Questions and answers on vortex coolers and vortex tubes:
- How does a vortex tube work?Read the full answer
A vortex tube converts compressed air into two air streams - one hot and one cold. Compressed air enters the vortex tube and is sprayed tangentially into the vortex chamber. The compressed air spins at high speed, up to 1,000,000 RPM, creating a vortex of air. Some of the air ...
- How does hot compressed air affect a Vortex Tube?Read the full answer
A Vortex Tube produces a temperature decrease in the cold outlet and a temperature increase in the warm outlet relative to the supply air temperature. If the inlet temperature increases, the temperature of both the cold and the hot air stream will increase correspondingly.
- How do I know which "Cold Fraction" value my Vortex tube is set to?Read the full answer
There are several ways to determine what Cold Fraction (ratio of cold to warm airflow) your Vortex tube is set to. One way is to use the performance chart in the EXAIR catalogue or on our website, which shows the temperature rise and fall at different pressures and supply air temperatures. Measure the temperature ...
- What is the difference between a Vortex tube and other cold air products like Cold Gun?Read the full answer
Vortex tubes are the basic component of all EXAIR products that generate cold air flow. It is available in three different sizes and covers a wide range of cooling capacities. All models have an adjustable valve at the hot end, which makes it possible to regulate the distribution between hot and cold...
