3 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 a HVAC unit or panel, reducing overall enclosure costs and freeing up panel backspace for other devices. Fire Override Mode Fire Override Mode helps keep fire escape routes free of smoke, overrides the drive’s self-protecting features and keeps the driven equipment...

4 VLT® HVAC Drive for Green Buildings Danfoss commitment 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 optimise the operational savings performance. The 21st Century focus on energy efficiency is not new as regards energy saving but the emphasis on the consequences of wasted energy and the over-use of fossil fuels to produce energy is top of the agenda. Climate Change is seen as a cost to the...

5 Financial incentives are just as important as moral incentives to make people choose energy efficient solutions. 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. Minimum...

6 Benefits of ownership Total Cost of Ownership is an organisation’s total cost of acquiring, operating and maintaining a system through a given lifecycle. 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”. We understand the needs of our customers operating their facilities in a competitive environment which requires total system cost effectiveness and highest efficiency in daily operations with environmental sustainability. Dedicated HVAC organisation Customer assurance...

7 Enhanced advanced monitoring Enhanced advanced application monitoring functionality for fans allows you to keep track of the status of pumps and compressors. This can mean increased lifetime, reduced maintenance costs, and less downtime. 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...

8 The modular VLT® HVAC Drive 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. 1 Fieldbus option • BACnet • LonWorks • Profibus • DeviceNet 2 Local Control Panel (LCP) Choose numerical, graphical or no display 3 I/O option • General Purpose I/O (3DI + 2AI + 2DO + 1AO) • Analogue I/O option (3AI (0 – 10 V / PT1000 / NI 1000) + 3AO (0 – 10 V)) • Relay output (3 x relays) 4 24 V supply option 5 RFI filter Built-in RFI filter for long motor cables compliant with the IEC 61800-3 and EN 55011 standards....

9 Optimising Energy Savings Automatic Energy Optimisation The standard feature AEO provides optimised motor magnetisation at all speeds and loads. This optimisation 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. Suitable for “follower” operation The drive’s modular structure makes it suitable for “follower” operation mastered by BMS, PLC’s or DDCs. The open communications drive Motor current Speed Motor voltage Automatic load adjustment Start with high...

10 Perfect for all conditions The installation volume and/or the mounting surfaces are reduced by up to 60% compared to the previous series. The functional sections nevertheless fulfil the highest requirements even for applications with high overload, long motor cables and ambient temperatures up to 50° C (55° C with derating). Optimised design Optimised efficiency and intelligent cooling technology make for a compact and service-friendly design. Supplementary equipment such as EMC filters, harmonics suppression and brake modules are integrated into the enclosure. Save installation time The IP...

11 High reliability even in harsh environments An external watertight USB plug connected to the control card inside IP 55/66 enclosures makes USB access easy. The VLT® HVAC Drive is also available with a mains switch option. This switch interrupts the mains supply and has a free useable auxiliary contact. All VLT® HVAC Drive versions have manganese phosphor rear bodies. IP 66 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...
