Thermcraft Inc products

These cylindrical heaters use a helically wound iron-chrome-aluminum wire partially embedded in the ceramic fiber. Leads can be standard (single strand) or braided (two strands twisted). The heaters are available with intregal vestibules with the opening sized to meet the need of the application.

The Duracraft design incorporates helically wound heavy gauge conventional wire or Kanthal APM powdered-metal wire. The heavy gauge wire enables higher temperature operation. The addition of self-locking ceramic spacers increases consistency and reliability under fluctuations of repeated temperature cycling. Upgrading to Kanthal™ APM powdered-metal wire allows for the highest temperature operation, large temperature swings and longer element life.
