Units for areas with potentially explosive atmospheres (ex zone)

For many years, HAUG has been a competent manufacturer of ionizing units approved for equipment in areas with potentially explosive atmospheres. These are intended to eliminate unwanted electrostatic charges in areas where hazardous gases may form, such as paint plants or printing machines.

• Graphical industry: Screen, tampon and offset printing machines etc.
• Paint shops: Automotive paint applications, painting of plastic parts, etc.

The design of the ionizing bar EI Ex T complies with the International ATEX directivities. In combination with the power pack EN 92 Ex or Multistat Ex, it is suitable for use in manufacturing locations with potentially explosive atmospheres resulting from gases of explosion group IIA, temperature classes T4 to T6.

By installing the ionizing bar in a suitable body, a compressed-air assisted ionization system can be created. This air blade is particularly suitable for blowing-off processes on plate and web material or where installation is difficult, e.g. in the case of distances further away from the material.

The Multistat Ex is a modern high-voltage power pack with fully electronic watchdog function. It is fitted with an automatic fault alarm, an analog display for high-voltage monitoring and an output jack for the connection of peripheral alarm units.

This power pack must always be installed outside the potentially explosive atmosphere. It is approved for the operation of ionizing bar EI Ex T.

Explosion Proof Static Bars, Explosion Proof Power SuppliesPower pack EN 92 Ex is suitable for direct use in areas with potentially explosive atmospheres (zones 1 or 2).

The units comply with the ATEX directives. All high-voltage components are accommodated in a flameproof housing. The power pack EN 92 Ex is equipped with two high-voltage ports for the connection of the ionizing units. No long high-voltage cables are required, as the power pack can be installed in the immediate vicinity of the ionizing unit.

The power pack EN 92 Ex has been approved for operating the ionizing bar EI Ex T.
