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 […]
From Terminals to Hotels: How EC Fans Optimise Climate Control in Public Spaces
At Aad Tech, we have seen how public spaces like airports, hotels, and shopping complexes depend on precise and efficient climate control systems to maintain comfort and air quality. These environments run round the clock, accommodating thousands of people each day. As energy demands increase, traditional HVAC systems struggle to balance comfort with sustainability. That’s […]
AHU Decarbonisation: The Complete Guide
At Aad Tech, we believe that achieving sustainability in building operations starts with smarter engineering. One of the most effective ways to cut energy consumption and carbon emissions in HVAC systems is through AHU decarbonisation. Air Handling Units (AHUs) are at the heart of every ventilation and air conditioning system. They control temperature, humidity, and […]
Cooling Tower Cleaning Frequency and Why Timing Matters
At Aad Tech, we’ve learned that one of the most overlooked aspects of industrial cooling performance is timely cleaning and maintenance. Cooling towers work continuously to reject heat, but in doing so, they collect dust, organic matter, and mineral deposits. Over time, this buildup can dramatically reduce efficiency and even shorten equipment life. Regular cleaning […]
Indirect Cooling Technology Optimises Fertiliser Production and Quality
At Aad Tech, the parent company of Melfrank, we understand the critical role temperature control plays in fertiliser production. From granulation to crystallisation, each stage demands precise cooling for optimal quality and efficiency. In this context, indirect cooling technology has emerged as a reliable solution offering superior control, water savings, and improved cooling efficiency of […]
8 Reasons Why EC Technology & Its Applications Are the Future of HVAC Retrofits
Table of Contents The Energy Challenge That Demands Innovation Buildings consume nearly 40% of total energy in the U.S., with HVAC systems accounting for almost 50% of that (U.S. Department of Energy, 2023). Fans alone contribute significantly to that consumption. Retrofitting traditional belt-driven systems is no longer optional. Rather, it is essential for reducing energy […]
