Product Description

By integrating PID control with SCR technology, precise temperature control with comprehensive safety protection.
50-Segment Temperature Control Program Settings:1 curve = 50 segments;2 curves = 28 segments/curve; 3 curves = 15 segments/curve; 5 curves = 9 segments/curve.

Furnace Lining is constructed from vacuum-formed high-purity alumina lightweight material (reinforced with alumina hollow ball boards at impact zones—mouth/base) for extreme heat resistance, minimal heat storage, and thermal shock durability (no cracking/spalling).
Dual shell ventilated housing made of carbon steel for low surface temperature(<45℃) and high stability
Safety Feature: Main heating circuit disconnects automatically when the door opens at high temperatures.
