 Heated Section

Nominal Operating Temperature:
Ambient to 900 degrees centigrade in the firing section.

Heating Method:
Type T-3 tubular quartz tube I-R lamps
located above and below the conveyor belt.

High temperature glazing is applied to all interior chamber surfaces
to ensure a clean, stable processing environment.Insulation: Multi-Layered, thermally optimized, graded,

insulation provides efficient thermal stability, cool external
panel surfaces and minimal heat loss.  Low mass refractory
materials are utilized throughout the heated chamber resulting
in rapid heat-up and cool-down times.
