IHC has been in the anodizing business for almost 40 years and during this time we have had the opportunity to use and evaluate many vendors.  Of the many vendors that we have evaluated over the years, Dynapower has proven itself as one of the best.

Although we had low output Dynapower rectifiers for sulfuric and chromic anodize since our founding in 1962, we purchased our first Dynapower hard anodize rectifier in approximately 1970.  This unit had 2000 amp, 75 volt output.  Although it is hard to believe today, that rectifier was one of the very early models using solid-state controls for high output applications.  This rectifier ran well when we bought it and, in fact, still continues to run well today after 30+ years of intensive use.

Throughout our history we have continued to acquire Dynapower rectifiers.  Today we have an approximate total of 20 units ranging in output from 200 to 10,000 amps.

Over the years we have found Dynapower to build very robust units that rarely require service other than routine maintenance.  In the few occasions that we have required service help, Dynapower has provided high quality technicians and made repairs in a timely manner.  Even though the vast majority of our power supplies are from Dynapower, the majority our Dynapower service calls have been to repair the few machines we have that were built by other manufacturers.

As our need for larger and more sophisticated equipment continues to increase, we will continue to look towards Dynapower as the supplier of choice.

Sincerely,
