How to Calculate Cooling Tower Efficiency?
If you’ve ever managed a facility that uses a cooling tower, you’ve likely paused mid-operation and asked yourself, Is this system really performing as well as it should? The performance of a cooling tower isn’t just a technical concern; it directly influences operational cost, process consistency, and even equipment longevity. Knowing how to calculate cooling […]
Top 7 Clean Room FFU Manufacturers Ensuring a Clean and Processed Air Supply
Cleanrooms are environments where precision matters, and air quality is not just a comfort factor but a critical part of product integrity. Whether it’s semiconductor manufacturing, pharmaceutical processing, or medical device assembly, the quality of the air being supplied can mean the difference between success and costly contamination. For these spaces, clean room air filtration […]
Comparison of Different Types of Air Handling Units
Air handling units sit quietly behind walls, ceilings, and plant rooms, yet they shape how a building feels every single day. From temperature and airflow to air quality and energy use, almost everything depends on how well the AHU is designed. This often leads building owners and facility managers to pause mid-discussion and ask themselves, […]
Why EC Fans Are the Future of Cooling in Data Centers and Telecom
In today’s hyperconnected world, data centers and telecom networks quietly power almost everything we do, and somewhere between a video call and a cloud backup, you may find yourself wondering where all that heat actually goes. Every stream, every transaction, every computation generates electrical activity, and when operators pause mid-operation to ask themselves how much […]
Why Get an Air Handling Unit Refurbishment?
Have you ever stepped into a building and felt the air was heavier than it should be, even though the system was technically running? In many cases, the issue does not lie with the building itself but with an ageing air handling unit that has slowly lost efficiency over time. This is where the idea […]
Top 7 Centrifugal Fan Uses in Heavy Industries
Heavy industries depend on airflow systems that remain steady through hours of operation, and somewhere in the middle of a long shift, you might think – How does a fan keep delivering this much pressure without falling behind? That single thought usually opens the door to real curiosity, because once you start noticing how often […]
Different Types of Axial Fans
The axial fan is one of the most widely used airflow devices in ventilation and cooling systems. Its design moves air along the axis of rotation, creating a smooth and directed pattern suited to industrial lines, commercial buildings, cleanrooms, and large utility areas. Engineers compare the many types of axial fans available because each model […]
EC Motor Fundamentals: What Is an EC Motor and the Benefits It Offers
As energy costs rise and demands for efficient ventilation grow, the choice of fan motor becomes critical. Among modern motor technologies, the EC motor (Electronically Commutated motor) stands out for delivering high efficiency, precise control, and long-term reliability. At Aad Tech, we recommend EC-motor fans, whether centrifugal or axial, when retrofitting air-handling units (AHUs), cooling […]
How a Fan Filter Unit Works in a Cleanroom Environment
Cleanrooms depend on controlled airflow and high-efficiency filtration to keep sensitive processes free from airborne contamination. Whether used in pharmaceuticals, electronics, biotechnology or medical device manufacturing, the goal is always the same: maintain a stable, particle-free environment that meets strict standards. One of the most effective ways to deliver clean, filtered air into these spaces […]
What Is an Axial Fan? Features and Applications Explained
Axial fans are one of the most common air-moving devices in industrial and commercial environments. They move air along the axis of rotation—so air enters on one side of the hub and exits on the other in the same direction. This allows them to move large volumes of air with relatively low resistance, making them […]
