4 | THESCHAEFERGROUP.COM Custom Designed Furnaces and Systems Since 1970, The Schaefer Group has developed custom aluminum furnaces for die casting, permanent mold and sand foundries. We specialize in electric, gas, and propane as well as combination fuel furnaces for melting, holding and transfer. We also custom design launder systems, crucibles, filtration and degassing systems. Our re-line and repair services can retrofit existing furnaces as well. We have probably custom designed more molten metal delivery systems than anyone else in the world. Over 50 years of experience makes Schaefer Furnaces the experts in Profitably Casting Your Bottom Line! Electric Aluminum Melting Furnaces The Schaefer Group developed the world’s first electric reverbatory (wet bath) furnace in 1974 and the rest is history. This furnace is now the industry’s first choice for low cost production of clean molten aluminum. Our highly efficient electric reverberatory melting furnaces provide the best quality metal from ingot or scrap. And, they have an extremely low metal melt loss and are easy to operate and maintain. Melt loss is so low with this furnace (often less than 1%) that those savings alone typically provides a one year (or less) return on investment! ADVANTAGES: • Excellent Metal Quality — no combustion means no metal gassing and a conservatively-sized tranquil bath eliminates oxide-creating metal turbulence. • Melting — silicon carbide resistance elements transfer radiant heat to the work load to melt metal with only 0.20 to 0.23 KWH per pound. You can even melt efficiently from a cold start. A full-proportioning control system delivers accurate energy flow. • Melt loss — typically less than 1%. • Cleaner heat — means a cleaner work space. • Sustainability — no output of hot fuel gasses to heat up the environment means reduced carbon footprint.
