Casing
The casing consists of a robust, stainless steel structure. The machine stands on four height-adjustable
feet (6). It is fitted at the front with an upward opening service door (15). The belt cartridge (11) with the
internal conveyor belt is located behind the service door. The product infeed and outfeed openings are
equipped with a strip curtain (17).
The electric cabinet (26) is accessible from the rear of the machine. The access cover (22), to the left of
the electric cabinet, can be removed for maintenance tasks.
The name plate (1) is attached to the rear of the machine.
Water tank and heater
The water tank is accessible from the left-hand side. The spray water is warmed up in the water tank (9)
and enters the machine via a pump and spray nozzles. As regards the heating technology, two machine
versions are available:
•
With electric heater (VC999 ST2)
•
With steam heater (VC999 ST2 D)
Electric heater:
Four electric heating elements are integrated in the water tank for warming up the spray water.
Steam heater:
The machine is connected to a central steam generation unit. The spray water is warmed up using hot
steam that enters the water tank via a steam distributor.
The water level in the water tank is monitored by three electronic sensors in both versions. The water
can only be warmed up when the heating element (VC999 ST2) or the steam distributor (VC999 ST2 D)
are completely submerged in water, thus guaranteeing dry run security.
If the water level falls below the minimum permissible level, the water tank is filled with water via a
valve. This supply of water is switched off once the maximum water level has been reached.
Interfaces
Electrical connection:
The power cord can be routed into the electric cabinet (26) from the top or the bottom (28).
Water supply:
The connection point for the water supply (27) is located on top of the machine.
Water discharge:
The water discharge connection is equipped with an electrically operated ball valve.
Steam heater connection:
The machine (VC999 ST2 D) must be connected to a steam generation unit for steam heating. The
steam line is fed to the machine from the top.
Steam extraction connection:
The connection for the steam extraction (29) is located on top of the machine.
