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 […]
Different Types of Centrifugal Fans and Their Many Applications
Centrifugal fans are widely used across industrial and commercial environments because of their ability to generate consistent airflow and handle higher static pressure than axial fans. Their design allows them to move air through ducts, filters, and resistance-heavy systems while maintaining stable performance. At Aad Tech, we work extensively with forward-curved, backwards-curved, and EC centrifugal […]
How to Increase Your Industrial Cooling Tower Efficiency
Industrial cooling towers play a critical role in maintaining stable temperatures across manufacturing operations, chemical processes, pharmaceuticals, HVAC systems, and energy plants. As towers age, fouling, scaling, drifting, and mechanical deterioration slowly reduce performance which leads to higher energy bills and reduced cooling capacity. Improving cooling tower efficiency does not always require a major rebuild. […]
AHU Maintenance Tips for Efficient and Reliable Operation
Air Handling Units (AHUs) are essential for maintaining proper ventilation, airflow, and indoor environmental quality. Regardless of the building type or the AHU’s specific configuration, consistent maintenance is necessary to ensure reliability, hygiene, and energy-efficient operation. Below are universal AHU maintenance best practices applicable to all AHU designs, including modern beltless or EC fan–based systems. […]
5 Helpful AHU Troubleshooting Tips You Should Know
Even the most advanced HVAC systems depend on a well-functioning Air Handling Unit (AHU) to maintain indoor air quality, temperature, and humidity. When an AHU begins to underperform, whether due to poor airflow, uneven cooling, or incorrect humidification, the impact spreads quickly across the entire facility. Understanding how to identify and fix common AHU problems […]
