An explosive atmosphere is defined as a mixture of dangerous substances with air, under atmospheric conditions, in the form of gases, vapours, mist or dust in which, after ignition has occurred, an explosion could take place.
Our sealing systems are applicable to any wall or bulkhead penetrated by cables or pipes where the structure may be exposed to:
- Chemical plants
- Refineries and petrochemical plants
- Offshore platforms
- Paint shops
- Waste recycling plants
- Wood transformation workshops
- Food industry and flour mills
Different international regulations were created to avoid or minimize the risks of an explosion, like International IECEx directive, European ATEX Workplace Directive (Directive 99/92/ EC) or European ATEX Equipment Directive (Directive 94/9/EC), which implies all devices installed in a potential hazardous area.
These hazardous areas are classified according to the degree of risk of an explosion taking place, identifying if the risk comes from a flammable gas mixture or from dust.
In every company, the plant manager is responsible for evaluating the risks present at the site, and the implementation of the appropriate equipment in each zone identified.
Mines Paint shops Waste recycling plants Wood transformation workshops Food industry and flour mills Chemical plants Refineries and petrochemical plants Offshore platforms HTS combination of frames, blocks and accessories are certified according to ATEX and IECEx standards.
This includes rectangular and round marine and civil installations in standard HF version, but also guaranteeing EMI protection with HTS EMC Ex systems.
Hawke HF tolerant blocks are designed to accommodate cables/pipes passing through the frame.
Our special design incorporates five contact points which allows the blocks to accommodate a range of different diameters and accept variances in cable/pipe diameter. Each block that a sealing range of 3-4mm without the need for any onsite modifications.
Also, Hawke’s colour-coding system makes installation easier, faster and allows a visual inspection of the transit when complete, in order to guarantee safety in hazardous areas.
Hawke Transit System Ex products are design to be used as a cable penetration seal in Exe / Ex tb enclosures, motors, junction boxes, etc.
