This project, designed for an underground gold mine in Congo, involved the designing and manufacturing of four modular fan power supply rooms.

The dimensions of these rooms were 11.5 x 2.4 x 3.8 m and they included a 1250 kVA power transformer with double secondary windings, medium voltage switchgear, medium voltage variator, duplicate air-conditioning system, auxiliary services, fire detection and suppression panels, as well as the fan control system. The intention was to provide the maximum ventilation reliability required in this underground mine.

Since the buildings were installed, they have been in operation 24 hours a day, 365 days a year.

Another major feature of the project is that the room was designed for equatorial climate conditions. A lightning protection system was also installed during the construction work.

To ensure significant savings during on-site assembly, the solution was tried and tested at the factory. However, our technicians travelled to Congo to provide technical assistance for assembly and commissioning tasks during the various stages of the project.
