Superior Performance in Electric Heaters
Compacting with MgO is an innovative manufacturing technology that enables outstanding performance in the field of electric heating elements.
In the HD series, the resistive wire is wound around an MgO core and positioned very close to the outer tube of the element. This solution allows for extremely efficient heat transfer, keeping the wire at a lower temperature compared to conventional heating elements.
Thus, wire overheating during operation is avoided, which contributes to the high performance and durability of the product.
Caldor is the manufacturer, supplier, and distributor of these solutions
