Buzzer
Fire-Box ™: from fine stock come endless varieties.
The versatile Buzzer Fire-Box family of furnaces includes a range of
models easily tailored to meet the individual needs of customers with
diverse applications. Some of our recent Fire-Box modifications, pictured
throughout this issue, include furnaces for both moderate (1,800 F) and high
temperature (2,150 F) applications, as well as furnaces equipped with
air-operated doors and roll-out quench tanks.
Who needs it?
For more than 50 years our Fire-Box type furnaces, sold primarily as “#57”s,
have been popular in both the fields of investment casing (dental, jewelry,
and industrial) and heat treating (hardening, pack carburizing, and
annealing.) They are also often used for tempering, assay work, low
temperature kiln work (cone 06 and lower), enameling, pre-heating, glass
work, and forging.

All Fire-Box style furnaces come equipped with our Buzzer Venturi
style gas burners. Our standard Buzzer equipment offers simple piping
and requires only low (household) pressure gas with no blowers, no
compressed air, and no forced exhaust. Our furnaces require only universal
120v/60Htz electric power, which greatly simplifies the installation of
microprocessor-based temperature and ignition controls: just plug in and go!
Stock models come with quality industrial firebrick insulation and
counter-balanced guillotine-style doors, and are rated from 500F to 2,150F.
We’re open to suggestions.
The real beauty of the Fire-Box family is how readily the stock models
welcome modification. We can make them taller, wider, downdraft,
fiber-lined, or rated for higher temperatures. We will be happy to assist in
designing the best furnace for your customer’s needs – it might very well be
a modified Buzzer Fire-Box!
