Introducing the
DMZ2 Dehumidifying Dryer.
Versatile, high performance
in a compact, portable design. dmz2 series
Only from Matsui.
packed with performance
The DMZ2 is the ideal dehumidifying dryer to inte-
grate with your central loading system or to handle
multiple hoppers. It offers more features as stan-
dard equipment with a smaller footprint than com-
parable systems, giving you maximum performance
in minimal space.
virtually maintenance-free
The DMZ2’s rotor has a 15-year life, designed to run
without replacement. Heater circuits have solid-
state relays, providing 10 years of maintenance-free
operation. Routine maintenance can be performed
from the front of the system, quickly and easily.
ideal for pet bottle production
The ideal unit when exceptional quality is impera-
tive, the DMZ2 maintains stable IV and low AA lev-
els, and brings moisture content below 50 ppm. It
can dry PET in as little as 3 hours and has through-
put up to 1500 kg/hr and larger.
high performance hopper design
The DMZ2’s drying hopper uses a
unique diffuser-cone technology to
create mass flow with no short
pass. This ensures all resin leaving
the hopper is consistently dry and
up to temperature. Smaller units have a
tilt-open feature to make cleanups and
resin-changes fast and easy.
touchpad programming
An easy-to-use touchpad simplifies programming,
enabling you to preset operations, monitor settings,
view progress and make changes effortlessly.
energy-saving production
Insulated stainless steel construction prevents heat
loss, and while drying resin in half the time, it saves
hours of energy with every material change.
Take a look at what the new DMZ2 offers:

Matsui’s desiccant rotor technology has become the
industry standard in dehumidifying hot-air drying equipment.
Its unique, honeycomb design—molecular sieve desiccant, bond-
ed and then baked onto ceramic paper—eliminates powder that
can contaminate the system. Its large contact area effectively
absorbs at high temperatures, drying resin in half the time while
stabilizing dew points at a constant –40˚F.
