• Cold Air Guns
• Vortex Tubes

ITW Vortec's vortex tube products have been solving industrial cooling problems for years. Using only filtered, factory compressed air as a power source, they convert ordinary compressed air into two air streams -- one hot and one cold. At 100 PSIG (6.9 Bar) and 70ºF (21ºC) inlet temperature, a vortex tube can produce refrigeration up to 6000 BTUH (1512 kcal/H) or temperatures to -40ºF (-40ºC).

Choose one of our Cold Air Guns for quick, easy installation or the model from our complete vortex tube line that best fits the specific needs of your application.

Cold Air Guns Cold Air Guns incorporate a vortex tube in a system designed to fit the needs of many common vortex tube applications.	Use the Model 610 Adjustable Cold Air Gun to increase feed rates and tool life, or cool parts and industrial processes.
Features: Cool without refrigerants (CFCs/HCFCs) or moving parts for reliable, trouble-free operation. Use no electricity -- intrinsically safe, no RF interference. Include an integral muffler for quiet operation -- within OSHA noise specifications. Are powered by filtered compressed air.

Model 610 Adjustable Cold Air Gun
The Model 610 Adjustable Cold Air Gun is ideal for use in machining applications and for cooling parts and industrial processes. Model 610's adjustable feature allows you to set the cold airflow rate (BTUH) at optimum levels for your application. The Adjustable Cold Air Gun's maximum temperature drop is 100Fº (55.6Cº) below inlet air temperature and the maximum cooling capacity is 1500 BTUH (378 kcal/H). Model 610's compressed air supply requirement is 15 SCFM (425 SLPM) at 100 PSIG (6.9 Bar).

Model 610 comes complete with a flexible nozzle for directing cold air and a magnetic base for quick, easy installation and use.

Model 608 Mini Cold Air Gun ITW Vortec's Mini Cold Air Gun is designed to shave hours off your dry surface grinding operations. By providing a contamination-free source of cooling, it effectively cools parts to reduce normalization time, hold tighter tolerances, reduce wheel loading and improve surface finish quality. Its adjustable magnetic base allows instant installation and positioning near the wheel for maximum cooling performance. Its compact size won't interfere with grinding operations. Model 608's compressed air supply requirement is 8 SCFM (227 SLPM) at 100 PSIG (6.9 Bar).

Model 424 Thread Guard® Needle Cooler
Watch your piece rate jump with ITW Vortec's Model 424 Thread Guard®. Thread Guard delivers a continuous stream of cold air onto the sewing machine needle to virtually eliminate downtime caused by needle breakage and thread burning caused by overheating. It's effective even in the most challenging sewing operations including belt loops and tough materials. Cooling also prevents holes caused by hot needles burning synthetic fabrics. Model 424's compressed air supply requirement is 4 SCFM (113 SLPM) at 100 PSIG (6.9 Bar).

Vortex Tubes are available in many sizes offering a range of cooling capacities. Vortex Tubes Vortex Tubes are available in a wide range of sizes to meet the needs of many process and spot cooling applications. Vortex Tubes offer cooling capacities beyond those available from our Cold Air Guns. Features: Cool without refrigerants (CFCs/HCFCs) or moving parts for reliable, trouble- free operation. Use no electricity -- intrinsically safe, no RF interference. Compact and lightweight for easy installation -- even in tight areas.

Vortex Tube Phenomenon The vortex tube was discovered in 1930 by French physicist Georges Ranque. Vortec was the first company to develop this phenomenon into practical, effective cooling solutions for industrial applications. Here's how it works. Fluid that rotates about an axis -- like a tornado -- is called a vortex. A vortex tube creates a vortex from compressed air and separates it into two air streams -- one hot and one cold. Compressed air enters a cylindrical generator which is proportionately larger than the hot (long) tube where it causes the air to rotate. Then, the rotating air is forced down the inner walls of the hot tube at speeds reaching 1,000,000 rpm. At the end of the hot tube, a small portion of this air exits through a needle valve as hot air exhaust. The remaining air is forced back through the center of the incoming air stream at a slower speed. The heat in the slower moving air is transferred to the faster moving incoming air. This super-cooled air flows through the center of the generator and exits through the cold air exhaust port.

BTUH (kcal/H) capacity based upon 70ºF (21ºC) compressed air dried to a dewpoint of -40ºF (-40ºC).

* Airflow temperature can be dropped up to an additional 20ºF (11ºC). Colder airflow temperatures are produced by adjusting the needle valve to increase the hot airflow. The needle valve is located in the hot exhaust. Vortex Tubes produce less airflow at colder temperatures and have less BTUH (kcal/H) capacity.
