Paragon HT-22D Heat Treating Furnace
Machine shops save time with a furnace at their disposal in their own shop. You will no longer send a die out for heat treating, wait for its return and then send it out again for additional heat treating.
The door swings open with one-handed operation. A counter-weight handle holds the door securely closed. The door has a vent hole, so you can see inside the furnace during firing. Metal covers close the vent holes when not in use. (Always wear Paragon firing safety glasses when looking into a hot furnace.)
The furnace is insulated with refractory firebrick. The elements are mounted in dropped, recessed grooves machined into the firebrick. The groove protects the element for long life and low maintenance. When necessary you can thread new elements into place following clear instructions in the manual.
The firing chamber is protected by a steel case. The door is mounted with a heavy-duty hinge for smooth opening. A safety switch shuts off the power to the elements when the door is opened.
We use high temperature wire in the switch box for long life. A heat shield, mounted between the switch box and furnace, helps keep the switch box components cool even during extended operation. To further dissipate heat, the switch box is extra large and generously ventilated.
