4.1 Drive
The wheels are driven by a worm gear or a spur-gear drive
motor using a v-belt; the type and size of the motor depends
on the wheel diameter:
■ Drive Y
for direct drive by mains power. On/Off operation at
constant speed only.
■ Drive A
The motor speed and therefore the performance of the
rotary heat exchanger can be controlled. A control unit
(option R) is required.
