Understanding zone classifications, gas groups, and temperature classes for proper heater selection
Explosive gas atmosphere present continuously or for long periods
Explosive gas atmosphere likely to occur in normal operation occasionally
Explosive gas atmosphere not likely during normal operation; if it occurs, only briefly
High-temperature process heating
General industrial heating
Moderate-temperature applications
Low to moderate temperature
Low-temperature applications
Very low-temperature applications
Comprehensive certification and documentation to ensure regulatory compliance across global markets
Proper selection of explosion-proof electric heaters requires detailed analysis of the hazardous area classification, gas group, temperature class, and process conditions. Installation must comply with all applicable local, national, and international electrical codes and standards.
FATI by Thermon engineering review is mandatory FATI by Thermon engineering review is mandatory for all hazardous area heater applications. Our certified engineers will verify zone classification compatibility, review process parameters, confirm certification requirements, and ensure complete compliance documentation.
Installation, operation, and maintenance must be performed by qualified personnel in accordance with manufacturer instructions and local regulations. Modifications to certified equipment may void certifications and create safety hazards.
