Description
Safety features
- Furnace overheat protection cuts off power when temperature is over the desired range.
- Thermocouple protection cuts off power when the thermocouple is broken or malfunctioned.
- Temperature variation protection cuts off power when the difference between actual temperature and target temperature is off the desired range. (refer to controller’s manual)
- Power failure protection resume furnace operation right after the point of failure when power is back up.
- Stainless steel flange support makes sure the tube and flanges are secure and in their absolute position, it also longer the life of the tube.
Warning! NEVER fill furnace with explosive gases, including Hydrogen, Carbon Monoxide and Methane.
