Applications

  • Small lab evaluations of electrochemical processes when
    minimal flows and chemical use are requirements
  • Process studies with expensive chemicals
  • Screening tests on different chemicals, electrodes and membranes
  • Evaluation of different fuel cell- and redox concepts

Features

  • Possibility of 4 different electrolyte flows
  • Leak-proof construction
  • Gas diffusion electrodes can be installed
  • Set of electrodes (Pb, Ni and DSA-CI2) supplied in addition to the cell electrodes (SS and DSA-O2 pH<2)
  • Designed to allow for internal heating / cooling
  • Small internal cell volume
  • Turbulent promoter for improves mass transfer
  • Full laboratory package available with cell as option 

From lab, pilot to production – Electro Cell is the “One-Stop-Shopping-Place”

Expertly designed and engineered flow cells are available for applications including chloralkali and synthesis of a wide range of inorganic and organic chemicals. These modular membrane cells have found application world-wide! Start with a laboratory unit as small as 0.01 m2 (Electro MP Cell) or 0.04 m2 (ElectroSynCell) and expand to a pilot scale module, and then to the production plant size by adding on modules, or installing the Electro Prod Cell, especially designed for production. Injection moulded cell parts are available in a wide range of inert materials. Electrodes can be of DSA®, Pt on Ti, PbO2 on Ti, graphite and many others. Further advantages; leakproof, uniform hydrodynamics and current distribution, and narrow inter-electrode gap.
