[to know more][hide details]

The rolling bearing washing machine allows the washing of radial rolling bearings with or without internal track.
It consists of an input conveyor where the bearings are loaded. Then they are conveyed automatically into the washing and drying cabin which has a washing and a drying spray pole in its inside.
At the end of the washing cycle the bearings are ejected on the output conveyor, and conveyed to the manual inspection bench.
Then a dewatering manual platform dips the bearings into a dewatering oil bath to eliminate the water left and to guarantee a protective oil coating of the bearings now ready for storage.
The machine is positioned at floor level so no civil work is required for its installation.
The washing is a closed-cycle one with hot water at high pressure (36 bar): there is no need of detergents to obtain a very good result.
To heat the water different energy sources can be used. The tendency is to use the energy source available in the workshop.

Process Tanks

Industrial washing machines for the cleaning of pieces with irregular surface.

[to know more][hide details]

The process tanks are machines used to wash metal pieces with irregular surface.
The pieces to be washed are introduced into the washing tank and are processed thanks to the double action of the washing solutions and of the movement of the water generated by the machine.
The machine can be used for chemical treatment and to degrease, pickle or decarbonate the pieces.
The water movement can be produced by the rotation of propellers positioned on the internal sides of the tank –turbolator system-, by the movement of the water made by external pumps –flow system-, by the cavitation action produced by the pressure of nozzles –hydrocav system-, or by the handling of the pieces in the tank.
The tank size can vary according to the pieces to be washed and to the room available for its installation.
The process tank can be heated with an electrical or gas system and an aspiration and depuration system can be added.
The machine can also be equipped with a mobile platform to introduce the pieces, with a control and management PLC based system and with a filtering system to guarantee lower water consumption and minimize the environmental footprint.

The conveyor belt washing machine is the best solution for the washing of loose parts from train, tram and metro maintenance cycle in the workshops where an automated processing line is installed.
The machine is completely made of stainless steel to avoid chemical corrosion and to increase its operating life. It consists of two booths –one for the washing and one for the rinsing- where fixed spray poles are installed.
The pieces to be washed are loaded on a belt conveyor which drives them through the booths at an adjustable speed according to the dirt on the pieces to be washed.
If specific treatment is requested (the application of an anti-rust, for example) specific booths can be added on the belt conveyor path.
The conveyor and the booths are positioned on the tanks to ease the closed-cycle recovery of the water.
Electrical heaters are provided to heat the washing solution. As an option, also the rinsing solution can be heated.
The machine is installed at floor level so no civil work is required for its installation.

Rotating Platform Washing Machines

For the cleaning of motors and big size parts.

[to know more][hide details]

The rotating platform washing machine has been designed to wash electrical motors, diesel engines heads and big dimension pieces.
The platform, initially outside the machine, is automatically introduced into the cabin after being loaded.
The washing is affected by the combination of the rotating platform and of the water sprayed by rotating and movable spray nozzles.
The closed loop washing and rinsing is obtained using cold and hot water heated by an electric or gas system.
An aspiration and depuration system of the fumes generated during the washing cycle can be fit in the machine.
To reduce water consumption and environmental impact, it is possible to filter the washing solution by a filtering system and the washing tank can be top-up using water from the rinsing tank.
To guarantee a constant supervision of consumption parameters, a control and management PLC based system can be added.

Vacuum Dryer Machines
