Project #8 – Return Fan Replacement

Project #8 – Return Fan Replacement


Scope of Work:


The Challenge: Return Fan Compromising HVAC Reliability

The 20th floor return air system relied on an outdated tubular inline fan assembly that no longer provided reliable airflow or efficient operation. The existing unit required full disconnection, demolition, and disposal, as it could not meet the building’s airflow, static pressure, control, or integration requirements.

  • Restore reliable and consistent airflow
  • Better system control & visibility
  • Improve energy efficiency
  • Reduce operating costs
  • Enhance comfort with less noise inside
  • Reduce vibration to minimize equipment wear
  • Decrease frequent maintenance & repairs
  • Extends lief of HVAC connected equipment

TurboChyll provided a turnkey replacement of the system including:

  • Removal and disposal of the existing tubular inline fan.
  • Supplied and installed a new 12,000 CFM, 7.5 HP tubular inline direct-drive fan with premium-efficiency TEFC motor.
  • Installed VFD controller featuring BACnet touchscreen integration.
  • Added airflow monitoring and pre-wired 25' EC whips (230/3 voltage).
  • Installed the new fan and completed all wiring and system start-up.
  • Trained engineering staff on fan operation and controls.
  • Customer support with a 1 year TurboGuard Plus parts & labor warranty.

Delivered Results & Value

The new fan will restore stable airflow, improve energy efficiency with VFD and BACnet controls, and decrease maintenance through its direct-drive design. Engineering staff received training for system operation, and the one year TurboGuard Plus warranty will ensure reliability and peace of mind.
