Overview PVC Film Fill for Cooling Tower

Here’s a clear, professional overview of PVC film fill for cooling towers, suitable for product pages, RFQs, and technical reference.

PVC Film Fill for Cooling Tower

1. What Is PVC Film Fill?

PVC film fill is a high-efficiency cooling tower fill made from cross-corrugated PVC sheets.

It works by forming a thin water film on the sheet surface, maximizing air–water contact area and improving heat transfer.

It is the most commonly used fill type in modern HVAC and industrial cooling towers.

2. Key Design Features

* Cross-fluted (corrugated) PVC sheets

* Uniform water distribution

* High surface area per m³

* Low airflow resistance

* Factory-bonded into rigid fill blocks

Common corrugation angles: 30° × 60°

5. Typical Applications

* HVAC cooling towers

* Water-cooled chiller systems

* Office buildings & malls

* Hospitals

* Data centers

* Power plant auxiliary cooling

6. Performance Benefits

✔ Higher cooling efficiency

✔ Lower condenser water temperature

✔ Reduced chiller energy consumption

✔ Stable approach temperature

✔ Long service life (5–10 years)

Each 1°C reduction in approach temperature can improve chiller efficiency by **2–3%**.

7. OEM-Equivalent PVC Film Fill

PVC film fill can be manufactured as equivalents to:

* Marley MX75 / MX80 / MX85

* EVAPCO film fill

* BAC film fill

Aftermarket PVC film fill can match OEM performance at a lower cost when properly designed.

8. Installation & Maintenance Tips

* Install in block form, not loose sheets

* Ensure uniform spray nozzle coverage

* Avoid water temperature above 60°C

* Maintain proper water treatment

* Periodic low-pressure cleaning recommended
