Applications
-
Oil & Gas Processing Plants
In hazardous gas environments such as refineries, LNG facilities, or offshore platforms, the emergency stop station provides operators with a quick shutdown control for pumps, compressors, or conveyors. In the event of a gas leak or fire risk, pressing the Ex-rated mushroom button immediately cuts power to critical equipment, preventing escalation and ensuring worker safety.
-
Chemical & Pharmaceutical Manufacturing
Chemical mixing and pharmaceutical production often involve flammable vapors and dusts. The Ex emergency stop station allows workers to halt machinery and batch processes instantly during unsafe conditions, such as a spill, overheating, or dust ignition risk. Its IP66 enclosure ensures reliable operation even in areas with chemical exposure, high humidity, or washdowns.
-
Mining
In underground mines or grain silos where combustible dust is present, the emergency stop station serves as a critical safety device for conveyors, crushers, or ventilation systems. Positioned along work areas, operators can activate the stop function to prevent accidents, equipment jams, or dust explosions, even under extreme temperature and environmental conditions.

Why Ex-certified Emergency Stops Are Critical
In Zone 1, Zone 2 (Gas) and Zone 21, Zone 22 (Dust) areas, standard electrical equipment can pose a serious ignition risk. Ex-certified emergency stop stations are specially designed and tested to:
- Contain or prevent explosions caused by electrical sparks.
- Withstand harsh environments such as offshore platforms, refineries, chemical plants, and mining sites.
- Maintain safety in extreme conditions, with protection ratings such as IP66 against dust and water ingress.
