  • Control-gas pre-heater (e.g., for pneumatic pilots)

  • Fully self-sufficient as preheating does not require any additional energy (Ranque-Hilsch effect)

  • Simple construction

  • Vortex tube without any moving interior parts

  • Easy integration into existing gas pressure control systems

  • Little tubing required

  • Optionally with pneumatic control unit

  • Only required in stations where zero gas consumption is possible

  • Suitable for non-aggressive gases, other gases on enquiry

  • SEP design according to PED

  • Max. admissible pressure PS: 100 bar

  • Max. operating pressure pmaxup to 100 bar

  • Max. temperature of housing Tmaxapprox. 60 °C at room temperature (approx. 20 °C)

    • Applicable within the range pu ≥ 2 · pd+ 5 where pu= inlet pressure in bar (over-pressure) and pd = outlet pressure in bar (over-pressure)

  • Connection: Pipe connections according to DIN EN ISO 8434-1 (DIN 2353), PN 100, for pipe sizes 10 mm and 12 mm

All mechanical components of this device are without potential ignition sources and/ or hot faces. They are not subject to ATEX 95 (94/9/EC). All electronic accessories, on the other hand, meet ATEX requirements.
