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 […]
Top 10 Benefits of a Cooling Tower in the Manufacturing Industry
Table of Contents In manufacturing, every process that generates heat — from compressors to moulding machines needs efficient cooling to maintain productivity and protect equipment. That’s where cooling towers make all the difference. At Aad Tech, a part of Melfrank, we’ve worked closely with manufacturing facilities across India to design, install, and retrofit cooling towers […]
Air Handling Unit (AHU) for Pharmaceuticals: A Practical Approach to Retrofitting
Table of Contents In pharmaceutical facilities, air quality directly affects product integrity and compliance. The Air Handling Unit (AHU) plays a central role in maintaining controlled temperature, humidity, and cleanliness. At Aad Tech, we focus on retrofitting AHUs upgrading existing systems with modern, efficient components. This helps facilities improve performance and reduce energy use without […]
6 Methods For Improving Indoor Air Quality (IAQ)
Indoor air quality (IAQ) is essential in ensuring a healthy, comfortable, and productive indoor climate for offices, hospitals, industrial buildings, or commercial settings. Poor indoor air quality not only contributes to the deterioration of employee health and well-being but also to reduced productivity, equipment lifespan, and industry compliance. To address this challenge, most businesses are […]
What Happens When A Centrifugal Fan Is Wired Backwards
Centrifugal fans are a key part of industrial and commercial HVAC operations, providing effective airflow for heating, ventilation, and cooling. Yet improper installation or wiring mistakes can cause substantial performance issues. One of the most basic yet overlooked issues is a centrifugal fan being wired in reverse. Learning what the impact of this error is, […]
Cooling Tower Retrofit For Water & Energy Savings
In industrial facilities, large commercial structures, and computer data centers, cooling towers are integral components of air-conditioning systems to dissipate heat from water-cooled machinery. However, aging cooling towers become inefficient, wasting enormous amounts of water and energy while performing below optimal efficiency. Rather than costly full overhauls, a cooling tower retrofit is an extremely efficient […]
