• e MicroMax370 is part of a range of control units adapted, with the necessary
additional functions, for optimum control of rotary heat exchangers.
e series consists of four sizes, MicroMax, MicroMax180, MicroMax370
and MicroMax750. All of the control units drive three-phase induction motors
with associated gearing, the control unit designation denotes motor output.
All control units have an input signal of 0-10 V.
• MicroMax370 is designed for wheels up to 3500 mm with a wheel speed of
max 12 rpm.
If a faster wheel speed is necessary, rotor diameter should be reduced.
• Heat exchanger rpm and thus thermal eciency are governed by the control unit
so that wheel speed is proportional to the input signal from the control centre.
• MicroMax370 has a customisable threshold of 0-2 V.
• MicroMax370 has adjustable boost function.
• MicroMax370 has a rotation monitor (magnet mounted on the wheel with
associated magnetic sensor) and built-in cleaning function.
e functions can be disconnected via DIP switches.
• MicroMax370 starts automatically following voltage
drop-out and resets all alarms on restart.
• e motor should not be disconnected from the control unit while under load.
