PVC Fill

PVC Cooling Tower Fill Media

Overview

HACST® manufactures a complete range of PVC, CPVC, and PP cooling tower fill media designed for high thermal performance, durability, and compatibility with all major cooling tower brands, including Marley, BAC, Liangchi, Kingsun, Brentwood, Kuken, Hamon, and others.

Cooling tower fill is the core heat-exchange component responsible for forming water films or droplets, increasing the contact area with air, and enabling efficient evaporative cooling. High-quality fill media directly improves cooling capacity and reduces energy consumption.

Role in Cooling Towers

• Heat Transfer Enhancement: Corrugated or grid structures create large surface areas for evaporation.
• Improved Water Distribution: Develops uniform water films or droplets for balanced air–water contact.
• Maximized Cooling Efficiency: Determines up to 70–80% of overall cooling tower performance.
• Supports Crossflow & Counterflow Designs: Suitable for industrial, HVAC, and high-load cooling environments.

Materials

HACST uses high-grade polymers to ensure long service life and stable cooling performance.

Types of Cooling Tower Fill

A. Film Fill (High-Efficiency Thin Film Type)

Designed for clean water applications requiring maximum thermal performance.

• Marley Type (F-001–F-010): 19mm spacing, 610–1520mm width.
• BAC Type: Optimized corrugated sheets for high cooling efficiency.
• Liangchi Type (F-011–F-012): 20mm sheet spacing.
• Kuken Type (F-013–F-014): 15/20mm spacing for Japanese cooling towers.
• Kingsun Type (F-017–F-019): 12–19mm spacing, 300–610mm width.
• Brentwood Type (F-020–F-022): Includes S-type & turbidity-resistant designs.
• Hamon Type (F-023–F-024): 305–610mm width for European cooling systems.

B. Special Structured Film Fill

• S-Type Fill (F-027): High turbulence and mixing effect.
• Spindle Fill (F-026): Suitable for crossflow towers.
• Round Cooling Tower Fill (F-028): 650–810mm diameter.

C. Splash Fill (For Poor Water Quality)

• PP Grid Fill (F-029): Strong chemical resistance and anti-fouling ability.
• PP Trickle Fill: Suitable for high-temperature or polluted water conditions.

Advantages of HACST® Fill Media

• Hydrophilic surface improves water distribution by 15–20%.
• High structural strength from vacuum forming and hydraulic compression.
• Excellent UV resistance, anti-aging and long lifespan.
• Easy installation, cutting, and replacement for all major brands.
• PP and CPVC options available for high-temperature and corrosive environments.

Available Specifications

• Length: 400–1800mm (customizable)
• Width: 225–1520mm
• Sheet Spacing: 12 / 15 / 16 / 18 / 19 / 20 / 33 / 61 mm
• Thickness: 0.3–1.0 mm
• Colors: Black, grey, blue, transparent

Applications

Cooling tower fill media is widely used in:

• HVAC & commercial cooling
• Petrochemical plants
• Power stations
• Steel & metallurgy
• Food processing (chicken, meat, seafood)
• Plastic extrusion & injection cooling
• Mining & coal washing
• Industrial refrigeration systems
• Evaporative condensers
• Data centers

Installation Guide

1. Remove old fill and clean internal tower structure.
2. Check beam supports and spacing before installation.
3. Install blocks layer-by-layer in correct airflow direction.
4. Fix sheets using PVC welding or nylon tie rods.
5. Run water distribution test to confirm uniform flow.
