Accessories
Level control system
The level of the hot-melt is done with an capacitive detector and the warning
is through a light tower.
Air drying system for PUR adhesives
Polyurethane-based reactive adhesives, known as P.U.R. (reactive
polyurethanes), require a completely dry environment before they can be
applied, since when they come in contact with atmospheric humidity, they
reticulate, hardening quickly.
The ‘B4 VARIABLE SPEED’ melting equipment ensures a dry environment
thanks to the addition of an air-drying system to these models, which provides
a level of dehumidification above 99.98%. This guarantees that the adhesive
is preserved without premature reticulations inside the applicator unit. The
installation of the electro-pneumatic control is a standard in all versions. You
can choose if you want to order the air-dryer assembly (two filters and the
dryer membrane) or not.
If not, you can use your own air-dryer system or another inert gas like
nitrogen (N
2
). Ask you adhesive supplier for more information.
Automatic tank filling system
Meler pellet loaders ensure a continuous level of adhesive inside the tanks of
the melting units, eliminating the need for manual loading by the user.
Each time the tank detector detects a low level of adhesive, it sends a signal to
the suction system, which transfers a load of pellets to the melting tank from
the adhesive container (or directly from the bag it comes in).
