AIA: Seals Create Safe Environment for Electronics
Daisy Data Inc. (New Haven, PA) specializes in manufacturing electronics equipment enclosures and purging controls for use in hazardous areas like those found in the food processing and pharmaceutical manufacturing industries.
The basic function of the enclosures is to keep electronics that have the potential of producing sparks or high temperatures isolated from explosive environments. This is done by placing the equipment-often a computer or monitor-in a sealed stainless steel enclosure. The enclosure is then protected by a microprocessor-controlled purge system that replaces the enclosure atmosphere with inert gas under slight pressure. The enclosure system includes viewing windows, internal fans and alarm contacts.
