2.1.1 Frame
The modular structure of this equipment is made up of pressed-formed sections in galvanized sheet elements painted with a RAL 9004
epoxy powder cycle.
The elements are assembled together to make up a sturdy frame, capable of supporting units parts and to sustain strain which may derive
from unit handling and operation.
The devices are arranged inside the frame in a way that they are easy to reach from the front to make necessary handling during unit
operation and easier, more safety maintenance.
