Energy Box Software allows energy
consumption comparisons of HVAC fans and
pumps driven by Danfoss drives and alternative
methods of flow control. This tool may be used
to project, as accurately as possible, the costs,
savings, and payback of using Danfoss adjustable
frequency drives on HVAC fans and pumps.
