The Aerated Static Pile Control System
Green Mountain Technologies has taken our in-vessel control technology and created a skid mounted aeration system for Aerated Static Piles(ASP) facilities. The skid comes with blower, dampers and control panel all mounted and ready to connect to aeration plenums and biofilter. The modular skid design minimizes site installation and engineering costs and installs quickly. The primary aeration control strategy utilizes a variable frequency drive to regulate blower speed to maintain constant duct pressure and minimize energy costs. Secondary aeration control is via zone dampers which regulates volume of air flow to each ASP zone. The system can operate in either positive or negative aeration modes by manually or automatically switching suction and pressure connections to the blower. 
The CompDACSCompost Data Aquisition & Control System The CompDACS™ takes the guess work out of composting. The computer based controller regulates the position of rotary dampers to regulate the direction and volume of process air. The CompDACS stores temperature graphs and prints reports to meet EPA 503 requirements for class A compost. |

Process air can be recirculated back to the piles or directed to a biofilter for odor control. The system includes a main control panel, field control panel(one for every 4 zones), and a J-box for each zone with a control damper and two temperature probes. All panel-to-panel communication is digital via Ethernet cable which minimizes field wiring requirements. Wireless temperature probes are available for sites where cables could interfere with operations.
