A Fiber Reinforced Plastic (FRP) Cooling Tower is a lightweight, corrosion-resistant cooling system widely used in industries and HVAC applications. Here’s a list of its key parts:
1. Structural Components
- FRP Casing – Outer shell made of fiberglass for corrosion resistance.
- Support Frame – Usually made of galvanized steel or FRP for structural stability.
2. Water Distribution System
- Hot Water Inlet Pipe – Entry point for warm water from the process.
- Distribution Nozzles/Spray Headers – Spreads water evenly over the fill media.
- Gravity Distribution Basin (in crossflow towers) – Holds water before it flows over fills.
3. Fill Media (Packing)
- Film Fill/Splash Fill – Increases water-air contact for efficient heat transfer.
- PVC/PP Fill Sheets – Corrosion-resistant material for long life.
4. Air Circulation System
- Fan (Axial/Propeller Type) – Moves air through the tower (forced/induced draft).
- Fan Motor & Drive Assembly – Powers the fan (belt-driven or direct-driven).
- Fan Stack (FRP) – Directs exhaust air upwards to prevent recirculation.
- Drift Eliminators – Reduces water droplet carryover into the exhaust air.
5. Water Collection & Recirculation
- Cold Water Basin – Collects cooled water at the bottom.
- Strainer/Sump Screen – Filters debris to prevent clogging.
- Makeup Water Valve – Replenishes lost water due to evaporation/drift.
- Overflow & Drain Connections – Maintains water level and allows cleaning.
6. Louvers
- FRP/ PVC Louvers – Directs airflow and prevents sunlight/algae growth (in crossflow towers).
7. Accessories & Safety Features
- Vibration Switches – Protects the fan motor from damage.
- Inspection Doors – Allows maintenance access.
- Float Valve – Automatically controls water level.
- Anti-Icing System (for cold climates) – Prevents freezing.
Advantages of FRP Cooling Towers
◉ Corrosion-resistant (ideal for harsh environments).
◉ Lightweight & durable (easy installation, long lifespan).
◉ Low maintenance compared to metal towers.
