ABB has been manufacturing high quality electric motors andgenerators for more than 100 years. Motors for hazardous areasrepresent one of its special areas of focus. Working together

with major companies in the oil and gas, petrochemical andchemical industries, ABB has developed a comprehensive range

of products that offer safety, reliability and energy efficiency.

The regulatory situation where customers operate, is complexand constantly changing, with the latest developments includingthe new ATEX Directives. ABB not only ensures the relevantregulations but in many cases surpass them.

The worlds leading manufacturer of motors and generatorsfor hazardous areas

ABBs global reach provides significant benefits in todayslarge-scale projects. An oil company headquartered in Europe,for example, might construct a new refinery in South Americausing contractors and consultants based in North America.

With its significant project management experience,

ABB can rapidly assemble a team whose members interfaceon a local basis with the customer, consultants, contractors,OEMs, and other parties, helping to keep the projectrunning smoothly and efficiently.

Motors and generators for all protection categories ABB is a manufacturer offering a product range that covers all protection types.

ABBs motors and generators for hazardous areas comply with all relevant standards

European and IEC standards

Classification of hazardous locations According to European Directive 94/9/EC (ATEX),IEC 60079.10, EN 60079.10 and NEC 505,hazardous areas are differentiated according tohow frequently and over which period of timea hazardous concentration of an explosivemixture is present.

Gas symbol G Zone Criteria presence of gas

Category 1 Zone 0 Continuously or very long period

Category 2 Zone 1 Present in normal operation

Category 3 Zone 2 Unlikely but if present, only for a short time

( * ) In zone 0 no electrical motors can be installed.

Application groupsDepending on the intended use, explosion proof electrical operating equipment is divided into two major groups:

Group I Equipment for coal mines (only special designed motors for mines can be used)

Group II Electrical equipment for use other than mines (surface industry)Group II motors with flameproof enclosure are still further divided into gas groups: IIA, IIB, IIC.

High voltage motors comply with the local regulations in the US and Canada for Division and Zone areas.

July 2003 is the dead linefor the enforcement of keyEuropean directives:

Directive 94/9/EC (ATEX 100a) for all theproducts, electrical and non-electrical, to be installedin hazardous areas and defines the duties of themanufacturers Directive 1999/92/EC (ATEX 137) for the respectof the workers protection working in these hazardousareas and defines the duties of the end users.

NEC (National Electric Code) and CEC (Canadian Electric Code) nowadays have two systems for classifying hazardous areas.

The traditional division system and the new zone system, which refers to IEC standards.

Single source for allprotection types

When specifying motors or generators, the correct protectiontype has to be selected accordingto the operating and ambientconditions at the installation site.

With its extensive range of products for hazardous areas,

ABB is a manufacturer offeringproducts for all protection types.Major projects are easier tomanage if one manufacturer cansupply all the motors specified.

Exceeding officialrequirements

All motors for hazardous areassupplied by ABB are certified asmeeting official requirements, inmany cases exceeding the

requirements.

Full compliancewith standards

ABBs motors for hazardousareas are ATEX certified and mostof them show efficiency levelsequivalent to the highest Europeanstandard, EFF1. The high voltagemotors also comply with therequirements of National ElectricCode and Canadian Electric Codefor Division and Zone areas.

ABBs motors for hazardous areasalso comply with several nationalstandards like Russia, Australiaand China.

Certified for use with drives

Variable speed drives provide a number of advantages inmotor control, including better productivity, more accurateprocess control and energy saving. ABBs Ex motors aretested for safe use with drives, and ABB offers testeddrive & motor combinations.

From production to distribution, ABBs product range covers the entire processing chain

Support for end users

ABB supports its customersin their efforts to comply with official regulations. In addition toconcentrating on its own obligations

as a manufacturer as defined inthe ATEX 100a Directive (94/9/EC) it has also sought to ensurethat its products comply with the Worker Protection Directive,

ATEX 137 (1999/92/EC), which specifies the duties of the end user.

Custom features in standard products

ABBs motors and generators for hazardous areas have beendeveloped in close cooperation with customers in the oil, gas,petrochemical and chemical industries. All the products in therange are customized to provide enhanced reliability, safetyand energy economy as standard.

Effective logistics and rapid delivery

Low voltage motors up to 100 kW in most protection classescan generally be supplied direct from stock. ABBs central stocksystem helps to keep delivery times short. High voltage motorsare custom made to order.

Maintenance by authorizedlocal partners

Motors and generators must beregularly inspected and maintainedin accordance with themanufacturers instructions.In the case of the flameproof protection category, this work canonly be carried out by authorizedservice shops. Thanks to ABBs

worldwide organization and network of carefully selected partners,authorized servicing is availableon a local basis no matter wherethe customer is located.
