LAUDA-KOENIGSHOFEN, Germany - April 27, 2021 - PRLog -- For toluol supply facilities in zone 1, the customer required a system with a zone 2 panel by Siemens. In addition, the costumer required that the touch function of the twelve inch widescreen TFT display be completely retained even under harsh industrial conditions.
For the customer, the Quintex Overpressure System was the most flexible and efficient.
the overpressure control by Quintex was the solution with the most flexible options.The advantages were obvious:
  • a high degree of flexibility and design freedom
  • easy installation and maintenance
  • overall, more cost efficient and technically efficient than other solutions
  • therefore, a standard panel by Siemens could be used
The Quintex solution:
With the system, by automatic clearance measurement inside the enclosure with an approved, stationary gas detector, the non-existence of an Ex area can be verified and, with the overpressure during operation, a non Ex area can be retained.
Only when no flammable gas is detected in the enclosure and, in addition, the pressure inside the enclosure, as specified in the Ex standard DIN EN 60079-2, is maintained, the following electrical components will be switched on.
this is fully automatic without the customer having to carry out any operation.
within 2 minutes, the system is ready for operation, irrespective of the size of the enclosure.

With its special solution, Quintex allows for the zone 2 panel to be operated with complete functionality of a touch screen in zone 1.
The touch screen is implemented with a special foil, which is flushed with compressed air.
To save space, all the components are premounted on plates inside the enclosure by Quintex.
thus, expensive final inspections can be avoided.
The implementation is proven by practical experience.
the customer is enabled to assemble the mounting plate, to set up electrical wiring and to install the plate in the cabinet later on.
The mounting plate is delivered with all the required overpressure components, proven in accordance with the Ex criteria, by Quintex.
The system can be easily and rapidly switched on again.
the system is approved in accordance with ATEX and IECEx.
This solution is tested and certified by two independent certification bodies.
Thus, safe usage is guaranteed in zone 1 and 21 as well as in zone 2 and 22.
In principle, however, there is also the option to merely buy the electronic components required for monitoring the non-Ex area by Quintex and to use your own cabinet.
