list of key parts in a Bottle Shape Cooling Tower

detailed list of key parts in a Bottle Shape Cooling Tower, along with their functions:

. Structural Components

Part	Material	Function
Casing (Shell)	Fiberglass (FRP) / Stainless Steel	Protects internal components, provides structural support.
Support Frame	Galvanized Steel	Holds the tower’s weight and resists vibrations.
Base Pan (Sump)	FRP / Polypropylene	Collects cooled water for recirculation.

2. Heat Exchange System

Part	Material	Function
Fill Media	PVC, PP, or HDPE	Increases water-air contact for efficient cooling.
Hot Water Inlet	FRP / Stainless Steel	Distributes hot water to the fill media.
Water Distribution System	PVC/FRP Nozzles	Sprays water evenly over the fill.

3. Airflow & Ventilation

Part	Material	Function
Induced Draft Fan	Aluminum/FRP	Pulls air upward (counterflow design).

Fan Stack	FRP	Directs exhaust air out of the tower.
Air Inlet Louvers	FRP/PVC	Controls air intake, prevents debris entry.

4. Water Conservation & Drift Control

Part	Material	Function
Drift Eliminators	PVC/PP	Prevents water droplets from escaping with air.
Makeup Water Valve	Brass/Stainless Steel	Replenishes lost water due to evaporation/drift.

5. Mechanical & Safety Components

Part	Material	Function
Motor & Gearbox	Cast Iron/Stainless	Powers the fan (often with speed control).
Vibration Switches	Stainless Steel	Shuts down the fan if excessive vibration occurs.
Access Doors	FRP/Aluminum	Allows maintenance access to internal parts.

6. Optional Add-Ons

Part	Material	Function
Chemical Dosing Port	PVC/FRP	For adding water treatment chemicals.

Ice Prevention System	Electric Heaters	Prevents freezing in cold climates.
Noise Reduction Pads	Acoustic Foam	Minimizes operational noise.

Key Differences vs. Square Cooling Tower Parts

• Bottle Shape:
  • Uses counterflow fill media (vertical airflow).
  • Induced draft fan at the top (not at the base).
  • More compact FRP casing (vs. steel in square towers).
• Square Tower:
  • Typically has crossflow fills (horizontal airflow).
  • May use forced draft fans (louder, base-mounted).

Maintenance Checklist for Bottle Shape Towers

1. Monthly: Inspect fill media for clogging.
2. Quarterly: Clean drift eliminators and check fan balance.
3. Annually: Motor servicing and corrosion checks.
