HOT-MELT GUNS

SPRAY – SPYRO SERIES

SPRAY and SPYRO gun series are mainly employed for gluing wide surfaces where a low glue weight is required. Main features of SPRAYSPYRO guns are: AMX 45 module with double interchangeable gasket cartridge, Zero-Cavity self-cleaning nozzle with nebulisation air cap, air
heating block, possibility of a second solenoid valve for separate nebulisation air control, protective non-stick casing coating, integrated glue
filter which is removable without disassembling the hose. This wide, complete range of different models makes it possible for even most
demanding Customer to find the best solutions for any gluing needs. The wide range of models provides also the most demanding customer
with the ideal solutions for each gluing problem.

SOLENOID VALVES
In addition to standard solenoid valves, Preo has developed a new
model that is ranked at the top of the market offer. Depending on
the applications required, this valve can deliver the highest level
solution for tasks that require low energy consumption, high-speed
application and small size and weight.

ELECTRICAL CONNECTIONS
Removing the electrical kit is easy, simple and safe.

GUN CASING
The casing is built in "Ergal”, an aluminium alloy that considerably improves the
product’s resistance to mechanical stress. The hard oxide cover makes gun
cleaning and maintenance quick and easy.

THERMAL-HEATING
The gun is heated with highly reliable heating coils controlled by
extremely precise sensors.

HEATING BLOCK
Inside the gun casing is assembled a new heating block which keeps a constant
temperature of the air used for the product spraying, thus ensuring precise and
reliable results.

AMX 45 MODULE
All guns are equipped with a new AMX 45 Series module that
ensures precise, regulated glue application. This level of
performance was possible only because of the special attention
dedicated during the design and construction phases. The most
important aspect of the AMX 45 module is its innovative gasket
system with the double interchangeable cartridge, which
guarantees a perfect seal at high pressures and temperatures in
addition to simple, inexpensive, and long-lasting maintenance.

GLUE FILTER
This guarantees better distribution of the glue and prevents
nozzles from clogging due to the presence of impurities in the
glue. It’s integrated into the casing, and is easily accessible and
can be quickly replaced without disassembling the hose.

NOZZLE
The guns are available in 2 different series depending on the
provided nozzle: the Spray version is used for an even spraying
of the product, while the Spyro version allows you to obtain
spiral-shaped glue strips. The gun are supplied with stainless
steel Zero-Cavity self-cleaning nozzles, available with a
minimum diameter of 0.30 mm to a maximum of 1.2 mm. ZeroCavity is the term used for the cut-off that directly closes the
nozzle hole, eliminating any possible impurities and
guaranteeing the constant cleanliness of the nozzle. This
guarantees that the system always works properly. The wide
range of nozzles includes a number of configurations and
special designs, based on the Customer’s needs.
