Glove box – GP CONCEPT-T4 (Jacomex, Dagneux)

Glove box with purification for manipulation of products sensitive to moisture and/or oxygen.

  • Attainable purity p(sys) purification: Below 1 ppm [O2], [H2O], that is 0.0001%
  • Vacuum antechamber: vacuum gauge -1/+1.5 bar, tighness: Leak rate < 10-5 mbar.l.s-1, vacuum pomp: 21 m3h-1 two stages with mist eliminator (vacuum at 10-2 mbar)
  • Pressure: overpressure or underpressure depending on user’s choice
  • Inlet gas: Electro valve controlled through PLC, outlet gas: system without backscattering through relief bubbler, independent from vacuum pump and electro valve controlled through PLC
  • Gas purification: Closed loop gas circulation – regenerable purifying loads
  • Purification unit: purification: H2O and/or O2 purification column, performance: H2O < 1 ppm – O2 < 1ppm, capacity: O2=30 l – H2O=1 440 g, purification flow: from 0 to 40 m3h-1 – (ΔP: 20 mbar) – Max. flow 110 m3h-1 (ΔP: 0 mbar)
  • Heating: Integrated temperature regulation controlled through PLC and temperature cut-out
