The Duracraft™ design integrates Kanthal™ APM powdered-metal wire or helically wound heavy gauge conventional wire. Higher temperature operation is possible with the heavy-gauge wire.
The incorporation of self-locking ceramic spacers boosts reliability and consistency under fluctuations of repeated temperature cycling. Upgrading to Kanthal™ APM powdered-metal wire allows for the maximum temperature operation, longer element life, and large temperature swings.
Thermcraft manufactures ovens of all shapes and sizes.
