The Nordson EcoDry
®
Compound Dryer is specifically
designed for smaller production lines with a wide range
of can ends. Nordson dryers are designed specially for
water-based end compounds using Nordson patented
induction-heating technology. These dryers require only a
fraction of the floor space of conventional dryers and are
economical to operate.
Nordson Advanced Induction
Nordson induction-drying technology heats only the can
end, not the air around them. Conventional hot air heating
systems heat the air surrounding the compound so the top
surfaces dry first causing blistering
as the trapped water inside the
compound escapes. Induction
heating allows compounds to dry
from the metal out making the drying
process faster and more complete.
Nordson dryers are ideal for both aluminum and steel
ends. All Nordson induction dryers use reliable, solid-state
components to provide controllable, even heating without
water-cooling. A simple blower cools all electrical components.
All Nordson dryers use reliable, solid-state
components to provide controllable,
even heating without water-cooling.
Energy Efficiency and Savings
The EcoDry compound dryer runs on a lower wattage than
standard dryers while 85 to 90 percent of the power consumed
is used directly to heat the ends, making it the economical
choice in smaller production environments. The system can cure
up to 475 can ends per minute (per lane).
Instant-on/instant-off heating not only gives consistent drying
for a quality product, but also contributes to energy savings by
substantially reducing energy waste by shutting off during line
stoppages. The EcoDry compound dryer starts instantly when
the line restarts and requires no preheating time, so energy is
used only when ends are in the unit.
Since the ends are not heating when the line stops, they do not
lose buckle strength, which is common with convection ovens.
Buckle strength drops when aluminum ends are held at high
temperatures for an extended period of time. The lighter weight
metals in use today are particularly sensitive to overheating.
Economical, Compact Size,
Straight-Through Design
The EcoDry compound dryer runs more efficiently, at a lower
wattage than our regular ICD-model dryers, and its compact
size allows for easy retrofit to existing end lines without major
modifications.
The straight-through tube virtually eliminates the problem of
line stoppages due to ends jamming in the dryer. Ends are
heated in stick, which protects the compound from damage
during drying. With many conventional dryers, the ends follow
a snake-shaped path inside the dryer, which can lead to line
jams and damaged curls.
Warm air is blown through the EcoDry’s heating tube while
the ends are heated inductively. The heated air, although not
needed to heat the ends, aids in the removal of water vapor
as it evaporates from the compound. Even without visible
separation, water evaporates and escapes from the slight gap
between ends. The flow of warm air in the tube continuously
removes water vapor and condensation, allowing the drying
process to continue rapidly.

Compound drying using induction heat
Simple, Automatic Operation
The EcoDry compound dryer is controlled by a PID closed-
loop temperature controller, which automatically controls the
correct heating of the ends with minimal operator intervention.
This provides consistent
drying without the seasonal
variations typical of convection
ovens. During start-up, a PLC
performs an extensive self-
diagnostic check for proper
operation of the unit.
The unit monitors the heating and safety components on a
continuous basis for safe, reliable operation. In the event of
an electronic malfunction, fault indicators on the control panel
are provided to identify the source of the malfunction for fast
troubleshooting with minimal downtime.
