but can be supplied in a customised format. All control units in
the MicroMax series can be included as components in one of our popular Drive sets.

Function description
The MicroMax product series consists of modern control units with specific additional functions for the optimal control of a rotaing heat exchanger.
Input signal 0-10 V
Heat exchanger RPM and consequently thermal efficiency are steplessly governed by the control unit so that rotor speed is proportional to the input signal from the control centre. If the input signal is less than the set threshold value the rotor is stopped.
Cleaning function
When the rotor has been still for 30 minutes, the cleaning function is activated and the rotor rotates for 10 seconds at 12 RPM.
Rotation monitor
The rotation monitor stops the control unit and generates an alarm if the rotor stops rotating. The control unit generates an alarm and trips unless a pulse is received every 5 minutes. The alarm event is retained.
Alarm
The control unit trips and generates an alarm in the event of over or under-voltage, short-circuiting or earth leakage, and if a thermal switch has tripped inside the motor. All alarm events are retained.
Test
DIP switch for manual run at high or low speed RPM.
