Do you know what a "master-level" frequency inverter is?
Danfoss VLT® AQUA Drive inverters are designed for masterful performance, combining deep application expertise with powerful drive technology. Through a wholehearted commitment to skill and technical excellence, they make your water applications easier and more efficient than ever before, enabling sustainable and economical water management.
Danfoss not only saves installation costs and improves installation efficiency, but also enables trouble-free operation.
High cost-effectiveness and trouble-free operation
VLT® AQUA Drive frequency converters are durable and can withstand the harshest operating conditions, ensuring trouble-free operation of any type of water treatment facility.
The robust design, combined with advanced software-based solutions, ensures significant energy savings and helps customers achieve best-in-class sustainable and economical water management.
01 Save on installation costs
VLT® AQUA Drive inverters feature a space-saving design, unique heat transfer technology, a new multi-pump controller, standard long motor cables and PCB protection, and user-friendly commissioning capabilities. Compared to traditional inverters, VLT® AQUA Drive installation and commissioning solutions can save up to 15% on installation costs.
02 Higher energy efficiency
VLT® AQUA Drive frequency converters can save you up to 15% on equipment investment costs annually. Furthermore, the simple installation of the frequency converter allows for customization based on different loads in water treatment applications.
Adjust the pump speed to save more energy.
03 Trouble-free operation
Smart features specific to the water industry ensure that water applications maintain long-term uptime while achieving energy savings.
Integrated condition monitoring capabilities enable customers to quickly assess and respond to emergencies such as blockages, leaks, motor winding failures, vibration and wear, mechanical misalignment, and wear.
How do frequency converters operate efficiently and save energy?
The unique rear-mounted airflow cooling concept employs a fanless design, utilizing the differences in thermal conductivity between different materials and temperatures, as well as the latest technologies in heat transfer pipes, to transfer up to 90% of the heat out of the control room.
This rear-channel cooling system can remove heat while saving users up to 90% on air cooling system investment.
● Integrated state-based monitoring
Take motor and pump monitoring to a new level with the intelligent VLT® AQUA Drive inverter.
Integrated condition monitoring capabilities enable customers to respond quickly to emergencies such as blockages, leaks, motor winding failures, vibration wear, mechanical misalignment, and wear.
The cloud-based artificial intelligence embedded in the frequency converter automatically defines operating baseline parameters according to various specific applications, different speeds, and actual work cycles. This shortens installation time, reduces predictive maintenance, lowers operating costs, and extends uptime.
●Energy saving and harmonic suppression
The unique VLT® low-harmonic inverter, which integrates an advanced active filter, offers 2-3% higher energy efficiency than conventional AC inverters using active front-end technology. A sleep function at low loads ensures further energy savings.
● Descaling is performed to achieve consistently high pump efficiency.
The descaling function built into the frequency converter provides proactive maintenance through periodic or clog-triggered "cleaning cycles" to keep the impeller clean, thereby consistently improving pump efficiency.
●Energy and Water
The interdependence of energy and water, along with the ever-increasing global demand for energy, will have a profound impact on economic growth, environmental sustainability, and our overall future.
Finally, let's learn about Danfoss's strengths through a case study!
Transform the city's largest energy consumer into an energy producer.
Since 2010, Danfoss has partnered with the City of Aarhus to achieve intelligent automation, build smart models, reduce energy consumption, and test and develop new technologies. By adopting Danfoss's state-of-the-art solutions, the Marlissburg wastewater treatment plant generates energy from organic waste such as sludge, converting it into biogas for use as energy or fuel, and establishing a 24/7 sustainable water management model. The Marlissburg wastewater treatment plant not only minimizes energy consumption but also maximizes its net energy surplus.
As the world's first energy-water balance system, this project operates on energy conservation and domestic wastewater treatment capacity (without consuming external carbon energy), achieving energy neutrality for the entire water cycle system (water supply + wastewater). In 2016, it generated 150% of its required energy consumption in electricity, produced approximately 2.5 GWh/year of waste heat, and achieved a total capacity of approximately 230% of its required energy consumption. Water leakage rate decreased to 6%, and water prices decreased by 9%. The project has been recognized by the International Energy Agency as a leading example of wastewater treatment.
Danfoss VLT® AQUA Drive frequency converters, with their superior performance, improve energy consumption in the urban water sector. While operating efficiently, they reduce installation costs, save energy, and ensure trouble-free equipment operation, thus promoting sustainable urban energy development. In the future, Danfoss will continue to focus on water sector management, providing more high-performance frequency converter products and striving to achieve sustainable development goals.
You thought that was the end? Don't worry, Xiao Dan has more goodies for you, keep reading!
Danfoss will be present at the 2020 Shanghai International Water Treatment Exhibition, showcasing its innovative air conditioning, variable frequency drive, and terminal control solutions from Denmark to a wide range of industry users. This will help promote the sustainable development of China's water sector under urbanization and effectively address the increasingly prominent challenges of water scarcity, water pollution, and water ecosystem damage.
