A potentially explosive atmosphere exists when a mixture of air gases, vapours, mists or dusts combine in a way that can ignite under certain operating conditions. The source of ignition could be either electrical or mechanical in origin.
Promotech offers a range of intrinsically safe pneumatic drills that conform to ATEX II 2 G/D c IIC T6/T4 Standard for equipment used in hazardous environments. Explosive environments can potentially occur in many sections of manufacturing, processing and service industries, where the use of flammable gases, solvents and fine powders is involved.

Protection against accidental start up. Motor runs only when magnetic base is active.

Permanent magnets need no power supply from the mains.
Self-locking device prevents any possible accidental movement.

Base with permanent magnets can be adapted to a workpiece curvature.

Explosive or potentially explosive atmospheres may occur in many workplaces, where work activities create or release flammable gases, mists or vapours or combustible dusts. Working in such workplaces is hazardous because of the risk of fire and explosion that can cause loss of life, serious injuries, damage to property and the environment, and danger for business continuity. There are two widely used ways of reducing risk of accidental fire or explosion. Namely preventing releases of dangerous substances, which can create explosive atmospheres and preventing sources of ignition. Promotech ATEX drills are made of ATEX approved materials and feature combination of pneumatic drive and permanent magnetic base that eliminates the need of electric power supply, thus preventing possible source of ignition. Our drills are an ideal solution in many hazardous environments such as oil drilling platforms, petrochemical plants, oil refineries, shipbuilding and petrochemical industry, where electric appliances are prohibited for safety reasons.
