operating principle is based on a basket holder with revolving
movement and a certain number of nozzles with high flow and impact.
The system is driven by a gearmotor with torque limiter and can
hold a basket for parts in batch or a pallet. Revolving movement
can be continuous or indexed for precision cleaning of difficult-to-reach
zones, holes or recesses.
machine consists of a chamber with the spray and the revolving
systems accessible through a front door, and one or two tanks
posed and the process chamber.
ROTO-SPRAY® washers can be configured for a single stage - only wash - or
multi stages process for wash, rinse and eventually drying. The
operating cycle is fully automatic controlled by PLC.
automatic cycle is started by the operator: the basket holder
initiates the rotation and the following functions:
- Wash the wash pump starts and stops
at the end of the time
- Stand-by wash liquid flows back to its tank
- Rinse the rinse pump starts and stop at the end of the time set
- Stand-by rinse liquid flows back to its tank
- Ventilation centrifugal fan starts - cool air from the ambient enters the
chamber - the chamber is purged
of vapours - the fan stops
- Drying blower and the air heating start creating a hot air stream within
the chamber - the heating
the end of the time set - then
the fan stops - the basket holder stops
- the door opens
liquid reservoir is easily accessible for maintenance. It is equipped
with facilities for manual and automatic fill, discharge of spent
liquid, marine type clean out door for internal cleaning, low/high
level control and overweir. Before reentering the spray circuit
the wash liquid passes through a basket filter.
electric box contains all the electric equipment, relays and instrumentation.
The control panel is composed by instruments and lamps or the
PLC program panel with LC Display for time and temperature settings,
heating up timer, fault survey.
ROTO-SPRAY® washers are produced for standard baskets of mm. 500 x 320 x 200,
or larger in special execution, and can be integrated with additional
facilities and systems for automatic filling with transfer of
the liquid, mist eliminator RETEN-MIST® or vapour condenser VAPOR-MIST®,
oil separator OILNET®,
bag or cartridge type filtration, vacuum condensers DI&DRY® to separate contaminants generating DI water in a closed circuit.
