As one of the earliest suppliers of specialized frequency converters for the water supply and sewage treatment industry, Danfoss has always closely followed the development of the water industry and continuously provided innovative impetus to the industry. By combining deep professional application knowledge with powerful frequency converter technology, Danfoss can not only save energy and reduce carbon footprint, but also help industry users transform from energy users to energy producers.

1、 VLT ®  AQUA Drive Danfoss FC202 frequency converter

VLT developed by Danfoss based on years of deep cultivation in the water and sewage industry ®  The AQUA Drive series frequency converters are durable and can withstand harsh production environments, ensuring low fault operation of any type of water treatment facility anywhere in the world. The combination of stable design and advanced real-time analysis capabilities ensures that enterprises achieve significant energy-saving benefits and achieve first-class sustainable and economical water management standards.

What is the working principle of real-time analysis?

Combining the latest edge computing technology patented by Danfoss, VLT ®  AQUA Drive has been updated. By monitoring the operation of motors and pumps, timely handling of faults can ensure long-term normal operation of the factory and reduce operating costs. By collecting data several times per second, the edge computing solution ensures that any measured value outside the normal range will trigger a warning, thus minimizing the risk of abnormal operation of the device.

As an expert in the water and sewage industry, Danfoss can provide multiple products to meet the different needs of the industry and contribute "digital intelligence" to its development.

Using VLT ®  AQUA Drive can adjust pump speed to adapt to constantly changing loads during operation by simply installing a frequency converter, thereby achieving energy-saving goals. In addition, it can also save up to 15% of the energy cost of annual frequency converter configuration investment.

VLT ®  AQUA Drive

Danfoss takes the lead in real-time monitoring of pump and motor working conditions by embedding the edge computing function in the frequency converter. By combining with the unique hot switching technology for multi pump control and advanced active filter technology for harmonic suppression, the system will basically achieve self maintenance, ensuring that the equipment maintains normal operation for a long time. In addition, specially designed intelligent software features can help protect assets, extend equipment lifespan, and reduce energy costs in various ways, including automatic cleaning of pumps, sleep mode, reducing the risk of water hammer, and safe cooling of deep well pumps.

By embedding cloud based artificial intelligence in frequency converters, devices can automatically define operational baseline parameters according to different specific application scenarios, at different speeds and actual working cycle states. In order to shorten equipment installation time, achieve predictive maintenance, reduce work costs, and extend equipment normal operation time.

2、 VLT ®  Flow Drive FC 111 Fluid Control Inverter

Danfoss's newly launched VLT in 2021 ®  Flow Drive FC 111 fluid controlled frequency converter, specifically designed to provide quality assurance for green water services.

Its innovative check valve monitoring function can provide owners with a basis for determining the valve disc closing position in secondary water supply systems. In order to avoid potential losses caused by inadequate valve closure and improve the efficiency of the water supply system.

In a parallel water supply system with multiple pumps, innovative functional development is carried out based on the common backwater problem caused by inadequate closure of the check valve. This function can monitor the status of the check valve body of the static pump circuit in the topology structure of a multi pump parallel water supply system when a single pump is running. If there is a large flow of return water, an alarm will be triggered. This function can provide system inspectors with check valve status warning information, and provide valuable time for equipment maintenance. At the same time, the return water rate of the check valve is reduced, which can also ensure the efficient and stable operation of the system.

3、 Danfoss DrivePro ® Life cycle service solution

Danfoss DrivePro ® The lifecycle service plan has been carefully designed, taking into account the conditions of the entire lifecycle of the frequency converter. It helps you to properly maintain the frequency converter, maintain excellent performance throughout the entire process, and fully extend the lifespan of the frequency converter. At the same time, it provides support for continuous production losses and production mode updates.
