Cooling Tower Cleaning Frequency and Why Timing Matters

Cooling tower retrofit solutions to reduce evaporation loss in India

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 […]

6 Methods For Improving Indoor Air Quality (IAQ)

Technician checking and maintaining an air conditioning unit.

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 

Close-up of wiring inside a centrifugal fan

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

Large industrial cooling tower with green pipelines and external ladder setup under a clear blue sky.

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 […]

How High Static Pressure Affects Your HVAC System

Technician measuring HVAC static pressure using gauges with text overlay about how high static pressure affects HVAC systems.

Airflow is the performance key in any HVAC system. If air isn’t moving well through ducts, filters, and equipment, the system can’t provide comfort, and it uses more energy than it needs to. One of the largest performance robbers is high static pressure. Knowing what static pressure is, why it is important, and how to […]
