Ex p Printer, for print jobs directly in the Ex-Area, customer- and application- specific stainless steel housings .

Properities

These customized industrial printer solutions are conceived for the direct employment in the Ex Zones 1 and 21.
In combination with the protection class "pressurized enclo-sure" (Ex p), stainless steel housings are applied, which are suitable for the use in raw industrial field.
The complete application features an ATEX compliant ap-proval, based on the EC- type certificate DMT 02 ATEX E 086. This achieves a realization of your Ex-printer project at optimal time and cost.
Using label printer applications, a direct paper withdrawal in the hazardous area is possible. The paper emission is real-ized by an adjustable slot in the Ex-p housing.
This causes the specific difficulty of excursive changes of the housing leakage at the slot as a result of the change of paper thickness at the initial and end point of each label (see figure left).
The patented control unit FS850S achieves, in connection with the SVP proportional valve at the inlet, a minimum purg-ing gas consumption in combination with highest working reliability.
With the FS850S, creeping leakage rates, caused e.g. by aging of the housing seals or cable glands do not lead to early failures as at conventional Ex-p systems.
The concept offers highest realization flexibility: most diverse printer models, interfaces as well as windows and control elements e.g. buttons for line feed or print abort can be in-serted. Also mobile solutions are realizable!
