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.
