Mechanical automatic volume flow rate controllers for constant volume flow systems, circular, approved and certified for ATEX, for explosion preotected aereas
The system-powered constant volume flow rate controllers type RN in explosion-proof construction are ATEX-approved for use in supply and exhaust air ventilation systems in potentially explosive atmospheres.
To simplify applications in individual projects, the controllers can be ordered and installed according to the required size. The desired value is then set simply and reliably when installing the controller.
The RN-Ex controllers are certified for explosion protection group II for zones 1, 2 & 21, 22. Zones 1 and 2 apply to situations with gases, while zones 21 and 22 apply to situations with dusts. The zones are classified by the operator or designer in compliance with applicable standards.
