Custom Belt Furnace Configuration
BTU’s custom belt furnaces come in two basic configurations: muffle or muffle-less. A muffle furnace is typically used in applications where control of temperature and atmosphere are of utmost concern – or for special process atmospheres such as Hydrogen. A muffle-less furnace has operational advantages for use cases where the furnace will be heated up and cooled down frequently while still providing precise control of temperature and atmosphere.
The features and characteristics of the belt furnaces that are usually customized based on the customer’s application and throughput needs are:
- overall furnace length
- maximum process temperature
- process chamber width and height (clearance)
- number of heated zones
- cooling length and zones
- belt loading
- atmosphere capabilities including control and safety considerations
BTU’s sales and applications teams will work with customers to configure the best possible custom belt furnace for each application. In some cases product trials will be run at our facility in Billerica, MA, USA. In many cases we will be able to offer suggested furnace configurations for common product/profile combinations. Key inputs to the configuration process of a custom belt furnace include: product size and weight, thermal profile, throughput requirements, available factory space and atmosphere requirements.
Advanced Analytical/Modeling Capabilities
BTU’s experienced team of engineers employs the latest technology in furnace system design including CAD, Finite Element Analysis, and Computational Fluid Dynamics. These advanced techniques accelerate the development process while reducing errors and variation in design. In partnership with customers, these tools can be used to analyze and solve the most complex thermal processing challenges resulting in the world’s best performing custom continuous belt furnaces.
BTU’s ovens and furnaces are the industry’s process and productivity leaders and have tens of thousands of installations. Contact BTU with any questions or to learn about the latest advancements in reflow ovens, furnaces or SMT technology.
HIGH-VOLUME CONTINUOUS THERMAL PROCESSING EXPERTS – FROM PILOT TO PRODUCTION
BTU’s atmosphere furnace is available with temperature ranges up to 1800°C and with various process atmospheres including hydrogen, nitrogen and argon. Excellent atmosphere purity is controlled atmosphere furnace achieved through the use of BTU’s patented gas barrier technology. BTU employs multiple heating technologies including: IR, and convection (high and low temp). Inline processing can increase throughput by 4X over other methods.
