The Mentor Vacuum Furnace

The Mentor® Vacuum Furnace

Compact, economical production furnaces

The Mentor®, Model HFL-2018-2IQ, is a horizontal, front loading, compact, vacuum heat treating and brazing furnace generally designed and developed to accommodate small to mid-size furnace loads in an efficient and economic manner. It is a high temperature, high vacuum, batch-type furnace with electrical resistance heating elements. The Mentor® is mounted on a single, portable platform for easy shipment and maneuverability.  Designed for heat treating, hardening, brazing, stress relieving, normalizing, annealing, tempering, sintering, homogenizing, degassing, diffusion bonding, creep forming.

  • Oversized water inlets and outlets assure maximum water flow


Gas Quenching System

  • The internal gas quench system provides the lowest resistance, highest efficiency gas flow in the industry.
  • A 7.5 HP motor drives a high-speed turbine fan to recirculate the quench gas straight through the water-to-gas heat exchanger and then into the hot zone at high velocity.
  • The tapered graphite gas nozzles are specifically directed at the work load for optimum cooling.


Vacuum Pumping System

  • Mechanical Pump: High capacity rotary vane pump
  • Diffusion Pump: Varian VHS-6 6″
