Accessories
Pneumatic by-pass valve pressure control system
The equipment’s by-pass valve provides an important safety feature, as it
limits the maximum pressure in the system, especially during continuous
pumping periods with closed applicators.
This valve may be a manual adjustment valve, using a threaded screw, or
with pneumatic control, using a pressure regulator and a pressure gauge. In
the latter case, the adhesive circuit pressure has a 1:13 ratio to the hydraulic
pressure.
Light tower system
Two colors light tower system, white and green for alarm signals of ‘low level’
and‘unit ready’ respectively.
Level control system
To control the hot-melt level from the control card display screen or from the
main machine, using the NO (normally open) contact, with no voltage.
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 sensor 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).
