A special adapter is now available that retrofits comprehensive communications capabilities to ensure customers can integrate existing Blue e cooling units into condition monitoring and IoT systems. It can be used to set up condition monitoring for up to 10 cooling units in a master/slave arrangement. That means, not only can data be recorded, but efficiency analyses can also be carried out on the cooling solution. A monitoring system that issues automatic notifications can also be set up to detect faults and limit breaches, thereby boosting availability and preventing expensive machine downtime. The new adapter is compatible with all NEMA 12, 3R/4, and 4X rated — both wall and roof-mounted — Blue e units that employ Rittal’s Comfort Controller. The NEMA 3R/4 or NEMA 4X classification, which are often used outdoors, are ideally suited for incorporation into IoT applications. Typical examples of outdoor applications for these units include renewable energy facilities, such as solar and wind power plants.
