Why Your Cooling Tower Is Underperforming: 7 Root Causes
In industrial refrigeration and HVAC systems, the cooling tower is often the most overlooked component (until the chiller trips on high-pressure alarms). The financial penalty of neglect is immediate and severe: a mere 1°C increase in cooling water temperature can spike a chiller’s energy consumption by 2–3%. To master cooling tower troubleshooting, one must look […]
Cooling Tower Efficiency in Indian Summers: Why Standard Ratings Fail
It is a familiar dread for facility managers across India. As May approaches and temperatures in the Gujarat chemical belts push 45°C, or the humidity in Chennai crosses 80%, the plant’s cooling tower (the very one the catalogue promised would deliver 500 TR) suddenly cannot keep up. The result? Escalating energy bills, reduced production output, […]
High Static Pressure Fans for Cooling Towers: EC vs Traditional, Avoid Specification Pitfalls
In the current industrial HVAC landscape, the shift toward Electronically Commutated (EC) fans is often framed as a universal upgrade. Their integrated electronics and high part-load efficiency make them an attractive proposition for modernising cooling tower performance. But there is a static pressure wall where the elegance of EC technology meets the physics of high-resistance […]
Stop Wasting Energy: The Approach Temperature Your Cooling Tower is Hiding
For facility managers across India, from the humid tech parks of Bangalore to the industrial belts of Chennai, efficiency is often chased through expensive chiller upgrades or chemical overhauls. Yet, the most critical indicator of your system’s health is usually sitting in plain sight, unmonitored: the Approach Temperature. If you aren’t tracking your approach, you […]
The Silent Profit Killer: Is Your Cooling Tower Approach Bleeding Your Bottom Line?
Cooling tower approach temperature directly dictates how hard your chiller works. A smaller approach means colder water enters the chiller. Such a change reduces the physical pressure the compressor must overcome. When the compressor works less, your electricity bills drop. Specifically, every 1°C decrease in water temperature can improve chiller efficiency by about 3%. In […]
Cooling Tower Retrofits: When Component Replacement Makes Sense and When It Doesn’t
Every cooling tower eventually sends small signals. A new vibration appears. Outlet temperatures creep up. Energy use quietly climbs. At some point, someone asks the real question: Is this just a worn part, or is the system trying to tell us something more? That question sits at the heart of retrofit decisions. Replacing components can […]
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. […]
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 […]
