Degassing Towers

A standard range of Carbon Dioxide degassing systems designed to reduce dissolved CO2 economically with proven technology.

Degassing Towers

The CO2 Degassing Process

Forbes Degasser Towers operate on the principal of passing the water to be treated over a large surface area whilst blowing air against the flow. The resultant mass transfer of gas at the interface of the water and air removes the acid forming carbon dioxide.

design life of 20 years is achieved using high quality plastics throughout the construction. Provided that water and air supplies are free from solid impurities, Forbes’ degassing systems normally require no maintenance other than regular external inspection. Where practical, fans are sited at low level for ease of inspection and access to filters, if fitted.

Years of trouble free performance in the field have proven the essential reliability of Forbes Degassers.

  • Corrosion free construction
  • Simplicity of installation and setting up
  • Dependable automatic controls all contribute to long trouble free performance

Standard FD Models

Performance - With the standard controls the minimum water pressure at the inlet flange is 0.5 bars g and the maximum is 5 bars g. The unit comprises a packed tower with base mounted fan and integral sump. Sump retention time is approximately 2 minutes at maximum flow rate.

Controls -  Control od the inlet water flow is by a float-operated ball valve, sensing the sump level. A float switch within the sump controls output pumping, protecting pump equipment from dry running.

Standard Features - Corrosion-free high quality all plastic centrifugal fan, inlet, outlet and overflow connections. Inlet valve and pipework to tower top. Tower cowl, sump access hatch and a sump level switch with approximately 5M fly lead.

Non-standard Models

Non-standard designs are also available for water flows up to 1000 M3/hour as well as special designs (split flows, dual duty, heavy CO2 loads etc.).

 Used for: -

  • Heavy carbon dioxide loads
  • Split flows
  • Dual duty
