The inner drum is driven via four V-belts by a frequency-controlled motor,
which is mounted on a motor mounting plate under the drum assembly.
The motor mounting plate is adjustable, so that belt tension can be regula-
ted. The motor has a microprocessor-controlled control unit which allows
the motor speed, acceleration and deceleration to be controlled with high
precision.
The drain valve is a diaphragm valve which is operated by compressed air.
The door is locked when the program starts.
The machine is supplied complete with a microprocessor-based control
unit.
The electrical components are in the automatic control unit on the machine
rear.
The machine exterior is made up of:
• Front panels of stainless steel.
• Back cover of hot-dip galvanised steel, painted white.
• Side panels and top cover of either stainless steel or of hot-dip galvani-
sed steel.
