Ex p Solution for Label Printer
Installed inside an Ex p stainless steel enclosure, standard label printers can be used directly in hazardous areas. Already printed labels are extracted from the printer by means of an additional door in the front of the enclosure.
Description
The printer doesn’t need to be switched off during this procedure. A window in the frontdoor and the additional lamp installed inside make it easy to read the printed labels. The enclosure also has a door on the side. The printer is installed on a sliding system, which makes it easy to carry out inspections and to apply new labels.
The Ex p systems works thanks to an overpressure inside the enclosure compared to the surrounding pressure.
After a pre-cleaning phase, in which, if possible, existing gases are expelled, the controller switches on the installed internal devices.
