Pyramax Reflow Ovens
  • The standard for performance worldwide is defined by the Pyramax name.   Developed for very heavy backplane boards this family of ovens lives up to its motto every day: “Any board, any time, anywhere.”
High Temperature Belt Furnaces
  • BTU’s family of precision controlled high temperature belt furnaces surpass even the most challenging requirements of high-volume thermal processing.
  • Awesome precision and tight regulation is synonymous with Pyramax.  Its exclusive closed-loop convection technology consistently delivers the three things that create unmatched performance: thermal uniformity, atmosphere purity and very low exit temperatures.
  •  Expect astounding control of atmosphere, down to 2ppm O2 in the process zones.  This, combined with cross-belt uniformity exceeding +/-2°C, delivers amazing throughput and cycle time, without process yield loss over batch processes.
  • Highly controlled convection rates result in the same thermal process, line-to-line, factory-to-factory and site-to-site, on a global scale.
  •  Proudly manufactured in America for over 6 decades, BTU custom furnaces deliver peak performance and long-term reliability.
