Gravity Ventilation - Industrial Ventilation for Aluminium Smelters

Colt can provide natural or gravity ventilation systems for smelters that harness the natural elements to create ideal internal working conditions.
Colt provides a complete package of scheme design, manufacture, installation, commissioning and maintenance.

    Benefits of gravity ventilators:

  • use virtually no energy
  • require virtually no maintenance
  • are silent in operation
  • cost nothing to operate
  • have a long life span

    Benefits of working with Colt:

    Having one partner who is responsible for design, delivery, installation and performance of the ventilation system

Leaflet: Gravity ventilation in heavy industries (0.7 MB)


The demand for aluminium is growing. This can be achieved by building Greenfield smelters, upgrading existing smelters or modification. Whatever the choice, in every circumstances there will be a need for ventilation in order to guarantee a good indoor climate for the people who are working in the primary aluminium industry. Several parameters influence the final result:

  • Building related parameters, like dimensions, location, openings, the construction
  • Heat load
  • Air inlet possibilities
  • Weather conditions
The above parameters will be conducted in a calculation and tested. Colt is using the newest technologies, such as CFD.

 
 

Gravity ventilation: specific advantages


Gravity ventilation makes sure a healthy indoor climate will be the result and temperature control and a clean atmosphere on working level is the case. Special attention is given to avoid turbulence at working level. Furthermore the advantages of gravity ventilation will be the same as for all other natural ventilation systems.
