Induced Draft Cooling Tower Parts

Here’s a list of the main parts of an induced draft cooling tower and their functions:

1. Induced Draft Cooling Tower Parts Fan Assembly

Location: Top of the tower

Function: Pulls (induces) air through the tower and discharges it upward

Type: Axial fan (commonly used)

Includes: Fan blades, fan hub, fan guard, fan motor

2. Induced Draft Cooling Tower Parts Fan Motor

Drives the fan

Can be direct drive or gear/belt driven

Weatherproof and suitable for high humidity

Here3. Induced Draft Cooling Tower Parts Gearbox or Drive System (if not direct drive)

Transfers power from motor to fan

Maintains correct fan speed

Types: Gear reducer, belt drive

4. Induced Draft Cooling Tower Parts Fill (Heat Exchange Media)

Increases water surface area for better cooling

Types: Film fill or splash fill

5. Induced Draft Cooling Tower Parts Water Distribution System

Distributes hot water evenly over fill

Components: Spray nozzles, hot water basins, or spray headers

6. Induced Draft Cooling Tower Parts Drift Eliminators

Capture water droplets entrained in air stream

Prevents water loss and drift emissions

7. Induced Draft Cooling Tower Parts Air Inlet Louvers

Allow air to enter the tower

Prevent splash-out, reduce sunlight, and block debris

8. Induced Draft Cooling Tower Parts Cold Water Basin

Collects cooled water after heat exchange

Has outlet connection, make-up valve, and drain

9. Induced Draft Cooling Tower Parts Casing / Tower Structure

Encloses all components

Made from FRP, galvanized steel, or concrete

10. Induced Draft Cooling Tower Parts Accessories

Vibration switch: Protects against mechanical failure

Temperature sensors: Monitor inlet/outlet water temps

Level control valves: Maintain proper basin water level

Ladders & platforms: For maintenance access
