Find high quality small two zone tube furnace with competitive price here. Please rest assured to buy small two zone tube furnace with Shanghai HaoYue Furnace Technology Co.,Ltd

The tube furnace uses high quality resistance wire as the heating element with double shell structure, the 30 programmable segments temperature control system and phase shifting triggering thyristor control. The chamber uses high purity alumina crystal fiber material and it is divided into two semicircle. Hearth will be opened when it needs rapid cooling or pipe changing. Double furnace shell air is equipped with cooling system, for rapid temperature rising and dropping. The furnace has these advantages: uniform heating filed, low surface temperature, rapid temperature rise/drop rate, energy saving and so on.

The tube furnace adopts advanced international technology, including single tube, multi tube, horizontal, open type, vertical, single temperature zone, double temperature zone, three temperature zone and so on. It is mainly used in the experiments of colleges and universities, industrial and mining enterprises and small batch productions. The utility model has these advantages: safety and reliability, simple operation, high temperature control accuracy, good heat preservation effect, wide temperature range, high uniformity of furnace temperature, multiple temperature zones, optional air distribution, vacuum furnace type and so on.

Temperature Control System:

  Using PID automatic control and auto-tune function and 30 programmable segments for heating and cooling, K-type thermocouple for temperature measure and built in protection for the over-heating and broken thermocouple. with the temperature control accuracy ±1?.
