Blown Film Coolers (BFC)


Berg BFCs are available in standard models to meet the requirements of most blown film applications, and can be customized as required.
  • – Available in left and right-hand configurations
  • – Outlet air temperature can be as low as 5°C (41°F)
  • – Rugged industrial design with few moving parts
  • – Enables exceptional blown film product quality
  • – Limited maintenance required
  • – Energy efficient coil design
  • – Accepts both glycol and chilled water
  • – Rugged Industrial Quality
Berg BFCs are factory built and tested. Each BFC is assembled, insulated, piped, and wired on a painted structural steel frame. Pressure blowers can be inverter duty or have variable frequency drives allowing complete pressure and airflow control. Blowers are selected based on industry standards or specific process airflow and pressure requirements. The resulting system is a single, integrated package, ready for air line connections.

Maintain Precise Temperature Control
In applications where air temperature is crucial to sustaining a stable bubble and a high-quality product, Berg BFCs can be equipped with precision control valves that will closely regulate the cooling water/glycol temperature.

Custom designed by our experts and yours
No one knows your systems like your own systems people. That’s why we involve them in the design of your Berg Blown Film Cooling system, ensuring your custom engineered system precisely meets all your requirements and unique challenges.

Completely Controlled Air Quality
