THE DRUM
The drum is made of ST44 drawn steel pipe and
all standard models are finished with surface
grinding. On request the drum surface can
also be plated with either chrome or Teflon.
Inside the drum is one single heating unit that MM
consists of three pieces. The drum is filled with
transfer heating oil that fills up 60% of the inner
volume. The failsafe-switch mechanism helps
balance the inner pressure, and will deactivate
the machine should there be any issues
regarding the gasses generated by heated oil
so to avoid injury or damage. The heat sensor is
placed on the surface of the drum, this enables
more accurate readings and provides better
print results. Maximum Working Temperature
and Temperature Restrictions can be easily
adjusted via the Touch-Screen Panel.

THE FELT BELT
All of our machines are equipped with 100% Nomex seamless industrial felt belts that are reinforced with
Kevlar material in order to avoid stretching. The expected lifetime for the belt on this unit is between 3
& 5 years depending on use. In order to eliminate movement of the felt belt to either side the machine
is built with an automated-felt centering mechanism. The felt tension and the felt centering system are
both air-operated (Pneumatic). Should the compressor fail to supply the required air for the system, the
machine halts and alerts the operator to prevent lasting damage to the belt.
