Solution Overview

Problem

Existing fluid channels for container treatment systems are expensive and complex due to their metal construction, making them costly to produce and difficult to manufacture in curved forms that follow the transport route of containers.

Innovation Solution

The fluid channel is manufactured using an additive manufacturing process, allowing for cost-effective production and improved cooling performance by designing the outlet openings as nozzles with specific flow directions that can vary along the channel, optimizing the cooling of container bottoms without the need for additional elements or complex construction.
