PREO P20

The new P20 EASY TOUCH applicators for hot-melt adhesives with pneumatic pump are significantly innovative in terms of simplicity of use, productive flexibility, maintenance operations and costs, speed of installation, easy programming, high safety standards, exceptional reliability and total integration with any existing assembly line. They represent a quality solution for application of thermoplastic hot-melt adhesives in several sectors. The EASY TOUCH systems are equipped with a new microprocessor with 7" LCD Touch Screen colour display, through which, with a single graphic interface showing all sections of the system (tank, manifold, hoses and pistols).The operator is supported in everyday activities like managing and setting the temperatures, pump control, setting machine parameters and glue sections, and integration and communication with any external units, allowing for immediate use of the system even by non-specialized personnel, without any problems involving codes or foreign languages to be interpreted. The EASY TOUCH melters have a new melting tank, entirely redesigned, to distribute the heat more evenly over the entire surface, thus obtaining a more precise and effective melt, with significant energy savings. The particularly well-finished design makes the system appreciable even in aesthetic terms. Every part of the applicator can be inspected easily by opening the practical body system. EASY TOUCH Applicators - customizable in several configurations and capable of satisfying all gluing needs - allow the operator to work in complete safety and to significantly optimize application times without wasting time uselessly.

NEW MICROPROCESSOR WITH 7" TOUCH SCREEN DISPLAY
The following are some of the main functions of the new user interface: sequential channel heating, machine ready and pump start signals, absolute maximum temperature protection system, Economy Dual Mode, Weekly Program with Daily ECO function, colour status button with real time diagnostics and Screen Saver function, hose-pistol coupling thermal regulation deactivation, LOG file for system register, Life Hours/Work Hours/Pump Cycles counter, machine parameters and Firmware updates uploaded and downloaded through a USB port, customizable system section and glue program names, and parameter Copy/Paste function

NEW MELTING TANK WITH 20 LT CAPACITY
The new tank was entirely redesigned to ensure perfect efficiency in terms of melting evenness and capacity. The large loading inlet open on 3 sides makes willing easier, optimizing cleaning and maintenance operations. The resistance shaped and positioned on the bottom of the tank distributes the heat in an even manner, improving thermal efficiency throughout the system, thus resulting in energy savings. The tank bottom slope (about 20°), the fanned melting fins - positioned parallel to the upper edge of the tank - were designed specifically to improve melting the glue, so it can slide directly towards the pump drawing spot. The rapid discharge - located at a lower level and on the opposite side compared to the drawing spot - facilitates the collection of any impurities in the adhesive or burnt glue residue, conveying them to a single sump and preventing them from being sucked up by the pump and causing a machine shut-down, also allowing for quick cleaning operations either for maintenance purposes or to replace the adhesive.

ELECTROMAGNETIC INVERSION SYSTEM
Guarantees absolute precision in the pneumatic pump inversion cycle, thus assuring that the adhesive flow rate is always constant and balanced, significantly reducing the lack of adhesive during the inversion cycle. The use of reed-switch type proximity sensors (protected and sealed inside the electronic cylinder, and therefore never in contact with the outside environment and not subject to wear) increases the reliability of life cycles, reducing machine shut-downs for malfunctions or maintenance, giving the system mechanical solidity, in addition to resistance to environmental conditions and to electrical and electromagnetic disturbances.

PRE-INSTALLED PNEUMATIC CONNECTIONS
These allow a quick and safe system commissioning.

ACCESSIBILITY
All the internal parts of the applicator are easy to inspect thanks to a body system easy to open.

HIGH PRECISION PNEUMATIC PUMP
The 14:1 dual-effect piston pump is ideal for melting and applying adhesives and thermoplastic materials with a viscosity of up to 30,000 Cps. Treated with a hard oxide coating, it is easy to extract in case of maintenance or replacement operations. The bottom of the pump is inspectable in order to check the conditions of the suction sphere.

GLUE FILTER
Easy to access and replace, it guarantees excellent quality of application, preventing impurities in the adhesive from clogging the nozzles. There is a wide range of available models (with single or multi-layer filtering micro-mesh, and different pitches starting from 200 micron) depending on the type of adhesive used.

AUTOMATIC PRESSURE RELEASE VALVE
A standard part, it guarantees maximum safety during operation by automatically discharging residual pressure in case of emergency or system shut-down.
