What Makes the QDS Series Unique?
The QDS Series Series Electric Dual Chamber Furnace is designed to deliver unmatched performance and reliability for a variety of demanding heat-treating processes.
- Dual Chamber Design •
- The dual-chamber design offers the versatility to perform multiple heat treatment processes simultaneously. This configuration enhances efficiency and allows for independent operation of each chamber, making it ideal for complex or sequential thermal cycles.
- Aluminum Processing •
- The bottom chamber features a recirculation baffle that shields parts from direct radiant heat, making it perfect for precise aluminum processing. This design ensures uniform heating and protection, ideal for applications such as annealing, tempering, and stress relieving of aluminum components.
- Space Saving Design •
- The over-and-under construction of this furnace series maximizes floor space by stacking two chambers vertically. This space-saving design is perfect for facilities with limited room, offering full functionality without compromising on performance.
Comprehensive Features for Optimal Performance
The QDS 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.
