Danfoss VLT HVAC BasicDrive FC 101 series vfd makes your buildings perform.

Danfoss commitment.
Danfoss’ longstanding experience in applying drives in HVAC systems has enhanced its ability to offer technical expertise integrating the drive into the overall system design to extract the maximum value from your initial investment and optimize your operational savings performance. The 21st Century focus on energy efficiency is not new with regard to energy savings emphasis on the consequences of wasted energy and 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 not just simply a financial cost.

Save energy and CO2 emission.
VLT® frequency converters save more than 20 million MWh energy globally each year. This is equivalent to the annual electricity consumption of 5 million homes. This energy saving reduces annual CO2 emissions by 12 million tons.

Building performance.
Today the prime focus is on overall buildings performance which includes design, construction, efficiency, sustainability and the environmental impact of buildings in the future. Energy efficient products form part of this overall plan. In most countries around the world the evaluation of high performance buildings falls under the banner LEED.

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 developed products and technology to ensure we meet and shape future trends in this industry. Danfoss application and industry knowledge will ensure that the investment made in VLT® drives provides a qualified return. 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. Solutions that introduce unacceptable levels of RFI or harmonics can prove highly problematic and costly in addition to violating 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 drive solutions, ensuring total security of your investment.

Minimum impact on the environment.
When choosing a VLT® drive as part of the building control architecture, the lifetime sustainability is an important aspect to concider. New regulations are forcing manufacturers to look at how they manufacture, what they manufacture and with what materials they use in manufacturing their products. Are the products harmful to make? Are they harmful to dispose of at their end-of-life? RoHS, WEEE Directives, and ISO14001 are all standards and directives created to ensure minimum impact on the environment.

EMC compatible.

EMC protection coupled with harmonic filters ensures that the EMC environment and power supplies are maintained undisturbed throughout the operational lifetime of the system, negating any reduction in lifecycle costs. VLT® HVAC Basic Drive meets the EMC product standard EN 61800-3 without additional external components and corresponds to the EMC guidelines 2004/108/EC, offering performance superior to other drives. Critical for practical use is compliance with the environment standard EN 61800-3, class C1 (residential) and Class C2 (industrial area). This ensures reliable plant operation through full compliance with all EMC requirements, product standards, prescribed warnings, and restrictions. Integrated DC chokes minimise the network effects dramatically and thus maintain operation within the limits of EN 61000-3-12. These chokes also make the VLT® HVAC Basic Drive stable and dynamic even during short supply voltage drops or other poor network conditions.

Managing harmonics with Danfoss VLT HVAC BasicDrive FC 101 series frequency inverter.

Harmonic distortion on the supply grid is an increasing problem, mainly caused by electronic power devices including frequency converters, drawing non-sinusoidal current from the mains supply. This creates harmonic distortion on the supply depending on the supply impedance. Danfoss’ Harmonic Calculation Software MCT 31 makes it possible to calculate the extent of these harmonics at the planning stage and can suggest mitigation countermeasures. Harmonic mitigation can be particularly valuable when the power supply is backed up by emergency generators, which have poorer tolerance to non-sinusoidal currents.

Current standards (EN 50106) are included in the software analysis tool which can quickly and easily be downloaded from Danfoss webpage. Data can be entered, stored and recalled project by project. At a click the software presents a clear overview of each project with data presented in both tabular and bar-chart formats.

Enhanced safety built-in inside Danfoss VLT HVAC BasicDrive FC 101 series drive.

Fire Override Mode.
Activating the function “Fire-mode” within the VLT® HVAC Basic Drive ensures secure and continued operation within applications such as stair-well pressurization, car park exhaust fans, smoke exhaust and essential service functions.

Clearly indicated.
Fire mode is clearly indicated on the display to prevent any confusion. When set, the drive will override self protection and will continue operation despite the possibility of permanent damage in case of overheating or overload. The vital goal is to keep the motor running even if it means self-destruction.

Typical application.
Smoke extraction from traffic tunnels, subway stations, stairwells.

For simple pump applications.

The VLT® HVAC Basic Drive offers pump-specific features developed in cooperation with OEMs, contractors and manufacturers around the world.

Sleep Mode.
In Sleep Mode the drive detects situations with low or no flow. Instead of continuous operation, Sleep Mode boosts the system pressure and then stops to save energy. The drive starts automatically when the pressure falls below the lower set point.

For simple fan applications.

User-friendly, distributed intelligence and reduced power consumption are beneficial for fan applications.

Basic AHU functions.
This enables the HVAC Drive to control a wide range of functions, including:
– Fire Override Mode.
Fire Override Mode prevents the VLT® HVAC Basic Drive from stopping for self-protecting reasons. In this mode it will continue vital fan operation regardless of control signals, warnings or alarms.
– 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 reduces vibration, noises and wear on equipment.
– Stairwell Pressurisation.
In the event of fire, the VLT® HVAC Basic 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.
– Belt Monitoring.
The drive can from the speed/current detect the case where the motor have lost contact to the fan and throw an alarm.
– Flying start.
The drive can detect speed and direction of a freely spinning fan or fan and “catch” it at the right frequency. This feature prevents violent starts and tear on the equipment.

VLT® Motion Control Tool.

Set-up software provides easy control of details as well as a general overview of drive systems, large or small. The tool handles all drives-related data.

Explorer-like interface.
The MCT 10 software features explorer-like interface design and functionality to ease both use and learning of the facilities.
