Versatile generators for SMRs

Thanks to the versatility of our air- or hydrogen-cooled generators families, their configuration can be applied either for new steam power applications, synchronous condensers, or even for replacing an existing generator installed by Arabelle Solutions or other equipment manufacturers.

Flexibility to meet specific needs

Their compact sizes allow for easy worldwide delivery, installation, and maintenance. TOPACK, TOPAIR and TOPGAS generators offer a high factory pre-assembly levels enabling simplified installation, reducing erection times and allow for ease of maintenance.
