Ox02c: Using simple time switches for cycling!

This new 2-column setup uses a silent oilfree compressor for pressurized air feed. We limited the number of required 3-way solenoid valves to two although we are using two filled zeolite columns. The valves are switched with a time switch, which can be programmed easily without any further technical knowledge.

Schematics

  • 1-2: 3-way solenoid valve
  • Zeolite bed: each ca. 250g LiX
  • Feed: 2 bar compressed air

Parameters&Performance

  • Column housing = Reverse Osmosis Membrane housing
  • 250g LiX in each column
  • Valves: Festo, Switching controller: Time switch
  • 70% oxygen in outlet stream (2.5 l/min) using pressurised ambient air (2 bar) in input.
  • Switching cycle :3s pressurizing A/blowdown B, 3s pressurizing B/blowdown A
