Kanthal A-1 Elements or same Grade.
The elements are coiled Kanthal A-1 Elements. We always
best low watt density is used for long element life.
Side wall, Back wall, door, Bottom five side Elements.
The furnace is insulated with 2-1/2 of B7 refractory
firebrick as the primary insulation. This is backed up by 1 of very low K factor
mineral wool board on all surfaces except the bottom which has 2 of hard calcium
silicate back up for solid hearth support. This yields an excellent combination of
strength, insulating quality and fast heat up and cool down time.
The refractory sections are available completely shaped for easy replacement without
cementing. All sections fit together with engineered heat locks which improve the
insulating integrity of the furnace. No asbestos is used.
