Southwick & Meister, Inc, Meriden, Ct, has added a third Lucifer GT box furnace to their production capabilities.  As a major manufacturer of premium-quality collets, bushings, cutting tools, and more, Southwick & Meister uses Lucifer’s furnaces to heat treat under nitrogen atmosphere.
Model 7GT-H18 is fabricated from 10 gauge sheet steel reinforced with structural steel members continuously welded to form a solid shell for operation with a positive flow of inert atmosphere.  The 9”H x 12”W x 18”L chamber is lined with 5” of a combination of  lightweight firebrick hotface backed with coldface mineral wool for energy efficient operation and low outside shell temperature.  Powered with 9.5 KW and heating to 2100°F, the furnace heats by heavy-gauge coiled wire elements supported in high temperature cast monolithic holders which are easily replaced. A 1” thick cast hearth plate protects floor brick and supports the work load.  Temperature is regulated with a Honeywell DC2500 digital controller.  Add on features include an Overtemperature Safety System for unattended operation and a 7-day timer.  A representative of Southwick & Meister says “it’s been a great relationship for many years”, referencing Lucifer’s well built products and strong customer support.
