Baldor Electric Company, represented by Baldor Australia , have introduced a new line of motors certified to the International Electrotechnical Commission (IEC) standards within the IECEx certified equipment scheme. The certification allows Baldor Electric Company to meet customer needs in the international market with motors that are designed and suitable for hazardous or explosive atmospheres.
Baldor Electric Company offer the Ex dI/IIB Gb T motors for explosive gas atmospheres, and the Ex tb IIIC T Db IP6X motor for explosive dust atmospheres, where T represents various temperature codes. These motors cover the NEMA frame ranges of 180 to 449T and IEC 112S to 280H, and are similar to Baldor Electric Company’s Class I and Class II Division 1 offering.
To achieve the IECEx certification, Baldor Electric Company designed the motors to comply with the IEC standards, and submitted the products for testing by an accredited IECEx test laboratory. The products also had to undergo an independent review for certification by an IECEx certification body, and Baldor Electric Company was required to maintain a quality record on each motor shipped. The objective of the IECEx system is to facilitate international trade in equipment for use in explosive atmospheres, while maintaining the required level of safety.
Hazardous areas and explosive atmospheres relate to areas where flammable liquids, vapours, gases or combustible dusts are likely to occur in quantities and cause a fire or explosion. Industries that utilise these motors include oil refineries, chemical processing plants, underground coalmines, grain handling, and sugar refineries.
The IECEx certified equipment scheme presently operates in 31 countries that have agreed to accept accredited equipment certifications to IEC standards. These motors also carry ATEX certification for the European Union.
