Safe Low-Power Supply Solutions for Hazardous Environments
ATEX control and isolation transformers are designed to supply safe power to control circuits, instrumentation systems, and low-power auxiliary equipment operating in explosive gas or dust environments.
These transformers provide secure energy supply through ignition risk minimization and controlled surface temperature design.
ESTA ATEX control and isolation transformers can be engineered for Zone 1, Zone 2, Zone 21, and Zone 22 applications.
Protection Concept
ATEX Cast Resin solutions are typically applied under:
- Ex e (Increased Safety)
- Ex ec
- Zone 2 / Zone 22
The oil-free design minimizes environmental and operational risks.
