Globar® heating elements


Globar® Glass Seal is part of the Globar® Precision family of state-of-the-art silicon carbide (SiC) heating solutions, each of which has been developed for use in specific atmospheres and conditions.

Globar® Glass Seal has been specifically designed for the very toughest operating conditions. It delivers longer element life, reduced need for maintenance, fewer shutdowns and enhanced quality and process stability, compared with standard products.

Globar® Glass Seal is interchangeable with existing products and can be applied to all heating element types within the Globar® range, making it suitable for both new and existing applications.

Protective Globar® Glass Seal adds many benefits

By choosing Globar® Glass Seal, customers will benefit from all the advantages offered by the product, which protects the element from chemical attack and particularly inhibits water vapor attack. The protective seal enables the element to withstand aggressive applications and delivers a product lifetime that can be up to three times longer than that of an unprotected element. It also reduces the need for replacement and therefore minimizes downtime while ensuring temperature uniformity for longer periods of time. This enables customers to improve yield and product quality from the furnace. in the furnace.
