Electric Furnaces

Our electric furnaces are specially designed to fill the needs of the studio artist, schools and universities. Quiet, clean and safe. These electric furnaces are highly efficient and designed for constant use and long life. The crucible is investment cast to afford thermal stability. The heating chamber rests on top of the crucible casting. Each can be replaced independent of the other. The door is counter balanced and easily opened and closed with one hand. A leveling switch shuts off the power to the heating elements when the door is opened. A pilot light indicates when power is being supplied to the heating elements and an hour meter shows the commutative hours power has been applied to the elements. Each model is equipped with a venting system to allow caustic fumes to escape and prolong element life. The side mounted control panel comes standard with a digital, multiple ramp & soak point set controller. A high quality R type thermocouple is standard on all models. The outer steel skin of the furnace is in three pieces with a removable back panel to access the crucible and upper heating chamber. The elements are constructed of Kanthal A1 resistance wire (APM elements optional). Foreign models are available, specify electrical requirements when ordering. Not available in 3 phase electrical.

Furnace Elements

We offer two types of resistance wire elements. Our standard alloy (Kanthal A1) elements for temperatures up to 2200° F (1200° C) and a new alloy (Kanthal APM) for temperatures and atmospheres that conventional alloys cannot handle. This delivers improved stability with virtually no scaling.

Kanthal A1

These furnace elements have approximately a four to five month life. It is advisable to keep a spare set on hand.
