Ex motor certification cuts costs

12 August 2008

ABB motors has achieved certification for its non-sparking (Ex nA) and increased safety (Ex e) motors, which meet the latest IEC and EN standards according to IEC 60079-15:2005 and EN 60079-15:2005 for Ex nA and IEC 60079-7:2006 and EN 60079-7:2007 for Ex e.

ABB claims that achieving certification for motors ensures reduced initial capital expenditure, lower operating costs and faster starting. This is because uncertified motors need special measures such as pre-start ventilation, which requires a higher capacity air compressor, piping and a ventilation control unit, increasing capital expenditure. Uncertified motors also require purging every time the motor is started, increasing the time taken to get plant up and running.

Reliability is also improved as no additional components are required, says ABB. Most importantly, certified motors offer proven safety, as testing represents the only way to verify that equipment is really safe.
