1. Open cooling towers operate with the cooled medium exposed to sunlight, making them prone to algae and salt crystal formation, thus affecting system performance. Dry operation is not possible when the fluid is volatile, toxic, or hot; open cooling tower operation poses safety hazards.
2. With the cooled medium circulating in an open system, scaling easily forms on the system pipes and heat exchangers of the cooled equipment, reducing heat exchange efficiency and increasing operating costs. In contrast, the cooled medium flows within closed pipes, not in contact with outside air. Heat is exchanged between the heat exchanger tubes and external air, spray water, etc., to achieve cooling.
3. Therefore, the cooled medium is not contaminated, evaporated, or concentrated, eliminating the need for water or chemical replenishment. This ensures the performance and lifespan of connected equipment and simplifies daily management. Frequent downtime for maintenance is unnecessary, ensuring stable and safe operation, reducing the failure rate of connected equipment, and making it suitable for systems requiring continuous operation.
4. Because the cooled medium is not exposed to sunlight and does not come into contact with air, it will not produce algae or salt crystals, thus eliminating the need for algae and salt removal and ensuring high-performance system operation.
5. It can operate in a dry state, preventing the growth of various bacteria, making it particularly suitable for applications requiring air purification and frequently used in water-scarce and arid regions. When the fluid is a volatile, toxic, or alkaline solution, the closed-loop circulation system prevents environmental pollution, making it widely applicable to systems with strict fluid requirements.
6. The cooled medium flows within a closed pipeline, typically softened water. Scale will not form in the system pipelines or the heat exchangers of the cooled equipment, resulting in high operating efficiency for the cooled equipment and energy savings for the entire system.
