EXAIR Vortex Tubes Reduce Cooling Cycle Time

In a recent phone call with an end user of EXAIR products, we discussed an automotive application within a robotic welding cell.  In this application a series of Fanuc robot arms orient front and rear doors for welding.  After the welds are complete the pre-EXAIR cooling cycle time was more than desired, so Vortex Tube options were explored.

The target cycle time for cooling each weld was 1.5 seconds.  In order to do so, the application needed to be able to quickly produce cold air flow, and required the solution to be lightweight (as to not place excessive torque strain on the robot) and portable within the work cell.

What we found was that the large EXAIR Vortex Tubes would have enough cooling capacity to remove the heat from the welds in the proposed time, but testing needed to be done to confirm.  So, medium sized Vortex Tubes were chosen to prove the concept of vortex-based cooling.

To test the concept, a medium sized Vortex Tube was installed into the application.

After positive results from the testing, (3) model 3299 EXAIR Vortex Tubes were installed into the application.  With the installation of these Vortex Tubes the cycle time was brought within spec and the operations increased throughput.

If you have an application in need of instantaneous cold air, contact an EXAIR Application Engineer to discuss our Vortex Tubes.
