The purpose of this project is to design and produce the temperature controller of toluene tank used in laminate coating process, reduce solvent of glue and toluene loss for reducing raw material cost. The machine was transformed water cooler by decreasing temperature of solvent of glue and toluene that temperature can control from 17 – 23 °C by controlling thermostat.

Principle of the machine for reducing evaporation of solvent of glue and toluene is evacuation of heat from the solvent which it make the kinetic energy cause of evaporation down.

For testing the machine, the machine is tested in real...
