Can-End Induction Sterilizer

nnnn

Compact, energy-efficient sterilizing system for steel can ends.

nnnn

Features and Benefits

nnnn

■ Induction heating process heats only the ends,

nnnn

not the air around them, for fast, energy-efficient

nnnn

heating.

nnnn

■ Air-cooled, medium-frequency induction process

nnnn

provides a simple, safe and reliable sterilization system.

nnnn

■ Temperature sensor guards against under-

nnnn

temperature ends.

nnnn

■ Instant on/instant off operation saves energy.

nnnn

■ Temperature and power control for

nnnn

consistent performance.

nnnn

■ Solid-state components for reliable operation.

nnnn

■ Automatic frequency tuning.

nnnn

The Nordson can-end sterilizer utilizes patented medium-

nnnn

frequency induction heating to sterilize steel can ends simply,

nnnn

safely and efficiently with minimum operator intervention.

nnnn

The system requires less space, energy and maintenance than

nnnn

conventional sterilization systems.

nnnn

Innovative Induction Technology

nnnn

With medium-frequency induction heating, power is supplied

nnnn

to a series of coils, creating a

nnnn

fluctuating magnetic field. Steel

nnnn

can ends that pass through the

nnnn

coils are heated directly by the

nnnn

eddy currents produced within

nnnn

the steel. The system provides fast,

nnnn

controllable heating with less energy consumption than other

nnnn

heating methods.

nnnn

The induction coils are wrapped completely around a Pyrex*

nnnn

transport tube, through which the ends are conveyed. The

nnnn

transport tube isolates the ends from the induction coil, and

nnnn

protects the coil from direct contact with the parts. Energy

nnnn

requirements for these induction-heating systems are typically

ADVANCED INDUCTION

nnnn

70 percent less than conventional gas heating systems.

nnnn

In addition, the instant on/off heating also contributes to

nnnn

energy savings.

nnnn

The system's solid-state, power-generating components convert

nnnn

approximately 90 percent of the energy consumed into usable

nnnn

heating. In addition, the end sterilizer also has a low-power

nnnn

standby feature that keeps ends at their proper temperature

nnnn

during line stoppages, reducing energy waste substantially by

nnnn

not operating at full power.

nnnn

Medium-frequency (5-15 kHz) power generator and control

nnnn

components are located directly under sterilizer coil tray in a

nnnn

30 X 42" enclosure. A base-mounted blower cools all electronic

nnnn

components. Exhaust air from the generator is directed through

nnnn

the coil enclosure to cool the induction coil. No water cooling

nnnn

is required.

nnnn

Each power generator can deliver up to 30 kilowatts

nnnn

of energy, depending on the line voltage.
