Guangzhou Xingda printing machinery factory   

This machine is a kind of advanced energy saving and environmental protection type tunnel drying furnace our factory developed lately, specific features are as follows: using an AC contactor control general tunnel furnace control system, then stop heating when the temperature rises to the set temperature, when the temperature is lower than the set temperature at the time of a full power heating, so stop power supply to the interval of full power power supply time start repeatedly in 10 seconds, and the starting current to current was about 8 times larger than usual, unbalanced current directly led to the increasing power demand. The temperature difference is big, the time difference of 10 two degrees: tunnel oven control system produced by our factory adopts the most advanced technology of the electronic frequency,
