E-2000 Evaporator

The Wallace & Tiernan® Systems E-2000 Evaporator is a water-immersed tank heat exchanger specifically designed for the conversion of liquid chlorine to a gaseous state.

​The latent heat of evaporisation limits chlorine gas withdrawal from containers. An evaporator is necessary wherever the large quantities of gas are required and the rate of gas withdrawal from multiple containers is not fast enough to keep with this requirements. The E-2000 Evaporator can also be adapted for handling other gases such as sulphur dioxide.



  • ​Disinfection in large municipal or industrial water plants
  • Chlorination of municipal sewage
  • Disinfection of municipal and industrial wastewater
  • Bleaching and waste treatment in pulp and paper mills
  • Aluminum fluxing (removal of magnesium)
  • Treatment of cooling water in power plant

 Technical Data

  • Standard capacities: 200 kg Cl2/h; 100 kg SO2/h
  • Power consumption: approximate 18 kW  

 Key Benefits

  • ​Handles chlorine and sulphur dioxide
  • Water temperature thermostatically controlled
  • Electrical interlock of all safety arrangements
  • Automatic pressure reducing and shut-off valve protects gas feeder from liquid entry
  • Both gas chamber and water-bath tank are cathodically protected by three magnesium anodes against corrosion from the hot water
  • Reduction in the number of containers employed
  • Footprint reduction E-2000 Evaporator
