Ordering Information: Please specify OD (Outer Diameter), HZ (Hot Zone length), CZ (Cold Zone length), and OL (Overall Length). Special resistance requirements should be communicated during ordering.

Applications

Suitable for furnace applications operating at 600-1600°C. Can be used directly in air atmosphere without protective gas. Widely used in metallurgy, ceramics, glass, machinery, analytical testing, semiconductor, and research applications.

Installation & Usage Guidelines

Protect heaters from moisture during storage and installation
Group heaters by resistance tolerance (within 10%) for even load distribution
Handle with care during assembly and maintenance due to brittle nature
Gradually increase voltage during initial operation; avoid full load immediately
Replace damaged heaters following resistance increase patterns
