Description
The D215 Hot Melt Unit is a light-duty to medium-duty machine used for melting and pumping a
variety of materials. The melt unit consists of a heated melt tank and a motor-driven, positive
displacement V4 series gear pump. The melt unit is compatible with a variety of Astro Packaging
pattern generators and head drivers.
The D215 Hot Melt Unit is all-electric and accepts standard forms of adhesive. The unit is equipped
with a
fl ow control valve for fl uid pressure and fl ow regulation. The melt unit has a 6.82 kg (15 lb.)
tank capacity, and supports 1 or 2 automatic or manual applicators and hoses.
All zone temperatures range from 4 °C (40 °F) to 232 °C (450 °F), adjustable by a TC500
Temperature Controller. An integral melt grid is standard.
Electrical power to the melt unit is controlled by a power-disconnect circuit breaker located on
the front end of the melt unit.
Features
• The solid-state Temperature Controller uses Resistance Temperature Detector (PT 100 RTD)
sensors to sample and regulate temperatures in the tank, hoses and applicators.
• Circuit breakers and fuses protect the entire system from overload.
• A tank-mounted over-temperature thermostat switches the system power o
ff in the event of a
tank controller failure.
• A circuit breaker protects the pump motor by switching the motor o ff should a stall or an
overload condition occur.
• TC500 Temperature Controller protects pump/motor from starting before the material in
system is Run-Ready.
• TC500 Temperature Controller provides a 7-Day Scheduler to Automatically turn the system On
and O ff once per day.
•TC500 Temperature Controller provides over-temperature protection to all zones and will shut
down the main circuit breaker if a temperature zone is over temperature.
