Mini Cooler Improves Custom Cutlery Production

Vortex Tubes use compressed air to create a stream of cold air and a stream of hot air. As the compressed air enters the unit, it travels through a spin chamber which spins the air at speeds up to 1,000,000 RPM producing temperatures ranging from -50°F to +260°F and providing cooling up to 10,200 Btu/hr. With no maintenance requited and no moving parts, they have become quite popular in large and small scale cooling applications in place of more conventional methods of cooling.

How an EXAIR Vortex Tube Works

EXAIR has incorporated this technology into several different products like our Cabinet Cooler Systems used to cool electrical panels and our Cold Guns commonly used to replace messy mist systems in tool cooling, milling and machining operations. For smaller scale processes we offer our Mini Cooler System which provides a 50°F temperature drop from the compressed air supply temperature and 550 Btu/hr. of cooling capacity.

I recently worked with a small, custom knife manufacturer who was looking for a way to keep his tooling cool during production. As the blades are made, he uses a small rotary die tool to shape and sharpen the blade. He also makes his own handles out of materials like wood, ceramics or other metals, which get etched with a custom design into the surface. The heat generated during theses processes, causes the tooling to either bend or break completely, resulting in damage to the knife blade and burns or breaks in the wood and ceramic handles. After looking at our spot cooling products online, he familiarized himself with the Vortex Tube technology but with only 12.9 SCFM of air available, he was unsure what product would best fit his application.

With the limited amount of air available, the Model # 3808 Mini Cooler System was the perfect solution. The Mini Cooler uses only 8 SCFM @ 100 PSIG, falling well within the capacity of his current compressor. The integral magnetic base would ensure an easy installation and with the included flexible hose, he could direct the cold air to the needed area.

The Mini Cooler is ideal for small tool and part cooling applications.
