Heat Tracing Projects in Hazardous Areas
Heat Tracing Projects in Hazardous Areas with EHT Engineering
Safe, Durable and Smart Heat Monitoring Solutions
Process safety, energy efficiency, and operational continuity in industrial facilities become even more critical, especially in hazardous areas. In these areas, where explosive gases, flammable liquids, or systems operating at high temperatures are present, temperature control is not only a comfort factor but also a vital safety factor. At EHT Engineering, with nearly 30 years of experience, we design, implement, and commission electrical heat tracing systems—aka heat tracing projects—in hazardous areas (explosion-proof areas)2.
What is Heat Tracing?
Heat tracing is an electrical heating system that maintains pipelines, tanks, valves, and process equipment at a specific temperature. These systems are used primarily in outdoor installations to prevent freezing, reduce viscosity, increase fluidity, and ensure process continuity.
Heat tracing applications in hazardous areas must be designed and implemented in accordance with international safety standards such as ATEX and IECEx. With its specialized staff and certified products, EHT Engineering offers safe heat tracing solutions in high-risk environments.
Heat Tracing Application Areas in Hazardous Areas
EHT Engineering's Heat Tracing projects are successfully implemented in the following hazardous areas:
- Petrochemical plants
- Refineries
- Natural gas stations
- Chemical production and storage areas
- Power plants
- Mining enterprises
- Treatment plants
- Food and pharmaceutical production lines (Ex environments)
The electric heating cables used in these areas are selected to operate safely in environments with a risk of explosion, and their installation is carried out with special procedures.
