Hospital Kitchen Exhaust Fan

A hospital in Indianapolis needed to replace a very old kitchen exhaust fan and ductwork. This was a joint effort between Horner Fan and Fab and Horner Field Service led by Sales Jeff Wilson.

The controls were changed from a simple on/off to a VFD that was tied into the building management system as well as reprogramming of the VFD to achieve the desired CFM of air flow. Thanks to everyone who worked over a weekend!

Due to the damage and loss of pertinent feedback to monitor quality, our customer made the decision to replace the existing drive with a new Bardac DC drive. Bardac was chosen due to the availability of the drive which was 2 weeks out on an expedited basis. No other drive company could provide delivery inside 16-18 weeks. David Whited, [...]
