Cross Flow Cooling Tower

Cross Flow Cooling Tower

Cross flow cooling tower is an induced draft cooling tower that can cool water. Cross Flow Cooling Towers are a type of heat exchange system used in various industrial processes and HVAC (heating, ventilation, and air conditioning) systems to remove excess heat from the surroundings. These towers work on the principle of evaporative cooling, utilizing water and air to transfer heat from a process or a system.Cross flow cooling tower working: The water flows vertically from the top of the tower, and the air flows horizontally through the filler. The air flow is orthogonal to the water flow in the cooling tower.


Compact Design: Cross Flow Cooling Towers have a more compact design compared to other types of cooling towers, making them suitable for installations with limited space or height constraints. Their vertical structure allows for efficient use of space.

Energy Efficiency: These cooling towers typically consume less power due to their design and operation. The water distribution system and air movement mechanisms result in lower energy requirements, leading to reduced operational costs.

Effective Water Distribution: The fill material inside Cross Flow Cooling Towers ensures even water distribution, maximizing the surface area available for heat exchange between water and air. This helps in achieving better cooling efficiency.

Lower Noise Levels: Cross Flow Cooling Towers tend to produce less noise during operation compared to other types, which is advantageous when the cooling towers are located near residential areas or noise-sensitive environments.

Easy Maintenance: The design simplicity of Cross Flow Cooling Towers makes them easier to maintain and clean. Access to internal components and fill material is typically more straightforward, simplifying maintenance tasks.

Handling Varying Flow Rates: These cooling towers can handle varying water flow rates effectively, making them versatile and adaptable to changing process requirements or external conditions.

Good Water Quality: The water exposed to air in the cooling process is less likely to get contaminated with debris, dust, or other impurities. This can help maintain better water quality and reduce the need for frequent water treatment.

Improved Water Conservation: Cross Flow Cooling Towers can be designed with features like drift eliminators, which help minimize water loss due to evaporation. This contributes to water conservation efforts and reduces the overall water consumption of the cooling system.

Suitable for Warm Climates: Cross Flow Cooling Towers are well-suited for warm climates because of their effective cooling capacity even when the surrounding air temperatures are relatively high.

Scalability: These cooling towers are available in various sizes and capacities, allowing them to be scaled to meet the specific cooling requirements of different industrial processes or HVAC systems.

The cooling tower is often used in residential areas with strict noise requirements, and cross flow induced draft cooling tower is a cooling circulating tower used more frequently in the air conditioning industry.

Working principle

The cross-flow cooling tower operates with the airflow perpendicular to the water flow. The air is in contact with the PVC filler, the water flows through the PVC filler by gravity, and then the fan exhausts the moist air from the cooling tower to the atmosphere. The heat dissipation material is close to the water basin, which has the advantage of reducing water droplet noise. Cross-flow method is commonly used in square cooling tower. However, there are more fastening steel plates in the structure, and the cost is higher than that of circular cooling tower.

Cross Flow and Counter Flow Cooling Tower

The difference between cross flow and counter flow cooling tower is that the structure, size, water spray density, filling height and the design flexibility.

Technical Comparison Between Counter Flow Cooling Tower And Cross flow Cooling Tower
ProjectCounter Flow Cooling TowerCross Flow Cooling Tower
Tower HeightDue to the height of the air inlet and the horizontal arrangement of the water eliminator,the total height of the counter flow tower is high and the volume is large.Because the height of packing is close to the tower height and the water
eliminator does not occupy the height, the total height of cross flow tower is low and the volume is small.
Water Distribution SystemThe counter flow tower adopts the nozzle to distribute water, which has higher requirements on the pressure head and the nozzle is easy to be blocked.The cross flow tower adopts the water distribution system of gravity falling naturally, so the water dispersion hole is not easy to be blocked, and the water distribution is uniform, which improves the packing performance to the maximum.
OverhaulThe whole body of counter flow tower is a closed structure, so it should be shut down during equipment maintenance or routine maintenance.The cross flow tower body is equipped with an access door, and there is room for maintenance inside the tower, so that the equipment can be overhauled and maintained without shutdown.
Wind ResistanceDue to the reverse flow of water and gas in the counter flow tower and the obstruction of water distribution to the air flow, the wind resistance is high and the power consumption of the motor is large.The cross flow tower is lower than the counter flow tower, and the high air inlet means the high packing, so the air inlet speed is low and the motor power consumption is low.
NoiseThere is a large distance between the packing of counter flow tower and the lower water tank. After the water falls from the packing, there is a loud noise.A small part of the lower part of the packing of the cross flow tower is submerged in the water, so that the water flows directly into the lower water tank after passing through the packing surface, and the noise is very low.
Water LossBecause the fan of counter flow tower is located directly above the packing and the distance is close, the water drift is large. In addition, the splash loss of the water in the lower tank is very large, and it is easy to form water mist around the cooling tower, which is easy to cause the reproduction of Legionella.The cross flow tower fan is located in the center of the cooling tower, and the packing is located on both sides, so the water drift is very small, which is an environmental protection cross flow type cooling tower.
ModularizationThe unit of counter flow tower is
supplied with air from all sides, and the air inlet surface is reduced after module combination, which affects the air inlet volume.The power consumption of the motor will increase.
The cross flow cooling tower design is specially for modularization,
with air inlet from both sides of the unit. After the combination of the modules, the air inlet has no change, and the power consumption of the motor remains unchanged.

Cross Flow Cooling Tower Design

  1. Induced draft cross flow cooling tower features: Energy-saving, low water pressure, small wind resistance, low-speed motor, no dripping noise and wind noise, and convenient maintenance of filler and water distribution system.

  2. According to the shape of the building, the foundation can be built randomly, and multiple cell cooling towers can be started according to the water temperature required.

Cross Flow Cooling Tower Working

As a major cooling tower inc, our cross flow cooling tower casing is made by machine. It makes the casing have a smooth surface and good quantity.

The motor driver we using belt reducer with low noise characteristic. The belt is very stronger, clients no need to replace it frequently. If you choose a cross-flow closed circular cooling tower, we will use a cooling tower direct drive motor.

The fresh air comes from the cooling tower tow side continuous, the fresh air will take water heat continuously.
