VFD for HVAC Fans and Circulating Pumps

This application guide centers on HVAC fan and circulating pump drive selection using Boray catalog names. The catalog lists BR100 Variable Frequency Drive and BR110 Universal High-Performance Vector Inverter under variable-frequency-drive, and it also lists FS200 Series Intelligent Pump AC Drive and FS300 Series Intelligent Pump AC Drive under the same category.

Application framing

The page targets HVAC fans and circulating pumps as VFD applications. Boray’s catalog names relevant to this framing are BR100 Variable Frequency Drive, BR110 Universal High-Performance Vector Inverter, FS200 Series Intelligent Pump AC Drive, and FS300 Series Intelligent Pump AC Drive, all listed under variable-frequency-drive.

Fan drive references

For fan-side references, the catalog provides BR100 Variable Frequency Drive and BR110 Universal High-Performance Vector Inverter as named variable-frequency-drive entries. These are the Boray product names to cite when discussing HVAC fan control.

Pump drive references

For circulating pump references, the catalog provides FS200 Series Intelligent Pump AC Drive and FS300 Series Intelligent Pump AC Drive as named pump AC drive entries under variable-frequency-drive. These are the Boray product names to cite for pump control.

Catalog-based selection

Selection can be organized by catalog name: general variable-frequency-drive names such as BR100 Variable Frequency Drive and BR110 Universal High-Performance Vector Inverter, or pump-specific names such as FS200 Series Intelligent Pump AC Drive and FS300 Series Intelligent Pump AC Drive.

Project documentation

When documenting an HVAC fan or pump control project, list the Boray catalog names used: BR100 Variable Frequency Drive, BR110 Universal High-Performance Vector Inverter, FS200 Series Intelligent Pump AC Drive, and FS300 Series Intelligent Pump AC Drive. This keeps the reference tied to the catalog.
