What is Cross Flow Closed Circuit Cooling Tower
Cross flow closed circuit cooling tower is a cooling device that is designed to remove the heat of the process fluid, thereby cooling the process fluid. With tubular exchangers placed in the tower, the whole cooling process is achieved through heat change among cross flow air, spray water & circulating water via tubular exchanger inside. Our cross flow closed cooling tower uses a combination of filler and main surface coil, and its performance is significantly better than that of traditional closed fluid coolers.
Benefits of Cross Flow Closed Circuit Cooling Tower
Energy Efficiency
The cross flow design allows for efficient heat transfer while reducing energy consumption. Separating the air and water streams minimises the reabsorption of moisture and maximises cooling performance.
Space Efficiency
Cross flow closed circuit cooling towers have a compact design, making them suitable for installations with limited space. Their vertical airflow pattern requires less horizontal area, enabling flexibility in industrial plant layouts.
Easy Maintenance
Accessible components, such as the fill media and drift eliminators, simplify cleaning and maintenance tasks. Routine inspections and maintenance can be conducted efficiently, minimising downtime and optimising tower performance.
Environmental Benefits
Cross flow closed circuit cooling towers contribute to water conservation and reduce chemical usage. The efficient separation of air and water streams minimises water wastage, while drift eliminators prevent water droplets from escaping into the atmosphere. By conserving water and reducing chemical usage, cross flow closed circuit cooling towers promote sustainability and environmental responsibility.
Internal circulation: The circulating medium enters the heat exchange coil in two ways after being heated by the heat source heat exchange, and the heat energy is transferred to the external water film through the tube wall through the heat exchange coil, and the water film absorbs heat and converts it into latent heat of vaporization. After the circulating medium is cooled, it is sent to the production heat source.
External circulation: The spray water is sent from the water tank to the spray system, and evenly sprayed to the outside of the pipe to form a water film, and part of it becomes water vapor, which is discharged through the fan, and the unevaporated spray water falls to the water tank and circulates again.
Air circulation: Dry and cold air enters from both sides of the cross-flow closed tower, sweeps horizontally across the coil at high speed, takes away the evaporated water vapor, takes away heat energy, increases the humidity, and is discharged out of the tower by the exhaust fan in the middle chamber.
In a counter flow closed circuit cooling tower, the air flows vertically upward while the water falls. This is possible because of an induced draught fan that is attached to the motor located on top of the tower. Upon the entry of the air, the fan will immediately pull it upward to cross the fill and ultimately leave the tower. The water, on the other hand, falls onto the fill through pressurized pipe-type spray systems near the top of the tower. Another good thing about this tower is that it is compact and fully closed. This eliminates the exposure of the tower's internal components to sunlight and other external variables.
For a cross flow closed circuit cooling tower, water falls down perpendicularly to the direction of the air. This means that the air flows through the fills horizontally, then rising upward to meet the water at a 90-degree angle. This tower uses splash type fillings that are best for water that has higher suspended particles. Unlike counter flow closed circuit cooling towers, cross flow closed circuit cooling tower is designed with accessibility in mind. This tower offers full access to its components, making necessary adjustments and replacements possible and easier. Moreover, this tower distributes water equally, which prevents icing and freezing problems that are common to counter flow cooling towers. Finally, a cross flow closed circuit cooling tower consumes less power.

How to Choose the Right Cross Flow Closed Circuit Cooling Tower
Consider Environmental Conditions
The effectiveness of a cooling tower depends on the wet-bulb temperature of the surrounding air. Ensure the unit can handle the climatic conditions of your location.
Determine Space and Installation Needs
Assess the available space for the tower, including height restrictions if applicable. Decide whether the cooling tower will be placed indoors or outdoors and choose a model that is weather-resistant if needed.
Materials
For long-term durability, consider cooling towers made from materials like stainless steel, galvanized steel, or high-quality fiberglass. Materials should be chosen to minimize maintenance costs and maximize lifespan.
Energy Efficiency
Choose models with energy-efficient motors and fans to reduce operating costs. VFDs can optimize energy use by adjusting fan speed based on load requirements.
Maintenance and Accessibility
Ensure that the cooling tower has accessible components for regular inspection and maintenance. Some models offer self-cleaning features that can reduce maintenance frequency.
Budget and Cost Considerations
Factor in the purchase price, including transportation and installation. Estimate ongoing operational expenses, including energy and water usage.
Maintenance Tips for Cross Flow Closed Circuit Cooling Tower
Regular inspection
The first stage in cooling tower maintenance is to do regular inspections. If the water pump in a cooling tower isn't greased regularly, it might create complications. A well-maintained pump with no back-and-forth resistance will function better and cost less. Check the pump's alignment during lubrication and lubricate the motor bearings and water seal.
Improve the movement of air
Airflow issues are a major cause of cooling towers not performing as effectively as they should and may even cause the system to collapse. If air cannot flow freely through the tower, the fan may malfunction, and the air in the tower may not feel chilly. Scaled or packed tower fill, a fan that isn't properly positioned or well-oiled, clogged filters, or poor water treatment may prevent airflow.
Water Repair
Water treatment is critical to how smoothly and safely a cooling tower operates. Legionella is a dangerous bacterium that thrives in cooling towers. Alternative to treating the water in a cooling tower for Legionella, other approaches may aid it. Biofilms, scaling, and corrosion may occur when the pH is out of balance if biological pollutants are present. These things harm equipment, induce fouling and impair its performance. Treating the water in a cooling tower extends its life and protects humans against Legionella infections.
Tower Tubes Must Be Clean
If air conditioners or chillers are not serviced regularly, the condenser tubes may get clogged, making it difficult for heat to transfer between the tower and the air. Scale, slime, algae, and other muck may accumulate in a condenser tube, limiting its cooling capacity and causing the system to fail. Contaminants may accumulate even if the water in a cooling tower is properly cleaned. Therefore it is critical to clean it regularly.
Scaling and placement
Evaporation of water in cooling towers produces water vapor, which is why Legionella outbreaks are associated with them. The bacteria cause illness when contaminated water comes into contact with mucosal membranes, most notably the lungs. Water evaporates while a tower operates properly, leaving deposits and scaling on the surfaces that transmit the most heat. Limescale development may reduce a tower's effectiveness and cause it to collapse because it serves as an additional barrier or insulator, preventing heat from passing through. If you treat your water properly, descaling should be done yearly.
