What Makes the XLC Series Unique?
The XLC Series Series Electric Retort Furnace is designed to deliver unmatched performance and reliability for a variety of demanding heat-treating processes.
- Alloy Retort •
- This furnace features an alloy retort designed to contain the atmosphere, preventing oxygen infiltration and ensuring a very low dew point for cleaner, safer processing. Depending on size and temperature, the retort can be “D” shaped or corrugated for added strength, and is typically made from 330 Stainless Steel, Inconel 600, or Inconel 601, with other alloys available for specific applications.
- Combustible Atmospheres •
- This furnace is designed to operate in environments ranging from inert up to 100% hydrogen, enabling oxygen-free processing for sensitive parts. This capability ensures cleaner results and is ideal for applications that require a controlled, reducing atmosphere.
- Complete Safety System •
- Equipped with a comprehensive safety system, this furnace ensures safe operation when using combustible atmosphere. This built-in safety feature provides reliable protection, making it suitable for processes requiring stringent safety standards.
- Ceramic Element Holders •
- Proprietary high-temperature ceramic holders provide secure support for the heating elements, enhancing their radiating efficiency and longevity. The smooth surface prevents premature failure from thermal expansion, while the evenly spaced elements ensure superior temperature uniformity throughout the heating chamber.
Comprehensive Features for Optimal Performance
The XLC Series comes equipped with a robust set of standard features, carefully selected to ensure efficient and reliable heat treatment processes. For more specialized applications, optional features are available to enhance the machines capabilities and meet your specific requirements.
