6,Cooling system:

Cooling structure	stainless steel water jacket.
Cooling mode	Use gas cooling plus water cooling
Cooling detective	One water temperature thermocouple in the cooling water jacket
Alarm instructions	Low water pressure and over temperature alarm.

7,Safety protection

stop button.	One stop button is set at each end plate of the inlet and outlet. After pressing the button, the belt stops running
Alarm indication	Over temperature, temperature deviation, frequency converter, thermocouple broken, low water pressure, low gas pressure,Igniter failure sound and light alarm
Heating up Rate	≤2ºC/min
Power off protection	Installation of manual shaking out device

8,Temperature control system:

Temperature measurement	Each control and detection point is measured independently by K/S type thermocouple
Control instrument	Use of intelligent temperature controller to control, with PID parameter auto tuning, high temperature upper limit alarm, thermocouple failure and other protective alarm functions.
Heating control	The heating part is supplied by several AC contactors in groups to reduce the instantaneous current impact of the equipment on the power grid.
Control mode	Solid-state relay zero crossing triggering mode
Over temperature Alarm	When over temperature occurred in some zones, over temperature alarm system in corresponding zones immediately send audible and visual alarm signal and meanwhile the heating of this zone is cut off, the buzzer sounds alarm
Computer Control System	DCS (distributed control system) control system is adopted
	Lower single loop intelligent instrument control, upper industrial control computer monitoring
	Friendly man-machine interface, multiple program storage, convenient for users to edit and call
	Real-time temperature and alarm record, data saving and printing.
	The computer control system has the function of slope heating, which effectively prolongs the service life of muffle tube.
	It also can provide the temperature calibration function in the chamber for adjusting process requirement.
