In industrial environments, spot cooling, panel cooling, tool cooling, and thermal conditioning are often required in areas where conventional cooling systems may be difficult to install or maintain. Applications involving dust, vibration, limited space, high temperatures, or hazardous conditions require compact, reliable, and maintenance-friendly solutions.
The Envortex Vortex Tube is designed for these demanding industrial needs. It uses only clean and dry compressed air or gas to generate two separate air streams at the same time: one cold and one hot. With no moving parts, no electrical power requirement, and no chemical refrigerants, Envortex provides a practical and environmentally friendly solution for industrial cooling and heating applications.
What Is Envortex?
Envortex is a Ranque-Hilsch Vortex Tube. It is a thermodynamic device that separates compressed air into hot and cold air streams without using any moving mechanical components.
Compressed air enters the tube and is converted into a high-speed vortex. Through this process, the air separates into two different temperature zones. Cold air exits from one side of the tube, while hot air exits from the other side.
Because the system does not require electricity or refrigerant gas, it is especially suitable for difficult-to-maintain areas and industrial environments where simple, compact, and durable cooling is required.
Operating Principle
The working principle of Envortex is based on the Ranque-Hilsch effect. Compressed air is injected tangentially into the tube through nozzles. This creates a very high-speed rotating airflow along the inner wall of the tube.
The outer vortex moves toward the hot end of the tube, where part of the air is discharged through an adjustable control valve as hot air. The remaining air moves back through the low-pressure central region of the tube, forming an inner vortex that flows in the opposite direction toward the cold end.
During this process, the inner airflow transfers kinetic energy to the outer airflow and undergoes rapid adiabatic expansion. As a result, the central air stream cools significantly and exits through the cold air outlet.
No Moving Parts, Low Maintenance
One of the most important advantages of Envortex is its simple and robust structure. Since there are no moving parts inside the tube, there is no mechanical wear under normal operating conditions.
This makes Envortex suitable for continuous industrial use, especially in environments where maintenance access is limited. As long as the device is supplied with clean and dry compressed air and is protected from mechanical damage, it can operate reliably for many years.
Environmentally Friendly Cooling
Envortex does not use chemical refrigerants and does not require electrical energy for operation. It works only with compressed air or gas.
This makes it an environmentally friendly alternative for localized cooling applications. It can be used in production areas, control panels, machining processes, electronic systems, and other industrial applications where compact cooling is needed without conventional refrigeration equipment.
Technical Features
Envortex is available in two main model options: Envortex 01, the standard model, and Envortex 02, the high-capacity model.
The body material is 304 stainless steel as standard, with 316 stainless steel available as an option. The maximum operating pressure is 7 bar / 100 PSIG. Air consumption is approximately 6 m³/hour, depending on the model.
The O-ring material is NBR as standard, with Viton available as an option. The cooling capacity is up to 1300 BTU/hour for Envortex 01 and up to 3300 BTU/hour for Envortex 02. Connection options include R 1/4" with 8 mm hose inlet and R 1/2" with 12 mm hose inlet. The sound level is approximately 70 dB at 7 bar, and the product weight ranges from 450 g to 1350 g, depending on the model.
Recommended Cooling Ratio
The catalog recommends a cooling ratio of approximately 70–80%, within the limit where condensation does not occur. If condensation occurs, the vortex tube may not operate properly.
The cooling effect depends on the balance between the cold-side air temperature and the amount of air discharged from the cold outlet. For this reason, correct adjustment of the hot-end control valve is important for achieving stable cooling performance.
Application Areas
Envortex can be used in a wide range of industrial sectors. In metalworking and manufacturing, it is suitable for cooling CNC tools, turning tools, milling cutters, taps, saws, drills, and other cutting tools. This helps control heat generated by friction, extend tool life, and improve machining accuracy.
In welding processes, it can be used to cool welded parts and welding machines. In laser cutting and optical systems, Envortex can help prevent overheating and protect sensitive optical components.
For electrical and electronic applications, Envortex is suitable for cooling electrical panels, server cabinets, PLC systems, variable speed drives, servo motors, sensors, and industrial cameras. When used for panel cooling, it can also create a slight positive pressure inside the cabinet, helping to prevent dust, moisture, and dirt from entering.
In energy, gas, and petrochemical applications, vortex tubes can support temperature management in pressure reduction stations, fuel conditioning, LNG and CNG applications, and specialized gas processing systems.
Envortex can also be used in food, pharmaceutical, and chemical industries for rapid cooling, drying, temperature conditioning, and laboratory testing applications.
Optional Accessories
Envortex can be supplied with optional accessories for different installation requirements. For panel cooling applications, regulator, filter, solenoid valve, and thermostat-sensor components can be used.
A wall mounting apparatus is available for fixed installation. A cooling-fluid apparatus can also be connected after the cold outlet for special machining applications. According to the catalog, this accessory is customer-designed and does not affect the cooling performance of the vortex tube itself.
Why Choose Envortex?
Envortex is a strong choice for applications requiring compact, fast, and reliable spot cooling or heating. It provides immediate response, requires no electricity, contains no moving parts, and uses no chemical refrigerant.
Its stainless steel body, lightweight design, and simple installation make it suitable for harsh industrial environments. It is especially advantageous in areas where conventional cooling systems are too complex, too large, or too maintenance-intensive.
Conclusion
The Envortex Vortex Tube is an efficient and durable compressed-air cooling and heating solution for industrial applications. By using the Ranque-Hilsch principle, it separates compressed air into hot and cold streams without electricity, refrigerants, or moving parts.
With two model options, stainless steel construction, cooling capacities up to 3300 BTU/hour, and a wide range of accessories, Envortex offers a flexible solution for machining, panel cooling, electronics, energy systems, food processing, chemical applications, and many other industrial processes.
For companies looking for compact, maintenance-friendly, and environmentally responsible cooling technology, Envortex provides a practical and reliable alternative.
