Best HVAC performance
with VLT® HVAC Drive
Comfort for flight personnel
and passengers
Clean air and comfortable temperature supports comfort and soothes
frayed tempers. Air is moved, chilled,
heated, humidified and cleaned
effectively consuming a minimum
of energy and financial resources.
With VLT® HVAC Drive you get full
control of pumps, fans and compressors.
Healthy Environment
Patients thrive better breathing clean,
conditioned air. Autotuning PID
controllers ensure accurate control
of airflow, maintaining a positive
pressure in operating rooms to help
maintain hygienic conditions and
prevent cross contamination.
VLT® HVAC Drive can maintain a
negative pressure in isolation wards
as well, ensuring a healthy environment for all.
Where dust is critical
Cleanroom facilities for the production of micro electronics like semiconductor chips require special
precautions. The VLT® HVAC Drive
can meticulously control to maintain
air quality and humidity levels under
a variety of operating conditions,
including continued operation
during mains voltage fluctuations.
6
Treated like a guest
When walking into a hotel room you
should experience a mild, fresh, clean
smell and a feeling of comfort and
relaxation.
To provide this and at the same time
go easy on energy and operating
costs – choose a VLT® HVAC Drive.
Hot business
Let VLT® HVAC Drive provide a reliable,
comfortable environment for your
office staff. People should be able to
work efficiently without being
distracted by sudden changes in
temperature or humidity. Let a VLT®
HVAC Drive quietly and effectively
control the indoor climate, improve
work efficiency and help you keep
cool in a hot business environment.
The bottom line
The initial cost of HVAC is almost
negligible. Energy efficient control
of fans, pumps and compressors
– day and night, during opening and
closing hours – ensures maximum
economy and low running costs.
Let VLT® HVAC Drive impact your
bottom line.
District heating/Cooling
The larger the system, the larger the
savings that can be derived from the
use of VLT® HVAC Drive. Precise control of temperature, pressure and flow
is done by speed control of pumps
and fans – the best way to save
natural resources. The larger system,
the greater the power required – and
VLT ® HVAC Drives goes all the way.
7
An operating pump will normally consume more
power the faster it runs – according to a curve
determined by the pump and application design.
VLT® HVAC Drive will detect situations where the
pump runs fast but is not fully loaded – and
thereby not consuming adequate power. This is
the case when water circulation stops, the pump
runs dry or when when pipes leak.
8
Dedicated pump features in VLT® HVAC Drive
The VLT® HVAC Drive offers a vast
number of pump-specific features
developed in cooperation with OEMs,
contractors and manufacturers
around the world.
Pump Cascade Control Option
The Pump Cascade Control Option is
the most sophisticated controller on
the market.
It distributes running hours evenly
across all pumps, keeps wear and tear
on individual pumps to a minimum
and ensures that all pumps are in
great shape.
Vital water supply
Vital water supply can be assured in
the event of leakage or a broken pipe.
For example overload is prevented by
reducing speed – and supply is secured at lower flow.
Sleep Mode
In Sleep Mode the drive detects situations with low or no flow.
Instead of continuous operation it
boosts the system pressure and then
stops to save energy. The drive starts
automatically when the pressure falls
below the lower set point.
Dry Pump Protection and
End of Curve
Dry Pump Protection and End of
Curve relate to situations where the
pump runs without creating the desired pressure – as when a well runs
dry or a pipe leaks.
Auto tuning of the PI controllers
With auto tuning of the PI controllers,
the drive monitors how the system
reacts on corrections made by the
drive – and learns from it, so that
precise and stable operation is
achieved quickly.
Gain factors for PI are continuously
changed to compensate for changing
characteristics of the loads. This
applies to each PI controller in the
4-menu sets individually.
Exact P and I settings at start-up will
not be necessary – which lowers the
commissioning costs.
The drive sets off an alarm, shuts off
the pump, or performs another
programmed action.

10
Dedicated fan features
User-friendly, distributed intelligence
and reduced power consumption are
beneficial for fan applications.
Lower AHU costs
The VLT® HVAC Drive is fitted with a
built-in Smart Logic Controller and 4
auto tune PID controllers and can
control air handling functions with
fans, valves, and dampers. The building management’s DDC-’s are thereby
released and valuable data points (DP)
are saved.
Extends BMS capacity
When integrated into the BMS network, all the HVAC Drive I/O points are
available as remote I/O’s to extend
BMS’s capacity. For example, room
temperature sensors (Pt1000/Ni1000)
can be directly connected.
Resonance Monitoring
By pressing a few buttons on the
Local Control Panel the drive can be
set to avoid frequency bands at which
connected fans create resonances in
the ventilation system. This improves
building comfort.
Intelligent AHU functions
The VLT® HVAC Drive handles logical
rules and input from sensors, realtime functionality, and time-related
actions. This enables the HVAC Drive
to control a wide range of functions,
including:
Stairwell Pressurization
In the event of fire, the VLT® HVAC
Drive can maintain a higher level of
air pressure in stairwells than in other
parts of the building and ensure that
fire escapes remain free of smoke.
• Weekend and working-day
operations
• Cascaded P-PI for temperature
control
• Multi-zone pressure control
• Flow balancing between fresh
and outlet air
Fresh
air in
Belt Monitoring
From the relation between current
and speed, the VLT® HVAC Drive is able
to reliably recognize a broken belt.
Lack of air flow detected immediately,
first cost and down-time is reduced.
Fire Override Mode
Fire Override Mode prevents the VLT®
HVAC Drive to stop of self-protecting
reasons. In this mode it will continue
vital fan operation regardless of
control signals, warnings or alarms.

Dedicated compressor features
The VLT® HVAC Drive has been designed to offer flexible, intelligent control
of scroll, screw and centrifugal compressors, making it even easier to
optimize cooling capacity with constant temperature and pressure levels
for water chillers, and other typical
compressor applications in HVAC.
Replace a cascade with
a single compressor
The VLT® HVAC Drive provides the
same level of flexibility with one large
compressor instead of a cascade
of 2 or 3 smaller compressors.
The HVAC Drive operates all
compressors at a far more refined range of speeds than
normal – even above
nominal speed – meaning
that one large compressor is
now enough.
Set point in temperature
The VLT® HVAC Drive calculates the
actual room temperature from the
pressure in the cooling media and
refines compressor operation accordingly – without the need for additional software, sensors or controllers.
Fewer starts and stops
A maximum number of start/stop
cycles within a given period of time
can be set via the Local Control Panel.
Since start-up is the most critical part
of compressor operation (all parts of
the unit are under mechanical stress
before the system is sufficiently lubricated) this extends compressor
lifetime.
This calculation is also applicable to
the set point as well, so the desired
temperature is set via the Local
Control Panel – and not a pressure
value.
VLT® HVAC drive allows you to rethink your compressor operation.
Quick start-up
To extend life even further, the VLT®
HVAC Drive opens a bypass valve and
lets the compresser start quickly
without load.
The VLT® HVAC Drive provides 130%
break away torque and can give 110%
torque for 60 seconds in normal operation. This torque demand would
normally require larger and more expensive drives.
Flexible compressor mode operation even above
nominal speed and high break away torque for
start-ups allow for better control and major
savings.

What VLT® is all about
Danfoss Drives is the world leader among dedicated drives providers
– and still gaining market share.
Environmentally
responsible
VLT® products are manufactured with
respect for the safety and well-being of
people and the environment.
All activities are planned and performed taking into account the individual employee, the work environment
and the external environment. Production takes place with a minimum of
noise, smoke or other pollution and
environmentally safe disposal of the
products is prepared.
UN Global Compact
Danfoss has signed the UN Global
Compact on social and environmental
responsibility and our companies act
responsibly towards local societies.
EU Directives
All factories are certified according to
ISO 14001 standard. All products fulfil
the EU Directives for General Product
Safety and the Machinery directive.
Danfoss Drives is, in all product series,
implementing the EU Directive concerning Hazardous Substances in Electrical and Electrical Equipment (RoHS)
and is designing all new product series
according to the EU Directive on Waste
Electrical and Electronic Equipment
(WEEE).
Dedicated to drives
Dedication has been a key word since
1968, when Danfoss introduced the
world’s first mass produced variable
speed drive for AC motors – and
named it VLT®.
Two thousand employees develop,
manufacture, sell and service drives
and softstarters in more than one
hundred countries, focused only on
drives and soft starters.
Intelligent and innovative
Developers at Danfoss Drives have
fully adopted modular principles in
development as well as design,
production and configuration.
Tomorrow’s features are developed in
parallel using dedicated technology
platforms. This allows the development of all elements to take place in
parallel, at the same time reducing
time to market and ensuring that
customers always enjoy the benefits
of the latest features.
Rely on the experts
We take responsibility for every
element of our products. The fact that
we develop and produce our own
features, hardware, software, power
modules, printed circuit boards, and
accessories is your guarantee of
reliable products.
Local backup – globally
VLT® motor controllers are operating
in applications all over the world and
Danfoss Drives’ experts located in
more than 100 countries are ready to
support our customers with application advice and service wherever they
may be.
Danfoss Drives experts don’t stop
until the customer’s drive challenges
are solved.
Impact on energy savings
One year’s energy savings from the
annual production of VLT® drives will
save the energy equivalent to the
energy production from a power plant.
Better process control at the same time
improves product quality and reduces
waste and wear on equipment.
