Industrial Spot Cooling & Process Cooling

Vortex tubes produce up to 6000 BTU/hr (1757 watts) of refrigeration and temperatures as low as -40 deg to solve a variety of industrial spot cooling and process cooling needs. With no moving parts, a vortex tube is highly reliable and inexpensive; and requires no electrical connection at the cooling site. Vortex tubes cool instantly, relying on compressed air spinning in the tube to separate the air into cold and hot air streams.

Vortex tubes are a compact source of refrigeration and cooling, with models ranging from 6 – 13 inches (150 – 330 mm) long and cooling capacities ranging from 100 – 6000 BTU/hour (29 – 1757 watts). Vortex tube performance is easily adjustable by changing the inlet air pressure, ratio of cool air to exhaust or by changing the generator in the tube itself. And while normally used for cooling, vortex tubes can also be used for heating applications, merely by channeling the exhaust hot air to the application..

Vortex tube technology was invented by French physicist Georges Ranque in 1930, and first developed for industrial use by Vortec in the 1960s. See how it works. Since then, vortex tubes have been applied for a wide range of cooling applications on machines, assembly lines, in processes and for testing and measurements.

Case Studies

Adjustable Vortex Tubes Set Manufacturer Up For Success
Company Overview Dyplast Products is a is a leading manufacturer of polyisocyanurate and expanded polystyrene products. This includes innovative and cost saving pipe, sheet and block rigid foam insulation for applications in temperatures up to 350°F (177°C). Their products are available in densities ranging from 2 to 6 lbs. per cubic foot and have thermal efficiencies that are greater than most of their competitor’s foam core products. These foam insulations are available in a variety of shapes and sizes and are used in a large range of industries around the globe.

The Problem The maintenance and safety manager at Dyplast Products contacted one of our Vortec applications engineers to explore cooling solutions available to chill sections of a steel conveyor on a process line. Each section of the conveyor is made of 12 gauge. steel plates. The plates are individually 64.5” long and 6” wide and weigh14lbs. Over a period of six hours, the temperature on the steel plates slowly rises from ambient temperature to 115-130°F (depending on the exothermic chemical process that occurs during transport on the conveyor). The internal temperature of the polyisocyanurate process called “bunstock” reaches 300°F. This heat was transferring into the steel conveyor surface. The maintenance manager needed to keep a 24” wide section in the center of the conveyor (where the bunstock is positioned) at 86°F or less for the process to remain viable, and to maintain the specifications and quality of the product. In the past this had not been an issue but changes in the ambient temperature and changes in the chemical process are causing new problems. Cadillac of South Charlotte is a stand-alone Cadillac dealer with a 9,300-square foot collision center. They have two paint booths, which keep Nutter and his two assistants plenty busy with prep, painting, and moving cars along to the curing oven. For the past four summers, Nutter has worn a 3M Versaflo face shield that supplies fresh air, keeping his face and head from overheating. Bruce Dunehew, the Collision Center Manager, was impressed by the effectiveness of the mask and wanted to expand protection to cool the whole body. “I was excited to see that Vortec offers a cooling vest!” -Dunehew

The Solution When other processes such as forced air ventilation, and heat extraction failed, Dyplast Products looked at vortex tubes. The company liked the idea of cooling steel plates using vortex tubes because it gave them the flexibility to easily move cooling from one section of the plant to another, based on the conveyors changing needs. The Vortec application engineers calculated that 8100 btuh of cooling would be needed to keep the 24” center sections of the plates at 86°F or lower. They suggested using a model 328-100-H and a 328-50-H vortex tube to produce 98 cfm of air at 0 to 10°F. The recommendation was to blow the cold air through an insulated manifold with 25 orifices to evenly distribute the air over the 24” wide section. The application engineer also created a sketch and a description to show how to construct the manifold and how to pipe and filter the compressed air supply to the two vortex tubes. The customer had concerns about the safety of the hot exhaust air from the vortex tubes, so the application engineer suggested a way to vent the hot air exhaust without affecting the performance. Another concern about over-cooling the steel plates arose which would potentially cause condensation. This problem was simple to solve, as the vortex tube’s cooling capacity can easily be controlled by regulating the inlet compressed air pressure to the vortex tube (with a pressure regulator).

The Result The maintenance manager purchased the 328-100-H and 328-50-H vortex tubes and a model 701S-40A150 scfm 5 micron compressed air filter and quickly installed them. The vortex tube solution worked so well that three months later the company ordered two more of each product for additional processing lines. Want to learn more about the Vortex Tube?

Protecting Robots In Extreme Environments
Company Overview In 1994, after a career of more than 20 years as an engineer designing products for major corporations in the field of robotics and automation, Charlie Tur identified a pressing yet unmet need among companies using robots. Tur decided to found a new company to fill that niche—creating suits to protect robots. More than a decade later, Tur’s company, Roboworld, has offices in both Ohio and Wisconsin and provides custom-built Robo suits to shield robotic equipment in extreme manufacturing environments. Roboworld’s worldwide manufacturing clients, such as Motoman, FANUC, and Lincoln Electric, benefit from well-designed robot “clothing” which protects their automation investments while increasing uptime.

The Challenge Roboworld Vice President for Design, Sales and Support Mike Tur explains “robots typically are placed in environments where you don’t want to put people—very hot or extremely cold environments, for example. The robots may also do highly repetitive tasks or handle work most human labor would find too unpleasant or unsafe to perform. This means these robots are subject to conditions which could potentially cause damage. Our suits protect them from such hazards...one of which is high temperature environments. However,in those high temperature environments, if you install a protective suit on an electrically-driven device (robot), the heat level can rise even higher than the ambient temperature. ” Thus the need for some method of cooling the robot suits is especially strong in these high heat environments.

The Solution Tur realized from the start that the company’s Robo suits required a cooling unit. Initially, the firm contracted with several air cooling equipment suppliers, including Vortec, for cooling tubes installed inside the suits. Over time, Tur notes, Vortec distinguished itself from the competition through “better pricing, prompt delivery of products as well as ease of operation —customers can quickly grasp the vortex tube concept and how it works.” He observes that “for years now, we’ve only used Vortec. There’s no reason to use another supplier.” Roboworld uses Vortec’s 308 and 328 series vortex tubes for their cooling applications. The Conclusion OVACO has been using Vortec products for four years. The company’s relationship with Vortec may expand in the future, Ireland says. “Given how successful our use of their products has been, I can see ordering more of what Vortec offers. I know they make several types of vests and we may order those at some point.” Ohio Valley Aluminum’s Corporate Safety Manager says that she has already informed other businesses of the excellence of Vortec’s products: “One of our contractors was visiting our site and I gave him one of the vests to wear and let him know who made it. I definitely recommend Vortec. They are excellent to work with.”

How Roboworld Benefits From Vortec Products Tur characterizes Vortec’s cooling tubes an affordable, effective solution while providing a high level of reliability. “We create a high quality product for our customers and we need cooling devices which stack up,” he states. He also notes that Roboworld has expanded its use of Vortec cooling products: “We now use them not just to cool the suits for robots themselves,but also to provide cooling in the covers we make for robot controllers.” The Conclusion Mike Tur observes that “We have a good relationship with Vortec because of the consistency and quality of their products and their service.” Thanks to his company’s positive experience with Vortec, Tur has referred clients seeking industrial cooling solutions to Vortec.
