Dry Coolers
Powerful Cooling, Zero Water Waste
A Dry Cooler, also called an Air-Cooled Fluid Cooler, is a high-efficiency cooling system that uses ambient air to remove heat from process fluids—without consuming water. It is Efficient, reliable, and low-maintenance heat rejection solutions for industrial and commercial applications.
WORKING PRINCIPLE
Dry cooler is a heat rejection equipment where the excess process heat is rejected to the atmosphere. It works on the principle of convection and conduction to dissipate heat from process fluid to air; the process fluid passes through the tubes and air stream is passed over the tubes to carry away the heat; air streams are created by the fans mounted on the unit.
Key Benefits of Dry Coolers
- Water Saving – Operates on dry cooling principle, drastically reducing water usage compared to conventional cooling towers.
- Eco-Friendly – No need for chemical dosing or water treatment, minimizing environmental impact.
- Low Operating Cost – Saves on both electricity and water bills with high-efficiency fans and low maintenance requirements.
- High Reliability – Robust design with fewer moving parts ensures consistent performance and extended service life.
- Hygienic & Safe – No stagnant water or drift eliminates the risk of Legionella and other waterborne bacteria.
- All-Weather Performance – Delivers reliable cooling throughout the year; optional adiabatic system boosts efficiency during peak summer.
- Versatile Applications – Ideal for HVAC systems, industrial processes, data centers, refrigeration plants, and engine cooling.
- Easy Installation – Compact, modular, and plug-and-play design reduces civil work and enables quick commissioning.
