VLT® HVAC Drives
make your building green
Expect optimisation
Danfoss’ long experience in applying 
drives in HVAC systems has enhanced 
its ability to off er a “Best in Class” 
technical expertise in integrating the 
drive into the overall system design to 
extract the maximum value from your 
initial investment and optimize the 
operational savings performance.
The 21st Century focus on energy 
 effi  ciency is not new with regards 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 
fi nancial cost.
Save energy 
and CO
2
 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 reduce the annual 
CO
2
 emissions with 12 million tons!
Makes the building perform
Today the prime focus is on the 
 overall performance of buildings 
including design, construction, 
effi  ciency, sustainability and the 
 environmental impact of these 
 buildings in the future. 
Energy effi  cient products form part of 
this overall plan. In most countries 
around the world this is now realized 
in the evaluation of high performance 
buildings under the banner LEED.
We off er you a wealth 
of knowledge
The various applications incorporated 
within high performance buildings 
are well understood by Danfoss and 
as global market leader we have built 
a wealth of knowledge and under-
standing of the applications and 
 developed products and technology 
to ensure we meet and determine 
 future trends in this industry. Our 40 
years of experience in this business 
has made the VLT® HVAC Drive the 
 industry  benchmark.
Premier drive in the market
The effi  ciency of the VLT® HVAC Drive 
and its built-in features make the VLT® 
HVAC Drive the premier drive in the 
market today. 
Danfoss application and industry 
knowledge will ensure that the 
investment made in VLT® drives
