Optimized and Safe Power Solutions for Zone 2 Hazardous Areas
Increased Safety (Ex e) transformers are designed to prevent arcs, sparks, and excessive surface temperatures during normal operation, eliminating potential ignition sources.
This protection concept provides a reliable and efficient solution for Zone 2 environments.
ESTA Ex e transformers are engineered with controlled surface temperature, reinforced insulation systems, and certification-compliant design.
Protection Concept: Ex e
The Ex e principle:
- Prevents arcs and sparks
- Maintains surface temperature within T-class limits
- Incorporates reinforced insulation
- Minimizes risk of loose electrical connections
This approach ensures safe operation in hazardous areas where explosive atmospheres are not continuously present.
