MAKING MODERN LIVING POSSIBLE VLT® HVAC Drive For HVAC it has to be VLT® 1.5 mio VLT® HVAC Drives reliably perform tasks in HVAC systems. Rely on proven VLT® technology – now available PM motor control, offering efficient control of EC and IEC standard motors types. 56% Energy use reduction in Mumbai’s VSNL building. ‘Only by using Variable Frequency Drives in the HVAC system could we achieve this target’ – General Manager VSNL, India. www.danfoss.
VLT® HVAC Drive provide the lowest life-time cost The VLT® HVAC Drive is the safe choice for fan, pump or compressor applications. It provides a high flexibility with regard to the place of installation, range of available bus systems, broadest HVAC control intelligence and functionality, and respecting the building environment by offering the best EMC and harmonics behaviour in the market. nent magnet motors.
High ambient temperature Fire Override Mode EMC & network protection The robust VLT® HVAC Drive is designed 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 still at higher ambient temperatures to maintain operation of the HVAC system.
VLT® HVAC Drives make your building green Expect optimisation Danfoss’ long experience in applying drives in HVAC systems has enhanced its ability to offer 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.
Reliable and cost effective 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.
Danfoss VLT® HVAC Drive provide lowest cost of ownership ness and highest efficiency in daily operations with environmental sustainability. Total Cost of Ownership is an organization’s total cost of acquiring, operating and maintaining a system through a given lifecycle. Danfoss dedicated HVAC organization at your side Total Cost of Ownership includes initial acquisition cost and operating cost. Through its technology and experience, Danfoss can transform this into the “Benefit of Ownership”.
Supporting software tool Software tools are available to help design a system with minimal harmonics and best energy efficiency. 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 modular VLT® HVAC Drive – not too much – nor too little The VLT® HVAC Drive is built on Danfoss’ modular concept. Real plug-and-play adding and exchanging of options. Just upgrade instead of buying a new drive.
The VLT® HVAC Drive is hooked upon your net The VLT® HVAC Drive integrates and communicates seamlessly with all HVAC devices, mastered by Building Management Systems via the fieldbus. HVAC-specific features make it economical, flexible and user-friendly and make HVAC operation simple. With VLT® HVAC Drive it is possible to read all the inputs and control all the outputs on I/O options.
VLT® HVAC drives – optimized for installation in panels IP 20/Type 1 enclosures The installation volume and/or the mounting surfaces are reduced by up to 60% compared to the previous series. The functional sections nevertheless fulfill the highest requirements even for applications with high overload, long motor cables and ambient temperatures up to 50° C (55° C with derating). Optimized design Optimized efficiency and intelligent cooling technology make for a compact and service-friendly design.
High reliability in any environment All VLT® HVAC Drive versions have manganese phosphor rear bodies. IP66/Type 4x enclosed drives are suitable for installation in demanding environments (e.g. cooling towers). Cooling air is kept outside the device to prevent any pollution of the electronics. The surfaces are smooth and can easily be cleaned. The IP55/66, Type 4x series are designed for easy accessibility and time-saving installation.
The real effect of VLT® HVAC drives is – money-saving right through the chain Automatic Energy Optimisation The standard feature AEO provides optimized motor magnetization at all speeds and loads. This optimization program increases the energy savings gained by applying variable speed control. Automatic Motor Adaptation Enter the name plate data, and VLT® HVAC Drive automatically adjusts to the motor.
Keeps EMC on the safe side Optimum EMC protection coupled with integrated harmonic filters ensures that the optimum EMC environment and cleanest power supplies are maintained throughout the operational lifetime of the system, negating any reduction in lifecycle costs. VLT® HVAC Drive meets the EMC product standard EN 61800-3 without additional external components even when using long motor cables, and corresponds to the EMC guidelines 2004/108/EC, offering performance superior to other drives.

New! Smart Start Saves commissioning time Smart Start guides you through 10 basic steps for commissioning the VLT® drive and ensures a quick, safe and energy saving commissioning. Smart Start is activated at the first power up, after a factory reset, or from the quick menu. When activating the Smart Start feature, the drive will ask for information it needs to run the application.
Enhanced safety built-in Fresh air in Speed Easy to open doors Differential pressure Mains switch option Fire Override Mode This switch interrupts the mains supply and has a free useable auxiliary contact. The mains switch ensures the safety of staff during maintenance and cleaning operations.
Dedicated fan features User-friendly, distributed intelligence and reduced power consumption are beneficial for fan applications. Velocity-to-flow conversion The VLT® HVAC Drive is able to convert velocity pressure sensor values into flow values. Operators can therefore set the drive up to provide a fixed flow or fixed differential flow. This way both comfort and energy consumption are optimized. Using a pressure sensor instead of a flow sensor saves money.
Dedicated pump features The VLT® HVAC Drive offers a vast number of pump-specific features developed in cooperation with OEMs, contractors and manufacturers around the world. 1 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 drive speed – and supply is secured at lower flow. Sleep Mode In Sleep Mode the drive detects situations with low or no flow.
Dedicated compressor features Premium torque control The VLT® HVAC Drive has been designed to offer flexible, intelligent control of 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.
VLT® HVAC Drive projects 20 Dubai Metro Danfoss Drives deliver a total of 260 drives rated from 90 to 325 kW for the new metro in Dubai, United Arab Emirates, to operate exhaust fans and tunnel ventilation. Dubai Metro is projected to carry approximately 1.2 million passengers on an average day, and 355 million passengers per year.
