EXAIR is based in Cincinnati, OH and it is where we design and manufacture our products. Since we are the manufacturer, we can design and build custom product when your application demands particular features. Vortex Tubes are the foundation of our cooling products and can be customized to suit your needs in many ways…
The EXAIR Vortex Tube uses compressed air to generate a cold air stream at one end and a hot air stream at the other end. This phenomenon in physics is also known as the Ranque-Hilsch tube. It can generate very cold or very hot air without any moving parts, motors, or Freon. Thus; making it low cost, reliable, and maintenance free. The EXAIR Vortex Tube can generate
- Air temperatures from -50 to +260 deg. F (-46 to +127 deg. C).
- Flow rates from 1 to 150 SCFM (28 to 4,248 SLPM)
- Refrigeration up to 10,200 BTU/hr (2,570 Kcal/hr)
With a wide range of cooling and heating applications, the EXAIR Vortex Tubes can be an ideal product for you. They are used for cooling electronics, CCTV cameras, and soldered parts. They are also useful for setting hot melts, gas sampling, and environmental chambers. With its very compact and versatile design, it can be mounted in tight places to apply heated or cold air to your process. The Vortex Tubes are used for improving process times in cooling, protecting equipment, or setting specific temperature requirements. If you need a Vortex Tube to be more specific to your application, EXAIR can manufacture a proprietary product in the following ways:
Preset Vortex Tubes – the standard Vortex Tube has a screw on the hot end to adjust the cold and hot air temperatures. To make the Vortex Tube tamper-resistant, EXAIR can replace the screw with a preset hot valve. If you can supply the temperature and flow requirements for your application, EXAIR can determine the correct diameter hole to give you a consistent temperature and flow from the Vortex Tube.
Materials – The standard Vortex Tubes has a maximum temperature rating of 125 deg. F (52 deg. C). For elevated ambient temperature, we offer a brass generator which will increase the temperature rating to 200 deg. F (93 deg. C). If other materials are needed for food, pharmaceutical, or chemical exposure, we can also offer stainless steel for the hot plug, cold cap, and generator. I have seen Vortex Tubes made entirely from 316SS and even one made with a brass body. There are EXAIR Vortex Tubes with special material o-rings and hot valves or with customized muffler assemblies.
Fittings – Our standard units have threaded connections on the Vortex Tube to connect fittings and tubing. In certain applications to improve mounting and assembly, special fittings may be required for ease of installation. EXAIR can attach or modify these parts to the Vortex Tube to meet your requirements.
At EXAIR, we pride ourselves with excellent customer service and quality products. To take this one step further, we offer specials to accommodate your applications. As a manufacturer of the Vortex Tubes, we can work with our customers to generate a custom product with high quality, fast delivery, and a competitive price. So, if you do need a special Vortex Tube to give you a specific temperature, ease of mounting, or a proprietary product for your OEM design, you can discuss your requirements with an Application Engineer. We will be happy to help you.
