Lindberg/MPH Ships Treet-All Box Furnace to a Supplier of Sealing Products

Lindberg/MPH announced the shipment of a Treet-All box furnace to supplier of sealing products. The Treet-All box furnace is modular, stackable, and space-saving. It is ideal for tool room, plant maintenance, and production applications that require maximum heat-treating, hardening and tempering capabilities in a minimum amount of space. The Treet-All furnace is suited for multiple applications such as annealing, ashing, austempering, brazing, preheating, solution treating, stress relieving and normalizing.

The maximum temperature rating of this box furnace is 2050°F and the work chamber dimensions are 12” W x 18” D x 12” H. The work area temperature uniformity is ±25°F over the range of 1400° to 2000°F. An empty furnace can heat up in approximately 2.25 hours from ambient to maximum temperature. This is a significantly lesser time than typical operating temperatures. This furnace also features inert atmosphere capability.

 “At Lindberg/MPH our experienced team utilizes designs that minimize heat loss. For this particular box furnace, we used a vacuum formed ceramic fiber insulation to minimize heat loss and provide rapid heat up and control response.”- Kelley Shreve, Applications Engineer

Unique features of this Lindberg/MPH box furnace include:

  • Double steel shell construction assures a low temperature outer surface

  • Atmosphere tight, allow muffle

  • Heated by retained alloy resistive elements positioned on the roof, floor and both sidewalls to surround the workspace

  • Double side hinged insulated plug door keeps the inner – hot – surface away from the operator when opening to charge or unload work

  • Limit switch for power cut-off when door is open

  • Pre-wired, side mounted, forced air-cooled control console

  • Programmable controller

  • SSR solid-state relay fired heaters

  • Excess temperature controller connected to backup power disconnect

  • One dual thermocouple assembly

  • Power circuit breaker
