Energy Box software allows energy
consumption comparisons of HVAC fans and
pumps driven by Danfoss frequency converters
and alternative methods of flow control. Use this
tool to project the costs, savings, and payback of
using Danfoss frequency converters on HVAC
fans, pumps, and cooling towers.
Danfoss technical literature is available in electronic form
on the documentation CD that is shipped with the
product, or in print from your local Danfoss sales office.
