Produced in Maia Portugal, WEG’s Centre of Excellence for the manufacture and design of MV and HV explosion proof induction motors, the W22X is a global range that meets worldwide standards. It is certified to ATEX and IECEx, including Ex d(e) I Mb, Ex d(e) IIB T4 Gb, Ex d(e) IIC T4 Gb and Ex tb IIC T125ºC Db IP6X designations, so is deployable in most hazardous area environments. Other national and regional certifications, such as GOST, CCOE, INMETRO, will be available in the future.
The design of the junction box has been rethought so that it includes internal mounting bolts for protection against impact and environmental damage and prevents the accumulation of water whilst providing generous space for easy connections. There are multiple options available for the junction box while a current transformer, surge arrestor or capacitors can be fitted to the W22X.
The three new frame sizes are all available in 2, 4, 6 and 8 pole versions with medium and high voltage options and a range of maximum outputs from 500kW to 4500kW. The whole W22X range is based on a welded steel construction and includes integral solid feet so that vibration is kept to an absolute minimum, complementing the low noise outputs.
With the W22X range WEG has the capability to provide optimal explosion-protected solutions for virtually all situations, from gas pipelines in the Arctic to oil rigs on the hottest spots of the Arabian desert (From -55ºC up to +60ºC), offering unmatched reliability, world-class certification, reduced costs of operation and assured safety.
