In addition to the supply and repair of high frequency grinders and motors that operate at electrical supply frequencies over 50Hz, the RJW High Frequency department specialises in the supply and repair of new and reconditioned frequency converters (a rotary converter that allows high frequency machines to be run from a standard 3 phase supply).
Our experience together with extensive repair facilities has helped us to become the largest repairer of rotary frequency converters in the country. In order to support the maintenance requirements of the rotary converters, we are able to carry out overhauls and rewind units where required. During this process all frequency converters are load tested with a high frequency machine to ensure the correct output voltage and frequency.
All repairs are fully quoted with the cost and repair details and are carried out immediately following the acceptance of quotation and are typically completed within 3 to 5 days.
Quality assured to BS EN ISO 9001:2008, we are the only UK company that EME recommend as authorised repairers of their rotary converter equipment.
In addition to the repair service, we have a constantly changing stock of reconditioned frequency converters; these are available for sale for hire.
