Reliable and cost eff ective
Correct drive selection is critical to
reliability. Products that introduce
unacceptable levels of RFI or
harmonics into a building can prove
highly problematic and costly in
addition to breaking legislative
regulations.
Danfoss’ many years of experience in
the application of VLT® drives and in
the HVAC industry in particular, has
resulted in a global team focused on
delivering the best drives solution,
ensuring total security of your
investment.
Minimum impact
on the environment
Having chosen to fi t a VLT® drive as
part of the building control architec-
ture, the lifetime sustainability of this
product is an important aspect.
New regulations are forcing manufac-
turers to look at how they manufac-
ture, what they manufacture and with
what materials.
Are products harmful to make? Are
they harmful to dispose of at their
end-of-life? Danfoss complies with
RoHS, WEEE Directives, ISO14001 are
all standards and directives created to
ensure the minimum impact on the
environment.
Energy monitoring
The VLT® HVAC Drive provides a
complete range of energy consump-
tion information. Choose to divide
absolute energy consumption into
hours, days or weeks or to monitor a
load profi le for the application.
VLT® Energy Box software is
the most modern and
advanced energy calculation
tool available.
It allows energy consumption calcula-
tions and comparisons of HVAC fans,
pumps and cooling tower applications
driven by Danfoss drives and alterna-
tive methods of fl ow control.
The program compares the total
operation costs of various traditional
systems to operation of the same
system with a VLT® HVAC Drive.
With this program it is easy to evaluate
the savings by comparing a VLT® HVAC
Drive over other types of capa city
control systems in both new installa-
tions as well as retrofi t situations.
Complete fi nancial analysis
VLT® Energy Box provides a complete
fi nancial analysis including:
■ Initial cost for the drive system and
the alternative system
■ Installation and hardware costs
■ Annual maintenance costs and any
utility company incentives for
energy conservation products
■ Payback time and accumulated
savings
■ Upload of actual energy consump-
tion (kWh) and duty cycle from the
VLT® HVAC Drive
VLT® Energy Box makes it possible to
capture actual energy data from the
drives and monitor energy consump-
tion and overall system effi ciency.
Energy audit
The VLT® HVAC Drive coupled with
Energy Box software enables the
package to be used as the Energy
Audit equipment for both estimation
and validation of savings.
VLT® HVAC Drive can be interrogated
remotely for full energy data, making
it easy to monitor your energy savings
and return on investment. Monitoring
via fi eldbus often makes energy
meters omissible.
