The CompDACS™

Compost Data Acquisition and Control System

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 via a 3-position damper which regulates volume of air flow and direction of air flow to each composting container. 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 compost batch, 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.
