USA Made Quality since 1950

BTU – Custom Furnaces Built in the USASince 1950 and with over 10,000 units shipped, BTU International has been the trusted name for high-tech customers with a need to solve high-volume thermal processing challenges. BTU’s custom high temperature belt furnaces have been manufactured in Massachusetts for over six decades with ISO 9001 quality certification safeguarding that each unit is subject to exacting build and test criteria. Today in the 100,000 sq. ft. state of the art manufacturing facility, craftsmen with decades of experience ensure the highest quality performance and reliability from our custom furnaces.BTU Fast Fire belt Furnace

Continuous belt furnaces from BTU are known for long-term reliability, superior process performance, and service excellence. In partnering with BTU, manufacturers can expect a customized furnace solution that will exceed expectations, not only for process performance but for reliability and usable life-time.

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 lengthTypical Brazing Thermal Profile
  • 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.
