PROGRAMMABLE:
The heart of the new generation of
MRC disinfectors is the
leading-edge management system
controlled by microprocessors which
can control at all the activities performed & monitor,
using redundant systems, the entire flow of
information processed by the equipment. The entire
WG Series allows operators to programme all
washing parameters as they prefer, using the
multi-function membrane keypad or the PC directly
via the RS232 or LAN connections & the WD-TRACE
software ®. All significant parameters can be set.
These include: execution times, operating temp.,
quantity of additives, number of phases, and so on.
Access to the control operations is protected by a
system of four user passwords.
DRYING SYSTEM:
The forced-air “Drying System”,
completely modified in the new WG
Series, is a high-performance rapid
drying system. The system, comprising an efficient hot
air generator & a powerful fan, is directly managed
by the programmer which allows both operating
time and temperature parameters to be modified.
The microprocessor assures “intelligent”
management of the drying circuit by automatically
adjusting fan speed (thereby reducing power
consumption) according to the temperature
measured in the washing chamber. The air intake
passes through a class C filter with a 98% efficiency
rating.
PERISTALTIC PUMPS DETERGENT AND
NEUTRALIZER:
Disinfection effectiveness mainly
depends on the correct
performance of the washing phases and the
neutralization of the treated material. Models
WG-3060 and WG-4090 feature two peristaltic
pumps dedicated to dispensing the alkaline
detergent during the cleaning phase and the acid
neutralizer during the neutralization phase
respectively. Each pump is equipped with a level
sensor to be positioned directly in the can of the
products used.
About the models WG-2045, WG-1060 e WG-4060,
it is possible to install a specific optional pump to
dispensing the alkaline detergent.
ADDITIONAL PERISTALTIC PUMPS FOR
ADDITIVES:
The new WG models can have
up to two additional peristaltic
pumps dedicated to dispensing
additives (caustic soda, defoamers, inhibitors,
disinfectants). Each pump is equipped with a level
sensor to be positioned directly in the can of the
products used. system of four user passwords.
DETERGENT STORE:
Ergonomics, reduced dimensions and
practicality are indispensable
requirements for all equipment used in
busy professional surroundings. With these requirements in
mind, MRC has designed a detergent store located
inside the reduced dimension of the glassware washer
itself. It can contain up to four 2-Liter containers for the
WG-4090 Series and four 5-Liter containers for the
WG-6090 Series. No product feed pipes project from the
volume of the glassware washer.
LAN CONNECTION:
Thanks to the dedicated MRC WD-TRACE
software ® it is possible to visualise each
piece of equipment as though it were a terminal, thus
being able to store all the machine data directly on PC.
As information communication is two-way, it is possible
to directly dialogue with the disinfector microprocessors,
for example, in order to change the cycle parameters or
display a chart of internal temperatures.
PRINTER:
The traceability of the washing and thermal
disinfection cycles performed in
professional glassware washers is required
in order to check the operations have
been successfully completed. The printer is
an accessory which can provide a detailed report
containing all information relative to cycle performance.
In both the free-standing and panel versions, the thermal
printers used in the WG Series provide complete supporting
documentation for operators.
CONNECTION RS232:
A significant feature of the new-generation
equipment is that it incorporates the
devices required for the complete
communication of data relative to completed processes.
The range of last-generation WG features two standard
RS232 outputs, one for connection with the printer and the
other for connection with the PC in order to download all
the information relative to completed washing and
disinfection programmes.
THE PARAMETER Ao:
Is a numerical value deriving from an
equation that directly relates two
fundamental parameters: temperature and
thermal disinfection time.
Basically, the value of Ao defines the level of lethality of
the process expressed in seconds. The value appears
directly on the display and, if a printer is installed, it is also
included in the end-of-cycle report.
STEAM CONDENSER:
The steam condenser rapidly reduces the
saturated steam from the washing water,
especially during the thermal disinfection
phases. This device eliminates the formation of
condensation near the glassware washer and prevents
humidity and smells from escaping into the air, especially in
the versions positioned underneath worktops.
In air-conditioned rooms moreover, limiting the dispersion
of heat from the glassware washer reduces the work
load of the air-conditioning system, considerably
decreasing electricity consumption and unwanted
temperature changes.
