Each NAR rectifier is custom made to your specifications for your application. NAR is the leader in convection and air cooled rectifiers which eliminates the cost and maintenance associated with cooling water systems. A proven track record of over 40 years of air cooled operational success is primarily attributed to robust internals that even when an NAR rectifier is at full output, the internals are operating well below their design ratings hence generating less heat. Generously sized and numerous heat sinks further assist in dissipating heat. It is common for NAR rectifiers to operate in 45C conditions under continuous duty without any overheating interruptions.
