DRYER OPERATION/

FEATURES

The TD4-400/500 dryer series is a four bed dryer design that
is ideal for use on large molding press or extrusion
applications. This large capacity dryer combines our patented
desiccant tower design and state of the art microprocessor
controls to provide a constant supply of dry air to the material
hopper. Material drying is controlled by utilizing one zone for
removing moisture from the process air, while regenerating
the other by heating the desiccant to a high temperature.
Once the regenerated beds cool down, the Zone Valve
switches the airflow, and the newly regenerated beds are used
to desiccate the process air stream. The saturated beds are
now regenerated in the same manner, completing the
regeneration cycle. The cycle is depicted Page 7.

The airflow design of the TD4 dryers makes the regeneration
cycle more efficient because we utilize a small amount of the
desiccated process air rather than ambient air to regenerate
the desiccant bed. This reduces the impact of the high
moisture content of the ambient air, which would contaminate
the desiccant bed, and allows the dryer to attain a lower dew
point. Please see the Air Flow Schematic on Page 6.

TD4 Design
Our patented TD4 design incorporates 4 double-stacked

desiccant beds . This nearly doubles the amount of desiccant
available for drying the process air stream, and because of the
tower design, the dryer is able to regenerate the desiccant in
the same time as our TD2 series. This allows the dryer to
operate in very high humidity conditions without affecting the
process air dew point. In fact, this design produces dew point
levels of – 40’ to -80’ C for faster more complete drying of your
material.

Unique to the TD4-400/500 disiccant bed design is the use of
two sets of desiccant towers per zone. The first tower in each
Zone Set is the regeneration cycle “control tower”, while the
second tower of the Zone Set is “slaved” off the first. Please
see the Air Flow Diagram on Page 7.

Hopper Design
These dryers are designed to be used with our large capacity

1000, 1500, and 2000 lb. hoppers. Our ”all stainless” hopper
design utilizes a stainless steel inner shell surrounded by a
stainless steel jacketed insulation layer. The easily removable
stainless steel spreader cone promotes proper material flow to
ensure that the material is dried efficiently and no undried

material is left at the hopper bottom that needs to be fed out
prior to operating. You must ensure that your hopper is
adequately sized for your usage rate and is kept filled, to
ensure that you have sufficient time to dry the material.

Dryer Controls
The TD4 series is supplied with the advanced Microprocessor

Control Module. The module includes a mother board, display
board and key pad that allow the operator to easily monitor
dryer performance and input operational settings.

The Microprocessor Control Module is one of the most
sophisticated yet operator friendly controls on the market. It
has many more features than other PLC and Microprocessor
controls currently available. This module provides the
operator with more control and operational flexibility with the
dryer. These features and the operating instructions are
covered in detail in the Microprocessor Control Instruction
Manual included with your dryer.
