Cartridge Heaters-Redrodä

INTRODUCTION

REDRODä "R" SERIES HIGH WATT DENSITY

AKINSUN High watt density cartridge heaters are manufactured to the highest industry standards using only premium materials. Our tight manufacturing controls results into uniform surface temperatures and resistance to oxidation and corrosion even at elevated temperatures. " R " series cartridge heaters are designed for higher temperatures, longer life even in the most severe, rugged and demanding applications. Their heavy duty, construction provides high dielectric strength as well as shock and vibration resistance.

Features

Incoloy or Stainless Steel Sheath: Selected heavy wall tubing gives maximum heat transfer, high compaction, and is corrosion resistant.

Lava Cap: With its high density or the ceramic cap locks the magnesium oxide in place, acts like an insulator between pin and sheath and also resists contamination.

Leads: Flexible, non-asbestos fiberglass leads crimp connected mechanically.

Swaging: Maximum swaging results in greatest cross section reduction of area, offering virtual conduction for highest watt densities.

Centering: Mgo spacer precisely centers the wire wound core eliminating hot spots.

AKINSUN cartridge heaters have been in use in various applications for years. Successful application depends on proper installation of heater, operating temperatures and heater watt density.

Application of Redrodä Cartridge Heaters in Platens, Dies, and Molds
When selecting cartridge heaters for above application the following factors are checked to insure the heater will experience longest possible life and provide sufficient heat for the job.

Heater Watt Density

Proper Fit of Heater

Proper measures against contamination

Sufficient KW to heat and to compensate for heat losses
