Lindberg/MPH announced the shipment of an electrically heated cyclone pit furnace to a steel heat treater. This is a repeat customer for Lindberg/MPH and the pit furnace will replace an existing Lindberg furnace at their facility. The cyclone pit furnace will be used for a heat-treating process on aircraft components.

The maximum temperature rating for this electric pit furnace is 1250ºF. The work chamber has a 38" diameter x 48" depth and is constructed with an alloy liner backed with 7" of block insulation. The customer requested tight temperature uniformity and this design met a +/-10ºF temperature uniformity throughout the qualified work zone.  

The top load furnace features a thermocartridge recirculating fan and solid wall baffle for uniform heat distribution. The furnace fan utilizes a centrifugal blower type alloy blade and a 5 HP motor with belt and pulley drive system. The steel outer shell is constructed from heavy gauge steel plate reinforced with structural steel members.

“Ease of use and maintenance is always a top priority when we engineer equipment. This new Lindberg/MPH design features a maintenance friendly fan and motor assembly to provide reliable and easy maintenance when needed.” -Kenneth Zielke, Sales Engineer
