Seems like the term vortex is being use for everything from vortex engines and now to polar vortex. Throughout EXAIR’s existence, it has had a product called a Vortex Tube and it is also associated with very cold air. It is truly a vortex and has been around since 1929.
A Vortex Tube is used to generate cold air using compressed normally 80-100 PSIG. It is introduced tangentially into a spin chamber and spins at up to 1,000,000 RPM. This air stream revolves toward the opposite end where some escapes through a control valve (used to adjust the temperature and flow of cold air). The remaining air, still spinning, is forced back through the center of the outer vortex. The inner stream gives off kinetic energy in the form of heat (released out the control valve) to the outer vortex and exits the vortex tube as cold air. See demo [click here]. The refrigerated air produced is used for spot cooling where conventional A/C is not practical or feasible to install.
Over the years, EXAIR has developed several products using the vortex.
- Cold Gun – spot cooling cutting tools
- Cabinet Cooler – cooling control panel
- Adjustable Spot Cooler – when precise variable temperatures are needed.
- Mini Cooler – cooling small parts where heat is a problem
- Component Cooler – for a safe clean way to test electronic components
If you have an application that requires cooling, feel welcomed to call us and ask to speak with one of our engineers.
