GEA Air Treatment GmbH offers the Fricostar energy monitoring system. The system is based off the M bus (meter bus) and enables values from meters for heat, electrical power and water to be read into a higher-level process-control system, for example. Fricostar's control system displays consumption data for fans and compressors.These monitoring features allow display or read-off of current power consumption, cumulated consumption values, specific fan power values or heat-recuperation data. In addition, bar diagrams give the operator the possibility to monitor plots for a week to optimization system operation on the basis of data on operational time, temperatures, etc.
