What is Cross Flow cooling tower?
A Cross Flow Cooling Tower is a type of cooling tower where the air flows horizontally across the falling water. It is designed so that air and water cross paths at a 90-degree angle, hence the name “cross flow.”
How It Works:
- Hot water from a system (like an industrial process or HVAC system) is distributed at the top of the tower and allowed to fall downward over fill media (a surface that increases water-air contact).
- Ambient air is drawn in from the sides of the tower (horizontally) and flows across the falling water.
- As air passes through the falling water, it absorbs heat through evaporative cooling.
- The cooled water collects at the bottom (in a basin) and is pumped back into the system.
Key Characteristics:
| Feature | Description |
| Air Flow Direction | Horizontal |
| Water Flow Direction | Vertical (gravity-fed) |
| Fan Location | Typically on top (induced draft) |
| Water Distribution | Gravity-fed hot water basins with nozzles |
| Maintenance | Easier, since components are more accessible |
Advantages:
- Energy efficient: Gravity helps in water distribution (no need for pressurized nozzles).
- Low maintenance: Easier access to internal components.
- Quieter operation: Fans can run slower, reducing noise.
