A new approach to air handling
January 30th 2008 As part of its Energy-Saver programme, Eaton-Williams has a new approach to air handling design in the form of its fan wall technology. Air handlers using the technology are said to be 6-10% more energy efficient.
Fan wall technology solves many of the problems usually associated with the upgrade of air handlers, particularly in older structures. At the same time it can increase efficiency and control temperature and humidity levels. It is suitable for both refurbishment projects, new build or any project requiring a solution where there are stringent size, reliability and noise criteria.
The design features the LKP fan wall array that can be adjusted by turning one or more fans off, enabling remaining fans and motors to be fully loaded at or near peak efficiency.
Variable speed drives permit adjustment of airflow rates by turning fans on or off and smaller fans reduce low frequency noise generation. Additional noise reduction is achieved by surrounding each fan on all four sides in the array with sound absorbing enclosures. The use of direct drive fan drives eliminates drive loses and improves mechanical efficiency by as much as five percent.
Additional efficiency improvements include an improved aerodynamic performance with the elimination of belt guards, large fan pedestals and much of the structure traditionally found in air handlers to support motors and belt drive mechanisms. More articles from Eaton-Williams Group Ltd: |
