Does the motors on the proposed fan array have to be VFD driven or can we use ECM motors?

05/20/2025

As long as the motors can be controlled and varied through the BAS system individually, the method of motor control and power does not matter. Again, the motors must be able to be varied in speed independentaly and, through BAS, must be adjustable. IHS COR

A0001 2 5/19/2025 Technical

Does the owner want redundancy built into the fan array? Info given in SOW is the CFM, Static pressure, power rating, etc per the original schedule.

05/20/2025

Yes, that is one of the reasons we want to go with a fan array system.

Enough redundancy in the system so that if 1 fan were to go down we could maintain cfm and static pressure for the as designed system would be preffered. IHS COR

A0001 3 5/19/2025 Technical

Does the proposal need to include removing the chilled water piping in front of the AHU back to the mains to give clearance to remove the existing fan section? The isolation valves are at the pipe drops and not at the mains, this could require partial draining of the chilled water loop. 05/20/2025

If, in the contractors assessment, the chilled water piping will have to be moved or any other work needing to be done to the AHU to install the fan array or remove the old fan array, then that work shall be part of this project and included in the proposal. IHS COR

A0002 4 5/28/2025 Technical

Will TAB be required? If so will only the cfm need to be read at the unit to setup new fan array or will the entire duct and register system from AHU 10 need to be balanced?

05/29/2025

TAB will be required. It will not be required for a full AH10 downstream system to be TAB'd but for the Air handler itself to have differential pressure and CFM measured and reported after installation so that we know it is running as designed and as the air handler was meant to operate.
