Are you looking for 1:1 diffusion heater element retrofit? Do you want OEM quality and fast delivery?
For more than 40 years Thermcraft supplies high quality semiconductor replacement diffusion heater elements to the semiconductor industry, using knowledge gained from all facets of thermal engineering. We offer custom designed diffusion heating elements and 'plug and heat' solutions for most existing horizontal or vertical diffusion furnace heaters. As 1:1 heater element retrofit or for new applications. Diffusion Duracraft™ series heating elements are heavy gauge APM wire type elements, similar to most standard diffusion heater elements for operating temperatures up to 1300°C (2460°F). Rapid delivery and off-the-shelf pricing make these elements the cost-effective solution for your semiconductor heating needs. We offer diffusion furnaces elements, refurbishing and heater element accessories including standard and custom sized vestibule blocks are available as well as diffusion furnace collars and discs.

Why self-locking comb spacers extend the lifetime of your diffusion heating element?
Self-locking comb spacers lock together around the circumference of the element, maintaining constant coil spacing and total support of eacht turn of the resistance coil. This design keeps the spacers in place throughout repeated temperature cycling.
