Horizontal Sealing Device
Temperature Controllers
The temperature controllers monitor and adjust the horizontal sealing
temperatures. There is one controller for each jaw assembly. The
controller applies full voltage to the heating cartridges until the set
sealing temperature is reached. Then, it cuts the power to the
cartridges. While the temperature controller is on, it continually turns
the power to the heating cartridges on and off to maintain the set
temperature.
