How to Select an Industrial Chiller for Film Extrusion

Why Chiller is Essential for Film Extrusion?

Temperature control is critical during film extrusion.

Without stable cooling, problems will occur:

• Uneven thickness
• Wrinkles & bubbles
• Poor transparency

Chiller ensures stable temperature, improving quality and output

Key Cooling Points

• Chill Roll,Directly affects film quality
• Die Head,Maintains stable extrusion temperature

How to Size the Chiller

General guideline:

1 ton output ≈ 3–5 HP chiller

100kg/h → 10–15HP

300kg/h → 30–50HP

500kg/h+ → 60–100HP

Factors to consider:

• Output (kg/h)
• Material (PE / PVC / PET)
• Ambient temperature

Recommended Water Temperature

Leaving water temperature: 7–15°C

The more stable the temperature:

• Better surface
• Uniform thickness

In film extrusion, the cooling system directly affects product quality and productivity. A properly selected chiller improves stability and output.
