Fan Upgrades

Fan Upgrade
Direct Drive Centrifugal Plug Fan

With the evolution of fan technology over the past 10-15 years, belt driven centrifugal fans have become a thing of the past for HVAC applications. Direct drive plug fans or modular fan wall technology are now standard for new air handling equipment.

Direct-drive plug fans offer the following advantages:

  1. Fewer moving parts, thus less wear and tear
  2. No power transmission losses
  3. Up to 15% more efficient than traditional belt driven fans
  4. Reliability: Fewer points of failure
  5. Maintenance: Reduced maintenance, fewer invasive shutdowns for preventative maintenance tasks.
  6. Belt tensioning & alignment issues are eliminated
  7. Grease points can be tubed to externally mounted, further eliminating shutdown requirements.
  8. Compact: Smaller footprint, space saving design

CES can assess each clients existing air handling equipment on a case by case basis, and advise on the best options available to upgrade & modernise, with a view to improving system reliability and energy performance.

Furthermore, CES can undertake all upgrade works on a turnkey basis to include equipment design, specification & supply, electrical attendances, mechanical installation through to commissioning & handover.
