ATEX protection for mechanical equipment. ATEX mechanical protection is based on the risks and variability of a situation where equipment must be safe in normal as well abnormal work conditions. Mechanical protection concepts are defined in multi-part EN13463 standard; please see below for more information. ATEX directive allows manufactures to introduce innovation in products.

The figure below provides a schematic overview of the ATEX Directives and their correlation. SCOPE OF THE ATEX GUIDE This document is a simple guide to the ATEX Directives, their Explosion protection in Europe ATEX Directives ATEX Directives define the free trade of goods within Europe.

One control platform | Safety, explosion protection and measurement series: Control Panels and Panel PCs for multi-touch operating concepts in Zone 2/22.

Ex i Intrinsic Safety is an explosion protection concept in which the electrical energy within the equipment is restricted to a level which is below that what may cause an ignition or to limit the heating of the surface of the hazardous area equipment. ATEX 137 (operator guideline) defines the operator's responsibility The explosion protection guideline 1999/92/EC (generally known as ATEX 137) contains basic safety requirements concerning hazards from "explosive atmospheres".

ATEX is the regulatory directive for the design, installation and use of products in environments where there is a potential explosion risk from flammable gases or dust that are or could be present in the surrounding air. For more in-depth information on the ATEX directive we suggest you visit the UK Health and Safety Explosion protection safety concept for use in mechanical vacuum pump systems in secondary metallurgy steel degassing processes TodayÕs international standards for mechanical vacuum systems are based on the latest generation Roots-type vacuum pumps and dry screw-type vacuum pumps. Degassers, particularly ATEX Explosionsschutz GmbH has started offering a remote assistance solution through which we will be able to help our customers worldwide. In the development of holistic explosion protection concepts the consideration of explosion decoupling is indispensable.

In the development of holistic explosion protection concepts the consideration of explosion decoupling is indispensable. TYPE OF PROTECTION “FLAMEPROOF” Ex d – IEC 60079-1 The concept is simple: put the electrical equipment to be protected in a strong enclosure that is capable of withstanding an internal explosion without bursting or without allowing the escaping hot gasses to ignite an external explosive atmosphere.

Where equipment is rated for use in more than one ATEX Group, there will be an Explosion Classification for each. Protection Concepts: 0: In which an explosive gas/air mixture is continuously present for long periods: Exia or Exs: 1: In which an explosive gas/air mixture is likely to occur in normal operation.
