How does a vortex tube work?
Instantly generate hot and cold air from compressed air, without electricity or refrigerants.
Step 1: Compressed air injection
The compressed air separates into two distinct airflows: one hot and one cold.
Step 2: Vortex creation
The airflow creates a rotational vortex that can exceed 1,000,000 RPM.
Step 3: Thermal separation
The compressed air separates into two distinct airflows: one hot and one cold.
Step 4: Cold air generation
The cold airflow exits at temperatures down to -45°C depending on the inlet pressure.

Best practices for optimizing a vortex tube
Compressed air quality
To ensure optimal performance, the vortex tube must be supplied with dry, clean compressed air filtered to 5 μm. The tube and air supply connection must not have any flow restrictions with a diameter smaller than 8 mm.
Cooling adjustment
The restriction valve located on the hot air outlet allows adjustment of both the airflow rate and the cooling level achieved at the cold outlet.
Airflow vs temperature
A high cold airflow produces greater cooling capacity, but with a smaller temperature drop. Conversely, a lower cold airflow achieves lower temperatures with reduced cooling capacity.
Pressure influence
Higher compressed air pressure increases the temperature drop achieved at the cold outlet. Lower pressure reduces cooling performance.
