Lowest cost of ownership
VLT® HVAC Drives let you:
• Save energy
The VLT® HVAC Drive includes:
– 98% basic energy efficiency
– Sleep Mode
– Automatic Energy Optimisation
– Flow compensation
• Save money
The modular design and a host of options allows for a low initial investment
and low cost upgrades according to future needs.
The VLT® HVAC Drive, built on Danfoss’ new modular plug-and-play platform
and dedicated to HVAC applications, makes HVAC operation child’s play.
Save time
Operators, equipment and control systems all communicate effortlessly with
the VLT® HVAC Drive. It is fluent in all common BMS network protocols and
displays every alphabet. 27 languages, including English, German, Mandarin
and Cantonese are available.
The award-winning Local Control Panel constantly improves on the intuitive
man-machine interface. Automatic Motor Adaptation and Automatic Energy
Optimisation support fast commissioning.
Due to a series of self-protecting and monitoring features and a highly
durable mechanical design, the VLT® HVAC Drive is practically maintenance
free.
Save space
Due to its small size, the VLT® HVAC Drive is easily mounted inside a HVAC
unit or panel.
• Fire override mode
Fire Override Mode helps keep fire escape routes free of smoke, over-rides
the drives’s self-protecting features and keeps the fan running as long as
possible in the event of fire.
• Save cabinet
Protection class IP55 requires no cabinet.
Dedicated to HVAC
Danfoss has unequalled experience in advanced drive technologies for HVAC
applications.
This experience has been used to optimise features in the VLT® HVAC Drive
and make it the perfect match for pumps, fans and water chillers
(compressors) in buildings fitted with sophisticated HVAC solutions.
Unleash the Full Potential of HVAC
Small investment
The VLT® HVAC Drive is available in a range of versions, from a basic serial
communication and I/O configuration capable right up to a fully equipped and
personalized drive, including all relevant HVAC I/O points and protocols.
Delivered from factory. No extra assembly work on-site!
50° C ambient temperature
The robust VLT® HVAC Drive is designed to work at maximum output in an
ambient temperature up to 50° C.
Suitable for “slave” operation
The drive’s modular structure makes it suitable for “slave” operation
mastered by BMS, PLC’s or DDCs.
Stand-alone unit
VLT® HVAC Drive provides intelligent stand-alone functionality via:
• Built-in Real Time Clock
• Programmable actions
• Smart Logic Controller
• 4 auto-tuned PID controllers.
Automatic Energy Optimisation
The standard feature AEO provides optimized motor magnetisation at all
speeds and loads. This increases energy efficiency by 5-15% at partial
loads.
Flow compensation
Significant energy savings and reduced installation costs are provided by
flow compensation in both fan and pumps systems. A pressure sensor mounted
close to the fan or pump provides a reference enabling pressure to be kept
constant at the discharge end of the system. The drive constantly adjusts
the pressure reference to follow the system curve.
Energy monitoring
The VLT® HVAC Drive provides a complete range of energy consumption
information. Choose to divide absolute energy consumption into hours, days
or weeks. Or choose to monitor a load profile for the application.
Energy analysis
This data can even be uploaded to a VLT® Energy Box – PC software that
performs in-depth real life/true energy analysis of your application and
displays the payback time for the drive.
