GROBET FIBER BURNOUT FURNACES-
are insulated with space-age ceramic fiber for fast heating and cooling at low
electrical cost. The firing chamber is 13" W x 13" D x 9" H (33 x 33 x 23 cm),
large enough for volume jewelry making. These kilns fire to 1700° F (967°C), so you can also use them for low-fire ceramics, enameling on metal, china
painting or glass fusing. A heavy steel case protects the firing chamber for
long life and the chamber is supported by a double-layer steel bottom. The base
lifts the furnace off the work surface so no stand is needed. You can watch the
firing chamber during heating through a peephole in the door. The peephole and
top vent-hole are sealed with: metal covers when not in use. The door remains
tightly sealed, even at high temperature, with the spring-loaded latch. Heats to
1,000° F (538° C) in 30 minutes.
The digital control models
use the DTC-800 controller, eliminating the need for a pyrometer. With this
feature packed temperature controller, you can program up to eight ramps
(raising or lowering the temperature at the rate you specify) and eight
dwells (holding the temperature constant for the length of time you
specify). The digital models use a type-K thermocouple, long proven for it's
reliability. The controller will shut off automatically should the
thermocouple fail and the controller stores up to six programs even if the
power shuts off. The furnace has a one year warranty. The controller has a
two year warranty. Can be shipped UPS. Shipping
weight 108 lbs. (49 kg).
MANUAL CONTROL GROBET FURNACES-
The manual control models use an infinite control switch with pilot light. A
pyrometer hole is drilled in the back of the firing chamber. (Pyrometer not
included, sold below). The furnace comes with a one-year warranty. A digital
controller may be purchased separately to be used in place of the pyrometer.
Can be shipped UPS. Shipping weight 108 lbs. (49 kg).
