The Most Intelligent Water-Recycling Approach at Kavir Steel Aran & Bidgol
Hybrid and Adiabatic Water-Cooling Systems Introduced for the First Time in Iran

The steelmaking project at Kavir Steel, through the deployment of modern technologies and advanced equipment, is establishing an innovative industrial water-supply method that minimizes water consumption in process-cooling and recycling operations. This technology—featuring adiabatic coolers used for the first time in Iran’s steel industry—marks a significant step forward in the company’s ongoing commitment to social responsibility, particularly in safeguarding vital resources such as water.

This advanced technology utilizes a combination of dry and evaporative cooling within a closed-loop system. Unlike open systems, where water used for cooling exits the cycle after heat exchange, closed-circuit cooling continuously recirculates water within a controlled loop. This configuration drastically reduces water losses and significantly lowers overall consumption.

Adiabatic coolers are engineered to operate in fully dry mode during most of the year, requiring no water at all. During periods of elevated ambient temperature—such as in summer—the system intelligently switches to adiabatic mode, pre-cooling the incoming air by applying a minimal, finely controlled water spray or mist. This reduces the air temperature entering the coils, enabling high-efficiency cooling with exceptionally low energy usage.

The advantages of this system include reduced water consumption, decreased maintenance costs, extended equipment lifespan, and achieving precise target temperatures. Because cooling occurs only to the required level, excessive energy use for unnecessary over-cooling is avoided—an efficiency that traditional cooling methods are unable to provide due to their limited control.
