The Importance of Selecting the Right Cooling System

In the medical equipment industry, proper component functionality and performance is of utmost importance, as failures can cause dangerous malfunctions and delays that put patients at risk. When selecting a cooling system for your medical equipment application, it’s important to consider your project’s specific temperature and application needs. This will help to ensure longevity and reliability in your medical equipment.

Axial vs Centrifugal Fans

There are two primary varieties of fan, axial fans and centrifugal fans. Pelonis Technologies, Inc. (PTI), a global leader in fan technology for more than 25 years, manufactures both axial and centrifugal fans.

The design and function of a centrifugal fan is very different from those of an axial fan. Their differences make them each suited for different applications and customers are sometimes unclear as to which fan type will best suit their needs.

To help clear up that confusion, here is a breakdown of the fan types, their benefits, and their uses.

Direct current fans, or DC fans, have a variable, uneven flow. In contrast, alternating current fans, or AC fans, change direction 50 times a second in order to provide a constant flow.

Historically speaking, AC fans were typically less expensive than DC fans. Today, however, the price difference is negligible, which means you need to weigh the pros and cons of each fan type carefully when making a purchasing decision.

As summer’s temperatures reach their peak, keeping your facilities cool is important for maintaining comfortable working conditions. Cooling commercial spaces properly means finding the right balance for employee comfort, temperature/humidity control, and energy use. In manufacturing operations where additional heat is generated by machinery, and in warehouses where goods must be stored in constant environmental conditions, cooling systems are vital mechanisms.

Squirrel cage fans have a wheel with a number of fan blades that are all mounted around a central hub and they are also known as tangential or cross flow fans. Usually connected to the housing with a motor drive, the squirrel cage fan achieves air movement when the hub turns.

Air moves through the fan wheel, and then flows over the fan blades, exiting the fan. Its long history of use and simple design have made the squirrel cage fan one of the most reliable and frequently used fan types on the market today.
