The CompDACS is Green Mountain Technologies' state of the art computerized control system for compost process control and monitoring.
The primary aeration control strategy utilizes a VFD to regulate blower speed to maintain constant duct pressure. Secondary aeration control is stepper-motor damper which regulates volume of air flow to each composting zone. The system includes a main control panel, field control panel(s), and field J-boxes. All panel-to-panel communication is via Ethernet cable
The CompDACS continuously monitors and records the temperature of each composting zone, and successively implements up to four user-defined time/temperature process goals. PID closed loop logic is used to provide real-time control of damper positions and blower speeds.
This system receives commands and displays information through a graphical user interface (GUI) which runs on Windows™ based computers. The interface software graphs temperature data and prints reports to meet EPA 503 requirements for Class A compost.
