I recently had the pleasure of discussing a cooling application with a customer. The caller was familiar with our Cabinet Cooler Systems, and wanted to incorporate the same technology into a spot cooling application. Problem was, he wasn’t sure about exactly how much cold air flow, and at what temperature, would suit his needs best…this was on a brand new mold (for plastic parts) that had just arrived. His idea was to order a few different Vortex Tubes, and experiment with them.
I agreed that trying a few different Vortex Tube models would be a quick and easy way to find a solution, but I had a quicker and easier way: the Model 3930 Medium Vortex Tube Cooling Kit. This gave him all the Generators that fit the Medium Vortex Tube, allowing him to make any medium Vortex Tube model he desired. He would also be able to adjust the Cold Fraction to get the most effective temperature drop as well.
With the Vortex Tube in place, it was very easy to configure the optimal cooling…as he decreased the Cold Fraction (to get colder air) he replaced the Generator (to get higher air flow.) His application (cooling molded plastic parts) was satisfied with a Model 3225, set to a 70% Cold Fraction…this gave him 17.5 SCFM of cold air flow, at temperature of around 0F (a 71F drop from their compressed air supply temperature, which is around 70F.)
Is an EXAIR Cooling Kit right for your heat removal application? If you’d like to find out, give me a call.
