High ambient temperature
The robust VLT® HVAC Drive is
design ed to work at maximum output
in an ambient temperature up to
50° C. At higher temperatures, the
drive will continue operation with
lower performance.
Automatic derating enables reduced
operation for a period of time at
higher ambient temperatures to
maintain operation of the HVAC
system.
Maintenance free
Due to a series of self-protecting
and monitoring features and a highly
durable mechanical design, the
VLT® HVAC Drive is maintenance free,
except for general cleaning.
No replacement of internal fans or
capacitors is required.
Save space
Due to its compact dimensions, the
VLT® HVAC Drive is easily mounted
inside an HVAC unit or panel, reducing
overall enclosure costs and freeing up
panel backspace for other devices.
Save energy
The energy consumption from HVAC
applications such as fans and pumps
rises with the cube of the ow.
That’s the reason why VLT® control of
such applications typically saves 48%
energy compared to on-o operation.
Fire Override Mode
Fire Override Mode helps keep re
escape routes free of smoke, overrides
the drive’s self-protecting features and
keeps the driven equipment running
as long as possible in the event of re.
Activating Fire Override Mode will
ensure the VLT® HVAC Drive ignores
“soft“ faults and alarms to continue
operation during essential services
such as a “ re” command.
Save cabinet
We o er a standard & integrated IP55/
Type 12 protection class equal to that
of the motor.
This eliminates the cost of a separate
enclosure and saves on the additional
installation costs associated with
installation in a remote location.
IP 66/Type 4x Indoor
for harsh environments
The IP 66/Type 4x enclosure option for
harsh environments can eliminate the
cost of a separate enclosure and
reduce the installation costs associated with remote installations.
EMC & network protection
Fully integrated EMC lters
eliminate the cost of installing
external EMC lters and secure
the highest integrity & fully tested
EMC performance.
All versions of VLT® HVAC Drive
comply as standard with EMC
limits according to the EN 61800-3
norm (page 13).
All A1 and B lter options are
available as factory built-in
options.
The standard integrated DC coils
also ensure low harmonic load on
the network within EN 61000-3-12
and increase the lifespan of the
DC link capacitors. They also
ensure that the drive can operate
motors to their full rated
performance.
For further protection against
harmonic disturbances of the
supply grid, Danfoss provides
passive solutions such as 12/18
pulse solutions and Advanved
Harmonic Filters (AHF).

technical expertise in integrating the
drive into the overall system design.
This extracts the maximum value
from your initial investment and
optimizes the operational savings
performance.
The 21st Century focus on energy
e ciency is not new with regard to
energy saving, but the emphasis on
the consequences of wasted energy
and the over-use of fossil fuels to
produce energy, is at the top of the
agenda.
Climate Change is seen as a cost to
the human race more than simply a
nancial cost.
Save energy
and CO2 emission
VLT® frequency converters save more
than 20 million MWh of energy
globally each year. This is equivalent
to the annual electricity consumption
of 5 million homes.
This energy saving reduces annual
CO2 emissions of over 12 million tons!

Supporting software tool
Software tools are available to help
design a system with minimal
harmonics and best energy e ciency.
Protection mode
As soon as the system detects a critical
status, (e.g. over-current or overvoltage) the frequency of the VLT®
HVAC Drive will automatically be
reduced and the modulation process
adjusted.
Due to its ability to limit its switching
operations, the VLT® HVAC Drive is
extremely reliable and robust.
The protection mode will – if
allowable – end after 10 seconds and
the frequency will be restored under
control.
Minimum 98% e ciency
The VLT® HVAC Drive sets new
standards with a minimum 98%
e ciency at full load. This reduces
initial costs and operating costs due to
the smaller heat load/air conditioning
requirement in the switchroom/
plantroom, thereby maximizing
energy e ciency. Every kW of losses
requires another ~0.5 kW of energy to
remove the heat.
Installed in an air conditioned switchroom, lower losses can easily result in
operating cost savings >5% – 10% of
the cost of the drive every year (based
on a typical load pro le, with the drive
operating 24/7). Also energy
consumption and CO2 emissions are
reduced.
High Ambient
Temp er at ur es
VLT® HVAC Drive is designed to
operate in ambient temperatures
up to 50o C with an autoderate
capability for higher temperatures in
order to maintain reduced operation
in extreme climate conditions.
In most cases, the VLT® HVAC Drive
will handle abnormal situations
without needing attention.
VLT® HVAC Drive will manage the loss
of a mains phase or a high mains
imbalance by autoderating speed and
load to maintain a period of reduced
operation, enabling technicians to
respond to the situation.
