Vortex Tubes Sub-Zero Spot Cooling using Compressed Air Vortex tubes...our founding technology. More than 40 years ago, we pioneered the application of the vortex tube principle to solve industrial cooling problems. Maintenance free, no moving parts Cycle repeatability within – 1° Drops inlet temperature by up to 38°C Cools without electricity or refrigerants Exceptionally reliable, compact and lightweight Over the years, thousands of companies of all sizes have used ITW Vortec vortex tubes on their equipment to spot cool a part or process, thermal test components, speed set solders or hot melt...

Vortex Tubes The table below shows approximate temperature drop and rise achieved by vortex tubes when adjusted to various Cold Fractions. A Cold Fraction is the percentage of cold air produced versus total filtered compressed air consumed by any Vortex Tube. COLD FRACTION PSIG/BAR Table Baseline: Compressed air temperature: 70˚F/ 21˚C Pressure Dew Point: -69˚F/-56˚C (dry air) Backpressure: not to exceed 5 PSIG/0.4 Bar Numbers on the Blue Bar: Temperature Drop Numbers on the White Bar: Temperature Rise All Vortex Tubes are Easily Adjusted to Regulate Airflow Volume and Temperature Vortex Tube...

Vortex Tubes With our models ranging from approximately 6” to 13” long, Vortex Tubes are a very compact source of refrigeration and spot cooling capability. They are designed to utilize a filtered compressed air supply of 80 - 110 PSIG. Pressures lower than 80 PSIG will still provide some cooling, but temperature drops and flows are reduced due to the lower inlet pressures. To prepare the air source, an appropriate filter/separator must be used, placed as near to the Vortex Tube as possible. ITW Vortec’s Auto-Drain filters-separators incorporate a 5 micron filter that effectively removes dirt,...

Cold Air Guns Versatile Spot Cooling for Machining and More If you want to substantially improve your dry machining operations, kill the heat buildup with a steady stream of sub-zero air from a Cold Air Gun. Cold air machining on almost any material results in improved production rates and quality, as well as prolonged tool life. And, with the ever-increasing need to protect worker breathing areas, you can eliminate the mess, expense and safety concerns associated with using mist coolants. Cold Air Guns use filtered compressed air and vortex tube technology to produce sub-zero air for numerous...

Cold Air Guns Model 610 Adjustable Cold Air Gun System Our most popular and versatile model is ideal for a wide range of machining operations and other spot cooling needs. The Cold Air Gun’s easily adjustable temperature and airflow settings and instant on/off capability makes it simple to adapt its cold air output to the application. x Eliminates the mess, expense and safety concerns of using mist coolants x Avoid secondary parts cleaning after machining x Cools parts to reduce normalization time and hold tight part tolerance x Single turn adjustable temperature for your specific application...

Model 608 Mini Cold Air Gun Model 424 Thread Guard Needle Cooler Model 610 Adjustable Cold Air Gun 80-100 PSIG recommended for optimum performance. System models 610, 608, 609 and 424 include a 5 micron Auto-Drain filter. Increase dry machining speeds up to 36% and extend tool life up to 50% Control Valve Optional flex nozzles are available to improve the cold air delivery in certain applications. A Dual-Point Nozzle (for the #608 or #610 models) is effective for cooling a larger surface area or two sides of a machined part or area,...

Enclosure Coolers Keep Electrical Enclosures Cool, Clean and Protected Have your production lines or equipment ever shutdown from overheated electrical enclosures? It’s a common problem, and one that can have serious consequences. Research by control manufacturers has shown that for each 18°F (10°C) increase in temperature, online production shutdowns will occur twice as often. Vortex Coolers offer a simple, reliable and affordable solution to keeping control panels cool, clean and protected. Thermostaticallycontrolled to save energy Continuous cooling models are available Powered by compressed...

Enclosure Coolers With no moving parts to wear out or maintain, Vortex Coolers use only compressed air and vortex tube technology to produce quiet, efficient and reliable cabinet cooling. As an added benefit, these coolers create a slight positive pressure inside the enclosure to prevent dirt or dust from entering even in the most challenging environments. From small computer cabinets and touch-screen control panels to large electrical enclosures, a Vortex Cooler can protect sensitive controls from overheating to eliminate heat and dirt related shutdowns. Models are available to provide cooling...

Enclosure Coolers All Vortex Cooler systems include a 5-micron Auto-Drain filter and a ducting kit to distribute cold air throughout the enclosure. Thermostatically controlled models also contain a solenoid valve and thermostat, limiting compressed air usage to those times when cooling is required. All Vortex Coolers are UL-listed and maintain NEMA 4, 4x and 12 ratings based on selected model. Coolers are designed to use a filtered factory compressed air supply of 80 -100 PSIG.
