AX-4-10B
Burnout Furnace
(Intelligent)

Description:
The AX-4-10B Intelligent Burnout Furnace is used in dental labs, it is updated
from manual burnout furnaces. This burnout furnace is designed for dental
technicians for heating precious dental alloys. It can show the temperature inside
the chamber (temperature increase, temperature keeping time) and the selected
temperature increase rate, temperatures at different stages, and temperature
keeping time. The LED displays the precise temperature and time of each program
in a user-friendly way. It has four-stage preset heating programs, the heating
process is finished automatically and no need to be guarded by users. When a
program is finished or there is any problem it will alert the users by alarm. The
temperature increases and temperature keeping process is done automatically, and
the temperature and time control is very accurate. The time relay function enables
the machine to started after 1-96 hours (4 days). There is a ventilation fan and an
automatic power supply. This furnace is easy to use and clean.
