SAANA –liquid cooled dUdT filter
Saana is the newest member of our liquid cooled dUdT filter family. Integrated liquid cooling concept enables the compact size of the filter. In addition, loss transfer ratio to liquid is more than 95%, which reduces filter surface temperatures and hence the air temperature in the cabinet. Typical applications for Saana are e.g. wind turbines and motor drives.
