Cooling system energy saving system

Overview
battenfeld-cincinnati presents the Green Pipe concept: a downstream cooling and drying approach designed to reduce energy, water and material use on extrusion lines. The concept combines targeted internal air cooling, an energy-efficient dryer and line energy monitoring to optimize each downstream component for pipe production.

Green Pipe downstream concept

• Cooling-section energy consumption can be reduced by up to ~50%
• Cooling water consumption per hour can be lowered by up to ~90%
• Free Cooling potential can increase by up to 50%

Green Pipe components
helix II VSI-T pipe die with Efficient Air Cooling EAC

• Internal counterflow ambient-air cooling: ambient air flows through the pipe against extrusion direction to provide uniform internal cooling
• Depending on application, cooling-section length can be reduced by 30%–50%
• Possible integration into existing extrusion lines after consultation
• Most existing battenfeld-cincinnati pipe heads are retrofit-capable

EAC drying system (Labotek)

• Co-developed with battenfeld-cincinnati for compatibility with helix II VSI-T dies
• Energy-efficient combination dryer design
• Two separate drying zones to optimize throughput and energy use

Energy monitoring & modular approach

• Line energy monitoring identifies optimization potential across every component
• Modular Green Pipe approach enables targeted retrofits to reduce material, energy and water consumption
