The cooling tunnel consists of:
- base frame with integrated conveyor, drive and electronics,
- cooling tunnel,
- condenser (remote unit).
The advantage of the system lies in its adaptability to the shape of the pallet conveyor and the possibility of installing multiple cooling chambers (cooling at different temperatures). This allows straightforward integration of further equipment for automatic processing.

The press design allows integration into a production line where pallets with workpieces pass through the press. It is a four-column hydraulic press with a pressing and holding cylinder that allows uniform and controlled pressing.
The control system allows setting of operating modes (automatic, step-by-step and service) and monitoring of measured parameters:
- pressing force measurement,
- pressing cylinder stroke measurement,
- movement speed monitoring (time),
- data storage and forwarding to the system.

The glass transport line was designed for the production of acrylic sheets. The line enables automatic preparation of glass for assembling molds and pouring acrylic mass into the mold and dismantling the molds and sorting.
