BTU’s experienced team of engineers employs the latest technology
in system design including CAD, Finite Element Analysis, and Compu-
tational 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 continuous furnaces.
Temperature Control
BTU’s muffle furnaces maintain temperature uniformity by utilizing
automated thermal controls and segmented programmed and con-
trolled by the WINCON
™
system software.
• Equipped with top and bottom heaters (side heaters optional)
• ±2°C across belt uniformity typical

Atmosphere Control
Advanced Analytical/Modeling Capabilities
The Controlled Atmosphere Furnace from BTU features precise at-
mosphere controls to monitor critical parameters within the process
chamber. The gas control panel is designed to operate in a safe/ failsafe
manner while minimizing operator intervention.
• Achieves O

purity of 95%
• Optional gas barriers provide isolation of gases for maximum atmo-
sphere control
• Monitoring devices for ow and pressure confirm adequate gas supply
• Gas safety system monitors ignitors to ensure spent process gas is
combusted prior to entering the atmosphere (Hydrogen or reducing
atmosphere)
