Following the commissioning phase, Energy Partners ensures continuous performance monitoring and reporting of the system. This comprehensive approach encompasses performance metrics such as the efficiency, or Coefficient of Performance( COP), utilisation rates and system stability, all aimed at minimising the total lifecycle cost. Additionally, critical process parameters, including glycol and room temperatures, are systematically tracked, reported and analysed.
To further enhance operational reliability, Lactalis benefits from Energy Partners ' 24 / 7 remote plant monitoring service. This service promptly identifies, reports and addresses alarms and alerts, ensuring early detection and resolution of potential issues.
“ Working within existing structures presented unique challenges but was overcome by Morne de Kock, Lactalis project manager, being on site every day. His personal involvement in the removal of old equipment and the required diversion of electrical and water services proved invaluable. During the entire construction Morne was also on site daily and any unexpected problems could be resolved promptly,” commented Hougaard Langeveldt, head: Energy Partners Engineering. CLA
