Specifications
Available in various diameters, these heaters have specific voltage and amperage ratings, with a wattage tolerance of +5% to -10% and a length tolerance of ±2%. Proper fit and protection from contaminants are essential for optimal performance.

Ordering Information
When ordering, specify the diameter, sheath length, lead length, termination type, voltage, wattage, and any special modifications.

Special Modifications
Options include distributed wattage for localized heating, centerless grinding for precision, DURASLIK coating for chemical resistance, and various connectors and terminal boxes.

Cartridge Care and Maintenance
Store heaters in dry areas, protect leads from damage, ensure proper temperature control, and remove moisture by baking if necessary.

Termination Types
Available types include S1 (Standard Leads), F1 (Swaged-in Flexible Leads), TS (Teflon® Leads & Seal), R1 (Right Angle Leads), B1 (Straight Braid Lead Protection), and C1 (Straight Armor Cable).

DURASLIK Coating
This coating aids in the easy removal of heaters after use and acts as a corrosion inhibitor and lubricant.

Standard Cartridge Heaters
These heaters are available in various diameters and lengths, with specific wattage and voltage configurations. Part numbers are provided for ordering convenience.

MagnumTM Cartridge Heaters closing the loop on thermal solutions INTRODUCTION Magnum™ cartridge heaters are swaged designs, made for use in applications where high density, high temperatures and long service life are critical to minimize mold service downtime and expensive press open time. The swaged construction produces a highly compacted unit that resists shock and vibration, while providing for maximum element life through efficient transfer heating. They last up to 20 times longer than uncompacted cartridge heaters. Typical Applications • Liquid immersion • Plastic molds • Dies • Labeling • Medical equipment • Platens • Packaging equipment • Hot stamping • Sealing • Injection molding Design Features • Temperatures up to 1400°F (760°C) • Many standard diameters offered • Alloy sheaths • Highly compacted unit • Shock and vibration resistant • Custom manufactured to specifications • UL/cUL component recognition available • Metric sizes also available 190 Detroit Street, Cary, Illinois 60013 • Phone: 847-639-5600 • Fax: 847-639-2199 • Web: www.durexindustries.com • TOLL FREE: 800-762-3468
