Our Product Range
Explosion-Proof Transformers (Ex Proof)
Available in Ex d, Ex e, or dual-certified configurations, these transformers are purpose-built to prevent ignition in explosive atmospheres. Designed for Zone 1, Zone 2, and Class I Div. 1 & 2 areas, they ensure safe, efficient, and continuous power supply under the most demanding field conditions.
Flameproof Transformers (Ex d)
Engineered according to IEC 60079-1 (Ex d) standards, these transformers are designed to withstand internal explosions while safely containing the flames within their enclosures. Ideal for installations requiring blast containment and maximum enclosure integrity.
