29 July 2011
WEG offers the oil & gas industry high levels of energy efficiency and protection in hazardous environments, with the launch of the W22X range of flameproof electric motors - shown for the first time in the UK at Offshore Europe 2011. ATEX/IECEx certified, they are IE2/IE3 energy efficiency rated and offer minimal noise, vibration, and low operating temperature for increased reliability and safety.
Available for low, medium or high voltage supplies, and with either Ex d or Ex d(e) flameproof protection, the W22X product range covers 2, 4, 6, and 8-pole motors in sizes up to 500 frame, across the power range from 160kW to 1,500kW. The first units released in the motor series are frame sizes 500KH: 4-pole, 6kV motors with power ratings up to 1,500kW.
The W22X range has CE marking in compliance with EU directive 94/4/EC - ATEX - and is classified as equipment Group I (mines) and Group 11 (surface industries), for gases Group llB and IIC. The range is suitable for use in Zone 1 - Gases and Vapours (G), and Zone 21 - Gases, Vapours and Dust (GO).
The advantage of dual certification for gas and dust is that it makes the W22X range modular and flexible, reducing inventory costs for users by enabling a common motor frame to be used with different types and sizes of terminal boxes.
The introduction of the W22X series complements WEG's existing range of hazardous areas products, which extends from 0.75kW to 40MW, and is available in Ex-P, Ex-N, Ex-e configurations, suitable for Groups IIA, IIB and IIC.
