Semi-flexible solution for high air demand
Functional description and safety measures for the BR 55 breathing air station
The automatic changeover unit BR55 is designed for operation with breathing air cylinders or cylinder bundles with a maximum filling pressure of 300 bar. The system can be scaled up on request using input manifolds (Vareo distribution stations), so that several bottles or bundles can be connected at the same time.
High pressure is reduced in a first stage by main pressure reducers (left and right) to a line pressure of approximately 28 bar. A downstream working pressure reducer ensures that the required working pressure (between 0 and 10 bar) is supplied. The breathing air station is designed for a maximum capacity of 250 Nm³/h at 28 bar and is protected by a relief valve preventing overpressure in case of component failure.
Technical Data:
- Compliant with PED 97/23/EC Pressure Equipment Directive
- Robust housing provides standard mechanical protection
- Stainless steel base plate
- Shut-off valves: two on inlet side, one on outlet side
- Two preset main pressure reducers, each with high- and medium-pressure gauges
- Pressure reduction from 300 bar to approximately 25–35 bar (factory setting, typical nominal value ≈28 bar)
- Flow rate: 250 Nm³/h at 28 bar ( equals > 4,150 Nl/min)
- Automatic changeover unit
- Automatic switching at approximately 3–4 bar pressure difference
- Adjustable working pressure: 0–10 bar via downstream working pressure reducer
- Pressure relief valve
