ATEX heating requires equipment demonstrably suitable for the potentially explosive environment. An electric heater, a closed housing or a high IP rating does not by itself prove suitability.
Start with the hazardous area classification
Where flammable gases, vapours or dust are present, the employer must assess explosion risks and take appropriate measures. The area classification and conditions on site form the basis for selecting equipment. Have this assessment carried out by a suitably qualified expert.
Heating can be a potential ignition source. A solution is therefore selected within the explosion protection document and the overall technical and organisational measures.
Check the complete product documentation
For the exact model, ask for the relevant markings, conformity documents, permitted application, ambient temperatures and installation conditions. The equipment must suit the zone concerned, the gas or dust environment and the applicable temperature conditions.

Do not copy model data from a different version. Equipment assessed for a particular gas environment is not automatically suitable for every dust environment. A change in accessories or installation may also be relevant to the assessment.
An IP rating does not replace the ATEX assessment
An IP rating concerns protection against the ingress of solid objects and water. Explosion protection also requires specific properties and conditions. An IP66, IP65 or similar rating must therefore not be used as independent evidence of explosion protection.
Have the documentation checked against the actual installation and process. If information is incomplete, postpone the choice until suitability has been confirmed.
Installation, connection and maintenance form part of the assessment
Follow the manual for positioning, wiring, connection materials and clearances. Coordinate the work with the responsible specialist and record who will perform inspection and commissioning. General installation instructions for a home or office are insufficient here.
Periodic inspection and maintenance must also suit the risk and regulations. Do not regard the installation as maintenance-free because the heating element has no fan.
What information helps with an enquiry?
- The established zone and relevant parts of the risk assessment.
- The substances present and operating conditions.
- The required heating function and usage pattern.
- Available power supply, mounting locations and ambient temperature.
- The requested certificates and assessment documents.
