ABB motors for explosive atmospheres come in three certified families, all carrying ATEX and IECEx approval. Flameproof Ex db covers 0.18 to 950 kW. Increased safety Ex ec and Ex eb covers 0.12 to 1,000 kW up to IE4, for Zone 1 and Zone 2. Dust ignition proof Ex t covers 0.12 to 1,000 kW up to IE5, for Zone 21 and Zone 22.
Abtaz supplies ABB motors for explosive atmospheres for pumps, fans, compressors and agitators. Typical sites are refineries, petrochemical plants, offshore installations and chemical processing. Send us the zone, the gas or dust group and the duty data. We will confirm a protection type and frame size.
0.18 to 950 kW at 230 to 690 V, in frame sizes up to 450.
The flameproof branch contains an ignition inside a robust enclosure so it cannot reach the surrounding atmosphere. ATEX and IECEx certified, it is the usual choice for Zone 1 gas areas in refineries and petrochemical plant.
0.12 to 1,000 kW at 230 to 690 V, up to efficiency class IE4.
Increased safety construction prevents arcs, sparks and excessive temperatures arising in the first place. ABB covers Zone 1 with Ex eb and Zone 2 with Ex ec, and was first to bring a magnet-free IE6 SynRM increased safety motor to hazardous areas.
0.12 to 1,000 kW at 230 to 690 V, up to IE5, frame sizes to 450.
Ex t motors are certified for Zone 21 and Zone 22 with conductive or non-conductive dust, where the risk is a dust layer or cloud rather than gas. Typical duties are grain handling, milling, sugar and chemical powder processing.
Cast iron IEC low voltage induction motors up to 355 kW, in efficiency classes IE2 to IE4, for pumps, fans and compressors in general industrial duty.
IEC low voltage motors from 0.12 to 1,300 kW, configured to the installation and available up to efficiency class IE5, for demanding process plant.
Magnet-free IE5 and IE6 synchronous reluctance motors from 0.75 to 450 kW, driven by an ABB inverter, for pumps, fans and compressors.
Rib cooled and modular high voltage induction motors up to 28.5 MW and 13.8 kV, for mills, large pumps, fans and compressors.
IE5 variable speed motors from 1.5 to 30 kW with the drive module built onto the motor, removing the need for a drive cabinet.
