5 KG HOT-MELT APPLICATORS WITH GEAR PUMP
EASY SERIES W5
The new W5 Easy Series applicators for hot-melt adhesives are the top innovation on the international market for their simplicity of use,
production flexibility, maintenance costs, quick installation, ease of safety standards, exceptional reliability and full integration with any
packaging line, granting the maximum operational flexibility. The new microprocessor controls all those operations necessary to the system
proper running: thermo-regulation in all different system areas, programming control of 8 glue tracks for each of the 4 independent
channels. Additional features are: Economy Function, Clock, Weekly Program, Max. temperature alarm, Sequential Heating of all channels
and delay Temperature Set Point lock.
NEW MELTING TANK
A large loading inlet, opened on three sides, makes the 5 kg
tank filling easier.
REMOVABLE COVER
Unique in its category, the cover is quickly removable in order
to grant the maximum cleanliness and proper maintenance.
LCD DISPLAY
A new LCD display (specifically designed) graphically shows all
the machine sections (tank, manifold, hoses and guns with
respective parameters), allowing an immediate and extremely
easy system programming also by unskilled operators,
eliminating problems generated by codes and foreign
languages to understand and meaning that the displays are all
the same, independently of the country of use. A specific
notification area controls the system status constantly and
dynamically in all its operation phases. In case of eventual
alarms or faults error messages are displayed.
INNOVATIVE PROGRAMMING
Another innovative feature of the new Easy Series is the “Rotary Switch”: the
selector through which it is possible, with extreme easiness, to program, modify
and set section by section all those parameters intended for the system running.
GEAR MOTOR
The applicators are fitted with variable speed AC motors
controlled by inverter positioned horizontally so as to have
reduced overall dimensions and ease to access both for
inspection and maintenance, thanks to a quick connector and
to an easy to open body system.
ACCESSIBILITY
All the internal parts of the applicator are easy to inspect thanks to a body system
easy to open.
GLUE FILTER
Easy to access and replace, it ensures a better distribution of
the adhesive preventing the nozzle clogging due to the
presence of impurities in the adhesive.
PRESSURE CONTROL DEVICE
A sophisticated control system shows on the applicator display
the adhesive output pressure in the manifold. This visualisation
is comparable to a traditional digital pressure gauge indicating
the adhesive pressure in bar.
HIGH PRECISION GEAR PUMP
With the same dimensions it is possible to choose between
gear pumps of different capacity. Absolute precision and
reliability, they are made of super-quick steel and are fully
hardened. Like all the inside parts of the applicator, also the
pump is easy to remove in case of maintenance or
replacement.
QUICK PRESSURE RELEASE AND REGULATION VALVE
It keeps the pressure set constant and ensures the utmost
safety during the system use by and releasing the adhesive
pressure into the system in an automatic and safe manner,
even in the event of an emergency.
