Abstract:
1. A system for maintaining optimal humidity and temperature in a clear coat paint booth, comprising: an air supply unit providing forced air to the paint booth, the air supply unit having a pre-heat burner, said pre-heat burner positioned to heat air entering the air supply unit; a temperature PID controller in electrical communication with said pre-heat burner, said temperature PID controller pre-programmed to make adjustments to the pre-heat burner to track an input temperature set point; a temperature sensor in electrical communication with said temperature PID controller, said temperature sensor monitoring the temperature in said paint booth; a humidity sensor monitoring the humidity in said paint booth; and a humidity PID controller in electrical communication with said humidity sensor and said temperature PID controller; wherein, when the monitored humidity within said paint booth falls outside of an optimal window, the humidity PID controller is programmed to transmit an adjusted temperature set point to said temperature PID controller, which will override an existing temperature set point and cause said temperature PID controller to operate said pre-heat burner in a manner that moves the humidity level within said paint booth into said optimal window.
