RMG 901

The RMG 901 is a pneumatic gas pre-heater (vortex tube) with switch unit for the pilot of pilot-operated gas pressure regulators. The pre-heater can be easily integrated into the existing gas pressure control systems.​​​​

Features and Benefits:

  • 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 pmax: up to 100 bar
  • Max. temperature of housing Tmax: approx. 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.
