Can-End Induction Sterilizer Compact, energy-efficient sterilizing system for steel can ends. ■ Induction heating process heats only the ends, not the air around them, for fast, energy-efficient ■ Air-cooled, medium-frequency induction process provides a simple, safe and reliable sterilization system. ■ Temperature sensor guards against under- temperature ends. ■ Instant on/instant off operation saves energy. ■ Temperature and power control for consistent performance. ■ Solid-state components for reliable operation. ■ Automatic frequency tuning. The Nordson can-end sterilizer utilizes patented medium- frequency induction heating to sterilize steel can ends simply, safely and efficiently with minimum operator intervention. The system requires less space, energy and maintenance than conventional sterilization systems. Innovative Induction Technology With medium-frequency induction heating, power is supplied to a series of coils, creating a fluctuating magnetic field. Steel can ends that pass through the coils are heated directly by the eddy currents produced within the steel. The system provides fast, controllable heating with less energy consumption than other heating methods. The induction coils are wrapped completely around a Pyrex* transport tube, through which the ends are conveyed. The transport tube isolates the ends from the induction coil, and protects the coil from direct contact with the parts. Energy requirements for these induction-heating systems are typically * Pyrex is a trademark of Corning Corporation. ADVANCED INDUCTION 70 percent less than conventional gas heating systems. In addition, the instant on/off heating also contributes to energy savings. The system's solid-state, power-generating components convert approximately 90 percent of the energy consumed into usable heating. In addition, the end sterilizer also has a low-power standby feature that keeps ends at their proper temperature during line stoppages, reducing energy waste substantially by not operating at full power. Medium-frequency (5-15 kHz) power generator and control components are located directly under sterilizer coil tray in a 30 X 42" enclosure. A base-mounted blower cools all electronic components. Exhaust air from the generator is directed through the coil enclosure to cool the induction coil. No water cooling Each power generator can deliver up to 30 kilowatts of energy, depending on the line voltage.

Can-End Induction Sterilizer System Components The can-end sterilizer is a compact system that includes a control panel, medium-frequency power generator and an enclosed coil assembly. The system is approximately 1.24meters in length and can sterilize 600 ends per minute in a single channel. An EST 6 system can sterilize 800 ends per min in apx 1.8 m System Operation Ends are conveyed in-stick into the sterilizer using existing conveyors or optional Nordson-provided conveyors. The frequency range needed to heat the ends typically ranges which creates a deep heating effect that A temperature sensor...
