The Mentor® Pro Vacuum Furnace

Compact, economical production furnaces

The Mentor® Pro, Model HFL-3036-2IQ, is a horizontal, front loading, compact, vacuum heat treating and brazing furnace generally designed and developed to accommodate mid-size furnace loads in an efficient and economical manner. It is a high temperature, high vacuum, batch-type furnace with electrical resistance heating elements. The Mentor® Pro is mounted on a portable platform for easy shipment and maneuverability. Designed for heat treating processes such as hardening, brazing, stress relieving, normalizing, annealing, tempering, sintering, homogenizing, degassing, diffusion bonding, creep forming.

 Hot Zone

  • Hearth: TZM molybdenum support pins and rails
  • Heating Elements: curved, segmented graphite bands
  • Insulation: Four layers of 1/2″ thick high purity rayon graphite felt with a Flexshield hot face
  • Insulation and heating elements are mounted on a heavy duty (0.090″) stainless steel support structure

 

 Power Supply

  • MSI SCR power supply rated at 75 KVA 415 / 460 volt / 3 phase / 50 or 60 Hertz

 

 Vacuum Chamber

  • Carbon steel, double wall, water cooled, horizontal front loading vacuum chamber
  • Autoclave locking ring, front door allows the furnace to safely quench at positive pressures up to 2-bar
  • 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 at positive pressures up to 2-bar.
  • A 50 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, 2-stage, rotary piston pump
  • Diffusion Pump: Varian HS-10-10″
  • Holding Pump: High capacity rotary vane pump
  • High Vacuum Valve: 10″ Right angle poppet valve

 

Control Cabinet and Instrumentation

The SolarVac® Essentials is a PLC based control system with operator interface, recipe storage, alarm management, and data acquisition functions. Enables the operator to monitor, control, record, and quickly understand the status of the furnace operation. All controls and instrumentation are housed in a suitable NEMA 12 control cabinet.

  • HMI Operator Interface: Industrial PC with large, color touchscreen mounted on a swing-arm assembly. Utilizing supervisory-level HMI software to display information and diagnostic messaging graphically.
  • Programmable Logic Controller: Allen-Bradley CompactLogix
  • Overtemperature Controller: Honeywell Model UDC2500
  • Graphic Video Recorder: Eurotherm Model 6100A utilizing a color touchscreen
  • Vacuum Instrumentation: Televac with active gauge heads
  • Control Thermocouples: Type “S”
  • Work Thermocouples: Type “K”
