Electric heating systems for use in hazardous areas are often individually planned and installed on the basis of specific customer requirements. While engineering the Ex-solution, it is crucial to carefully examine all relevant Ex aspects at an early stage.
The specifications in the context of explosion protection must be carefully coordinated with the customer, i.e. the Ex-parameters, e.g. zone classification/equipment categories as well as Ex parameters for flammable substances (gases, vapours and dusts).
The engineering, installation and initial testing of the electrical Ex equipment and systems should be implemented professionally. For this mix of tasks, planners and electricians can find comprehensive information in DIN EN IEC 60079-14 for the selection and installation of electrical devices in Ex areas.
For electrical Ex devices, their marking provides all the essential information.
For this purpose, we offer you a practical overview of Ex marking as a PDF (see link below).
