Electric Crucibles
Melting or holding, these popular furnaces deliver exceptional efficiency. With covers on, they use only 0.20 to 0.25 KW/hr per pound to melt cold metal and just 3 to 4 KW/hr to hold 1,000 pounds of molten aluminum at 1,220 degrees Fahrenheit. Electric crucibles use less energy than channel-type induction furnaces, and they provide more accurate temperature control. Both manual and power-operated tilt-type versions are also available. |

| The Schaefer Group, Inc. provides furnaces for melting, holding degassing and filtering molten aluminum. We provide mlten mtal transfer by designing highly efficient launders and ladles. We design either electric or gas fired furnaces with "Super Insulated linings" and our elecrtic immersion element furnaces are some of the most efficent on the market. In short we design soffisticated molten metal melting and delivery systems and single small furnaces for die casters. The same engineering approach is used in both large systems and small furnaces. Let us build out highly efficient furnaces for you! |

Electric or Gas Fired
A 2,000 pound (907.2 kg) Schaefer electric holding furnace will maintain a temperature of 1,300 degrees Fahrenheit (704.4 degrees Celsius) for only 3 KW/hr (2,581.2 kcal/hr) with well covers on. You get similar savings in all capacities, from 1,500 (680.4 kg) to 8,000 pounds (3,629 kg).
We offer a choice of ni-chrome or silicon carbide heating elements. Ni-chrome lets you use a lower-cost control system; silicon carbide handles higher watt loads for more compact furnaces.
If you prefer to use gas, you can hold those 2,000 pounds (907.2 kg) at 1,300 degrees Fahrenheit (705 degrees Celsius) with 50 to 60 CF gas/hr (12,660-to-15,120 kcal/hr). We can also supply a dual energy option that lets you convert between electricity and gas to use the lower cost source.
Lining - We offer a choice of either monolithic or board lining systems. Our rugged, thermally efficient, non-wetting lining lets us put the hot metal well anywhere you want it. And we can make it square or rectangular, straight or offset at special angles, even with sloped ends for robot ladling and other automation equipment. The lining also helps keep the casing temperature low.
Options - A power-operated tilt lid lets you clean the furnace in less than 10 minutes. And we can apply full-proportioning, solid-state microprocessor controls and specially designed heating elements with a proven record of superior service life. |

Highly efficient electric reverberatory melting furnaces provide the best quality metal. They have an extremely low metal melt loss. They also have very low maintenance requirements.
Ever since Schaefer designed, built and installed the world's first one in 1974, the radiant electric reverb. has become many melter's first choice for the low cost production of clean molten aluminum. Approximately eighty-five percent of the electric reverb furnaces working today carry the Schaefer nameplate.
Versatility
These production melters meet the needs of a variety of metal casters, high and low pressure die casters, and permanent mold, sand, investment and plaster mold foundries around the world.
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 is usually less than 1%, AND THAT ALONE CAN GIVE YOU A ONE-YEAR RETURN ON INVESTMENT.
Metal Quality
Electric wet bath reverbs deliver the finest metal quality from ingot or scrap. No combustion means no metal gassing, and a conservatively sized tranquil bath eliminates oxide-creating metal turbulence. If you need the high metal quality, ask us about filtration and other processes that will deliver exact metal grades.
Operating Comfort
Schaefer Electric reverbs are quite. They don't put out hot fuel gasses to heat up the environment. Their cleaner heat also means a cleaner work space. |

The PAM Furnace uses an electric arc between a water-cooled torch and the material to be melted to add energy in an non-reactive furnace environment (usually argon or helium).
These furnaces melt both reactive and refractory metals.
Plasma Arc Melting systems improve the properties of conventional and otherwise impossible-to-melt alloys thus allowing for qualification and production of titanium used for rotating parts in aviation and land based turbines.
