Polygap – Guaranteeing a long service life

Thanks to PolyGap®, MANGOLDT reactors are more reliable, higher-performing and have longer service lives than reactors built with conventional construction methods.

The patented distribution of individually sized air gaps within the core ensures consistent temperature dissipation and ensures a higher frequency stability as well as preventing stray magnetic fields outdoe of the reactor. PolyGap® also reduces power loss and sound emissions.
