Ring Blades for Cooling

The use of Ring Blades for cooling is widespread across a variety of manufacturing processes. They are a suitable choice of compressed air cooling system for any product that can feasibly pass through the blade, for example, extrusions. These blades can be made with internal diameters of up to 11" (279 mm) so this makes them suitable for cooling even quite large extrusions or product conveyor lines.

The big advantage of ring blades is that they provide an even, 360 degrees of air cooling so the whole product line sees a rapid air current. This can be particularly important in the cooling of hot extrusions where uneven cooling can cause product defects.

The high impact of the air will also serve as a fluid/debris blow off systems allowing the target to be cleaned and cooled at the same time.

Maintenance and reliability

When compared to blower systems enhanced compressed air cooling systems are very easy to maintain. Whether the system is comprised of air nozzles, air amplifiers, air jets or air knives there are no moving parts involved and no external power is required. This means that there is virtually nothing to go wrong with the blow off system. Similarly, vortex tube powered coolers have no external power source or moving parts are so are equally reliable and maintenance free.

The simplicity of these systems means they can be deployed in areas that would preclude the deployment of powered blowers. In dirty, wet or humid areas of the production facility any powered equipment requires often costly protection to prevent it breaking down. This may involve water proofing or additional filtration / dust protection. Compressed air systems require none of this and so, in such environments, they are intrinsically more reliable.
