WARNING: Never disarm diagnostic devices including but not limited to:
SCurrent sensor
SOvertemperature switches
SAir pressure switch
SCoil tray lid safety switches
Disarming diagnostic devices will void the warranty and may cause
equipment failure.
Personal Safety
To prevent injury follow these instructions:
SDo not operate or service equipment unless you are qualified.
SDo not operate equipment unless safety guards, doors, or covers are
intact and automatic interlocks are operating properly. Do not bypass or
disarm any safety devices.
SMake sure that the ventilation system is operating properly to prevent
dangerous concentrations of volatile particles or vapors.
SKeep clear of moving equipment. Before adjusting or servicing moving
equipment, shut off the power supply and wait until the equipment
comes to a complete stop. Lock out power and secure the equipment to
prevent unexpected movement.
SDisconnect, lock out, and tag switches before servicing electrical
equipment.
SKeep parts of your body and metal implements away from the induction
heating zone while the system is energized. Metal objects will heat up
very quickly. Remove all jewelry, watches, and rings.
SObtain and read Material Safety Data Sheets (MSDS) for all materials
used. Follow the manufacturer’s instructions for safe handling and use
of materials, and use recommended personal protection devices.
STo prevent injury, be aware of less-obvious dangers in the workplace
that often cannot be completely eliminated, such as hot surfaces, sharp
edges, energized electrical circuits, and moving parts that cannot be
enclosed or otherwise guarded for practical reasons.
SHearing protection is recommended.

Fire Safety
To avoid a fire or explosion, follow these instructions:
SAll equipment must be grounded and bonded to the building ground.
SDo not heat materials to temperatures above those recommended.
Make sure heat monitoring and limiting devices are working properly.
SProvide adequate ventilation to prevent dangerous concentrations of
volatile particles or vapors. Refer to local codes or your material MSDS
for guidance.
SDo not disconnect live electrical circuits while working with flammable
materials. Shut off power at a disconnect switch first to prevent
sparking.
SKnow where emergency stop buttons, shutoff valves, and fire
extinguishers are located.
SClean, maintain, test, and repair equipment according to the instructions
in your equipment documentation.
SUse only replacement parts that are designed for use with original
equipment. Contact your Nordson representative for parts information
and advice.
Action in the Event of a Malfunction
If a system or any equipment in a system malfunctions, shut off the system
immediately and perform the following steps:
SDisconnect and lock out system electrical power.
SIdentify the reason for the malfunction and correct it before restarting the
system.
Disposal
Dispose of equipment and materials used in operation and servicing in
accordance with applicable laws, regulations, or codes.

Description
See Figure 1. The Nordson EcoDry 2 Series Induction Dryers provide
simple, efficient, and uniform drying of water--based end--sealing
compounds applied to can ends. The dryers use solid--state induction
heating to generate heat within the can ends and dry the sealing compound,
at line speeds of up to 2200 ends a minute. The dryers can be designed for
can end diameters from 57 to 110mm.
The dryers are available with single- or dual-channels and can be
configured to mate to almost any line height. Each dryer is designed to
handle a particular material and can end size or limited range of can end
sizes, according to the customer’s specifications.
Figure 1 EcoDry 2--9 Series Induction Dryer
Heading
Instant On / Off When the line starts, heating within the can ends instantly starts. Since heat is
created directly within the ends, there is no thermal inertia. When the line
stops, heating instantly stops. This produces a very uniform product.
No Jams The short length of the dryer and the straight-through design minimizes jams.
Energy Savings Solid state induction heating is extremely efficient. Greater than 80% of the
power consumed is directly realized as heat in the can ends. When the line
stops, almost no power is consumed.
Reliability The solid-state design of the dryers minimizes downtime. There are few
moving parts to wear out.
Small Footprint Because induction drying is so effective, the dryer is much smaller than
conventional ovens.
Temperature Control The dryer continuously monitors the temperature of the can ends as they exit
the dryer and adjusts coil power to maintain the desired set point temperature,
providing uniform control of product quality.
Magnetic Separator An optional magnetic separator can be installed at the dryer exit.

Item
1Motion Sensor: A laser sensor that monitors the movement of can ends at the entrance to
the dryer. The controller will only apply power to the induction coil when the motion sensor
detects can ends moving through the dryer.
2Coil Tray: Contains the induction coil, glass coil tube, auxiliary air heater, heater blower, and
exhaust blower. The can ends travel through the glass tube and are heated by the induction
coil. Cabinet air is heated and forced through the tube to carry off the moisture vaporizing out
of the sealing compound. The exhaust blower draws the heated air and moisture out of the
tube. The coil tray attaches to the customer infeed and outfeed system.
3Operator Control Console: Contains the operator interface terminal (touch screen) which
contains all operator control functions including warnings and faults. The console includes an
Emergency Stop button and system on/off push-buttons.
4Control Enclosure: Contains the system controller (PLC), cooling air filters and fan, and
power inverter devices and circuit boards.
5Temperature Sensor: Senses the can end temperature as the ends exit the coil tray. The
temperature controller then regulates the power applied to the induction coil to produce the
desired can end exit temperature. The sensor is a low-mass Type-K thermocouple.

Theory of Operation
See Figures 3 and 4.
The can ends move through a glass coil tube inside the coil tray. The tube
is surrounded by the induction coil. As can ends enter the dryer, the motion
sensor at the entrance signals the controller. The controller causes the
power inverter to apply alternating current to the coil windings. The coil
windings generate an alternating magnetic field that creates large eddy
currents in the can ends. The resistance to the eddy currents generates
heat within the can ends and dries the sealing compound. If the can end
line stops, the motion sensor signals the controller, which shuts off power to
the coil windings.
The temperature sensor (thermocouple) at the exit senses the can end
temperature and signals the temperature controller, which adjusts the power
going to the coil windings to maintain the temperature at the set point. The
controller uses a PID (Proportional--Integral--Derivative) algorithm that
automatically adjusts the amount of power supplied to the coil to eliminate
temperature variations due to line voltage fluctuations, applied compound
weight, and can end start temperature.
A blower in the controller/power inverter enclosure pulls in room air and
directs it over the electrical components to cool them. A second blower in
the coil tray cools the induction coil. An air heater mounted on the tube hub
at the entrance end of the coil tray interior then adds additional heat to the
air as it enters the coil tube to carry off moisture vaporizing out of the
sealing compound. If an optional magnetic separator is installed at the tube
exit, heated air is also ducted directly into the separator.
Safety interlocks include thermocouples, and a pressure switch. A
customer interlock is also provided. Interlock status is indicated on the
operator control panel.
