Green Composting Facility - Croydon For many years PHOENIX have been involved with various "green" projects. Mostly these projects have been involved with preventing pollution. "Green" waste composting plants are under consideration in many areas of the UK and in line with our plans to expand our activities in this area PHOENIX have recently completed the first stage ( six tunnels ) specifically designed for Green Waste Composting.
On this project PHOENIX won the contract to supply the whole electrical and controls package. Power was taken from a local transformer at 640 amps per phase. Cabling systems incorporated a mixture of SWA, Galvanised Conduit, Copper Braided CY, Screened Multicore and Jelly Filled Cables. Motor speeds are adjusted automatically using 12 X inverter drives on a multidrop Modbus link to the PLC. 49 temperature points are monitored and logged along with 6 X flows and 6 X Oxygen levels. Air intake, to control temperature and Oxygen, is achieved by 6 X modulating air dampers. All operator interfacing is via our Dlog package running on a desktop PC.
The contract consultants were Enviros, the civil contractors were Ascot Environmental and the M & E contractors were Hytech-Water. |
