ARIANA b.ca.-30°C Cold Air Nozzle – adjustable cold output, 3/8" thread

The ARIANA b.ca.-30°C Cold Air Nozzle provides targeted cooling for metal and plastic components on machine tools where liquid coolants are undesirable.

• Targeted cooling down to −30°C
• Operates on compressed air, 3–8 bar
• Adjustable volume flow and cold-air ratio

Precision cooling where liquids are not an option

The nozzle delivers focused point cooling for machining and finishing operations, enabling rapid temperature reduction without introducing fluids. Driven by compressed air at 3–8 bar, the device produces a cold stream reaching approximately −30°C, making it suitable for temperature-sensitive tasks on both metal and plastic components. The absence of mist or coolant prevents contamination of parts and fixtures, supporting quality-critical production and cleaner downstream processes.

Reliable temperature separation through the vortex tube principle

Using the vortex tube principle, the unit separates compressed air into two counter-rotating streams that exit as distinct hot and cold flows. The cold-air outlet appears on the blue side, while the red side emits the warm exhaust; the hot stream may reach up to 60°C. A simple set screw controls both the volume flow and the cold-air proportion, allowing precise adaptation of cooling intensity for repeatable results and reduced cycle variation.

Flexible mounting and practical accessories for quick deployment

Connection is provided via a 3/8" thread, and the nozzle is supplied with practical accessories for rapid integration: the ARIANA Cool-Line system (½"), a magnetic plate, a ball valve, a threaded nipple for quick coupling, and a silencer. These components enable easy repositioning and vibration-resistant mounting, while the silencer reduces acoustic impact during continuous operation, improving the working environment on the shop floor.

Operational advantages that support productivity and process integrity

The equipment minimises the need for cleaning and rework by avoiding liquid contamination and offers localised thermal control to limit thermal distortion and maintain tight tolerances. With both cold and hot streams available, the nozzle can assist in temperature equalisation as well as rapid cooling, supporting versatile workflows in workshops and toolrooms. The combination of adjustable output and robust accessory options supports efficient integration into existing pneumatic systems and helps maintain consistent part quality.

FAQ

What pressure is required for correct operation?
Operation requires compressed air at 3–8 bar; the ARIANA cold air nozzle performs reliably within this pressure range.

Which materials can be cooled with this nozzle?
The nozzle is designed for point cooling of metal and plastic parts on machine tools where liquid coolants are unsuitable.

How is the cold output adjusted?
Adjustment is via a set screw that controls volume flow and the cold-air ratio to fine-tune cooling intensity for the task.

Does the nozzle produce both cold and hot air?
Yes — the device separates air into cold and hot streams; the cold exits at the blue outlet and the hot at the red outlet, with the hot stream reaching up to 60°C.

What accessories are included for installation?
Included are the ARIANA Cool-Line system (½"), a magnetic plate, ball valve, threaded nipple for quick coupling, and a silencer; SKU 4522222000NW identifies this configuration.
