Whitepaper: Fan-and-Filter Units to Cool Industrial Enclosures

EIN Rittal fan filter 400

August 12, 2021

As electronic components become increasingly smaller and are positioned closer together in the enclosure, they become ever more sensitive to external factors such as dust, oil, and temperature. High temperatures are “enemy number one” for sensitive components. Heat must be dissipated effectively and permanently so that these components can function properly. There are several methods for dissipating this heat, including natural convection, fan-and-filter units, air/ air and air/water heat exchangers, and cooling units. Each of these options has its advantages and disadvantages. This white paper describes the basic principles involved in choosing a fanand-filter unit to cool an industrial enclosure. It discusses when you can use a fan and filter unit instead of another cooling solution. And it tells you how to calculate the necessary fan and filter unit and what you will need to bear in mind.

Heat must be dissipated from the enclosure to help ensure the proper operation of the electronic components. This can be done in a number of ways, including: natural convection, fan and filter units, air/air heat exchangers, air/water heat exchangers and cooling devices. A fan and filter unit is a good and effective way of dissipating heat, and also the most economical alternative. If you want to use a fan and filter unit, it is important to calculate how much capacity (airflow) is needed and how much airflow the proposed fan and filter unit actually delivers in combination with an outlet filter. This is the only way to help ensure the desired temperature in the enclosure and provide you with an optimal situation for your components.

    Convergix: 4 Ways Automated Packaging Can Transform Logistics

    Automated packaging solutions have a host of benefits for any manufacturing business. But the material handling capabilities of robotic technology and leading-edge automation software aren’t limited to packing items in containers. There’s more to getting your products from the factory floor to the loading dock, and automation provides opportunities to increase productivity at every step along the way. Packaging automation technology touches every aspect of logistics, and the advantages add up—especially in warehouses and distribution centers, where storage, transport, packing, and shipping make up a larger part of day-to-day activities. Introducing automation to any one task can streamline your storage and shipping. But if a larger network of automated systems is right for your business, it can transform your logistics and distribution operations.

    Electronics Manufacturing Meets Enhanced Safety & Efficiency

    In electronics manufacturing, every minute counts. PT-Elektrik understands this very well. That’s why they have decided to optimize their quality assurance processes with advanced robotics and innovative software solutions to meet increasing demands. The SICK safety system sBot Speed URCap is making their processes not only more efficient, but also safer. PT-Elektrik, a recognized name in automation and quality assurance, utilizes a universal robot e-series (also known as a URe robot) to set new standards in its quality assurance process for printed circuit boards (PCBs). Because the robot’s working area is near to other test stations used by people, the area around the robot needed to be safeguarded. The solution had to be simple, and quick to implement.

    Building Towards Autonomous Operations

    What is consistently heard from industry leaders is the need for real-time visibility across their global operations, which is key to ensuring their operations stay agile and scalable. However, achieving this isn’t possible without removing laggy manual data collection through the deployment of connected assets and contextualized data. By eliminating data silos and unlocking industrial data and artificial intelligence (AI) capabilities, companies can enable autonomous decision-making that optimizes costs, efficiency, and production resilience. This moves their organization closer to achieving autonomous operations. Manufacturing operations, in particular, have seen progress through Model Predictive Control (MPC), which continuously analyzes real-time and forecasted data to optimize process control within defined constraints. While MPC is a strong example within manufacturing, broader autonomy demands extending similar intelligent systems across the enterprise. This journey is captured in the industrial AI maturity pyramid, which outlines a progression from basic data integration and visualization to predictive analytics, prescriptive decision-making, and ultimately, autonomous operations. As organizations climb this pyramid, they adopt machine learning, real-time automation, and self-learning systems. Each stage requires not just technological upgrades but also cultural and structural transformation.
