As an installer or machine manufacturer (OEM), you always strive for the highest quality and reliability. In a world where machines are becoming increasingly intelligent and connected, this also means that the digital robustness of every component counts. A modern frequency converter is the beating heart of your system and requires built-in reliability.

Harmonic distortion, also known as harmonics, is a common problem in electrical installations. These are disturbances in the sinusoidal voltage and current in an electricity grid, which lead to poor grid quality, unreliability and even damage to equipment. They are caused by non-linear loads, such as frequency converters, switching power supplies, modern LED lighting and welding equipment.

Good news for building managers! Danfoss has developed a new generation of frequency converters that can significantly reduce the energy consumption of ventilation and climate control systems (AHUs).

Pump systems in utility buildings can be complex and challenging. From wear and tear to energy loss, many factors can affect performance. Fortunately, Danfoss frequency converters offer solutions that effectively address these issues.

The production line at Silmaco runs largely on Danfoss drives. During a Danfoss DrivePro® Site Assessment, carried out in collaboration with Breemes, it emerged that a certain type of frequency converter had long since been discontinued. Support for it had also recently been discontinued. To ensure continuity of production, Silmaco decided to replace these high-power drives as a preventive measure. ‘You don't always have a new 200 kW frequency converter available immediately.’ Together with Breemes, a replacement system was selected that was state-of-the-art.

Sissing Noord in Leek (Groningen) is an expert in the maintenance, renovation and construction of “wet” infrastructure, like movable bridges, pumping stations and locks. For the drives of these structures, itsme supplies the speed drives and, where necessary, also the technical know-how. For projects where Sissing Noord needs this knowledge, specialist itsme offers “some relief”.

Being able to shift gears quickly is crucial to the success of industrial automation projects. This refers not only to the delivery of components but also to decision-making. Short lines of communication are important here. That was the case in the project to control a washing line for plastic PET flakes, in which ATR Engineering and itsme teamed up closely. ‘The added value of our collaboration is being able to anticipate customer requests extremely quickly.’ Bringing ten years of experience in industrial automation to the table, Adrie van Triest started his own company in 2019. With a broad approach, ATR Engineering in Berkel-Enschot focuses on hardware and software engineering. ‘Our area of expertise is offering total solutions for industrial automation centred around the design of PLC controls. We will sit down with a customer to discuss pending automation issues and we will determine the needs and wishes for a project together in advance. We also offer flexible support for projects or commissioning.’ ATR Engineering is a small company currently employing four engineers from different disciplines. There is also a permanent ‘flexible shell’ of engineers and technicians available to help during peak periods.

At RBB, the production of concrete roof tiles runs on drives that mostly come from Danfoss and are up to 20 years old. Breemes assessed their status and made recommendations for maintenance, replacement and standardisation. As a result, the supplier provided its customer RBB with higher efficiency in terms of spare stocks of drives and energy consumption in production - and ultimately a better night's sleep.
