In industrial facilities, electrical cabinets, PLC systems, variable speed drives, servo control units, relay groups and sensitive electronic equipment can be exposed to high temperature, dust, humidity and dirt. When the internal cabinet temperature rises, electronic components may lose service life, failure risk may increase and production continuity may be affected.
Envortex cooling panels are compressed-air-based cooling systems developed for this requirement. The system consists of an Envortex cooling tube, regulator, water separator, solenoid valve and thermostat. With this structure, cabinet temperature can be kept under control while a slight positive pressure inside the cabinet helps reduce the ingress of dust, moisture and dirt from the outside environment.
What Is an Envortex Cooling Panel?
An Envortex cooling panel is a practical cooling solution used to reduce the internal temperature of electrical and automation cabinets. The main cooling element of the system is the Envortex vortex tube.
The Envortex vortex tube is a thermodynamic device that produces two different air streams, hot and cold, at the same time by using only clean and dry compressed air or gas, without any moving parts. In cabinet cooling applications, the cold air is directed into the cabinet, while the hot air is discharged outside the system.
Unlike conventional fan-based cooling systems, Envortex does not draw ambient air directly into the cabinet. This makes it especially advantageous in dusty, humid, dirty or maintenance-challenging industrial environments.
Main Components of the System
Envortex Cooling Tube
The Envortex cooling tube is the core component of the system. It separates compressed air into hot and cold air streams. The cold air is directed into the electrical cabinet, while the hot air is exhausted outside.
According to the catalog, Envortex 01 is the standard model and Envortex 02 is the high-capacity model. The maximum cooling capacity is 1300 BTU/hour for Envortex 01 and 3300 BTU/hour for Envortex 02.
Regulator
The regulator is used to adjust the compressed air pressure entering the system. For efficient operation, the air pressure must be kept at the correct level.
The catalog specifies a maximum working pressure of 7 bar / 100 PSIG. Therefore, the regulator helps stabilize the air supply and supports consistent cooling performance.
Water Separator / Filter
The Envortex system requires clean and dry compressed air. Moisture, water droplets, oil or particles in the air line may reduce cooling performance and affect reliable operation.
The water separator and filter condition the compressed air before it reaches the vortex tube. This component is especially important in electrical cabinet cooling applications, where stable and dry air supply is critical.
Solenoid Valve
The solenoid valve automatically opens and closes the compressed air supply. The thermostat monitors the internal cabinet temperature and activates the solenoid valve when the temperature reaches the set value.
This allows the system to operate only when cooling is needed. As a result, compressed air consumption can be reduced and the system can operate more economically.
Thermostat
The thermostat monitors the cabinet temperature. When the temperature rises above the set point, it sends a signal to open the solenoid valve and start cooling. When the temperature returns to the desired range, the solenoid valve closes and air consumption stops.
This automatic control structure helps keep electronic components operating under more stable temperature conditions.
Working Principle
The Envortex cooling panel operates by sending clean and dry compressed air into the vortex tube. The air enters the tube tangentially and rotates at very high speed. This process separates the compressed air into two different streams.
The outer air stream becomes hot and is discharged from the hot air outlet. The inner air stream cools down and exits from the cold air outlet. This cold air is directed into the electrical cabinet.
In cabinet cooling applications, the thermostat continuously monitors the cabinet temperature. When the temperature exceeds the set point, the solenoid valve opens and compressed air flows into the Envortex tube. Cooling begins immediately. When the cabinet temperature decreases to the required level, the solenoid valve closes and compressed air consumption stops.
Why Use Envortex for Cabinet Cooling?
Electrical cabinets often operate in hot, dusty and humid industrial environments. Fan-based systems may carry dirty ambient air into the cabinet, increasing contamination risk. Air conditioner units can be more complex, more expensive and more maintenance-intensive.
Envortex cooling panels offer a compact and practical alternative. Since the system has no moving parts in the cooling tube, maintenance requirements are reduced. It does not require a cooling compressor or chemical refrigerant; it operates only with compressed air.
The cold air supplied into the cabinet can also create a slight positive pressure. This helps reduce the entry of dust, moisture and dirt from the external environment.
Technical Advantages
One of the most important advantages of the Envortex vortex tube is that it has no moving parts. This minimizes mechanical wear and supports long service life.
The system does not require an electrical cooling compressor or chemical refrigerant. It operates with clean and dry compressed air, making it practical for dirty or maintenance-sensitive industrial environments.
According to the catalog, the standard body material is 304 stainless steel, with 316 stainless steel available as an option. The standard O-ring material is NBR, with Viton available as an option. The sound level is approximately 70 dB at 7 bar.
Envortex 01 and Envortex 02 Model Selection
The Envortex series includes two main models. Envortex 01 is the standard model and is suitable for lower cooling demand. Envortex 02 is the high-capacity model and is preferred for larger cabinets or applications with higher heat load.
The catalog shows Envortex 01 with 8 mm hose inlet and R 1/4" connection, while Envortex 02 is shown with 12 mm hose inlet and R 1/2" connection. Model selection should consider cabinet volume, internal heat load, ambient temperature, compressed air capacity and the required temperature reduction.
Importance of Air Quality
Air quality has a direct effect on Envortex performance. The compressed air must be clean and dry. If condensation or water is present in the air line, the vortex tube may not operate properly.
The catalog recommends a cooling ratio of 70–80%, within the limit where condensation does not occur. It also states that if condensation occurs, the vortex tube cannot operate properly.
For this reason, the water separator and filter are not just auxiliary components; they are essential for reliable cabinet cooling operation.
Application Areas
Envortex cooling panels are mainly used in electrical and electronic applications. Typical applications include electrical cabinets, server cabinets, PLC systems, variable speed drives, servo motor control panels, automation cabinets and sensitive electronic systems.
They can also be used for sensors and industrial camera systems operating under high temperature conditions. In dusty and dirty production areas, Envortex cooling panels help protect internal cabinet equipment from overheating and contamination.
Benefits for Industrial Users
Envortex cooling panels help reduce the internal temperature of electrical cabinets and support safer operation of electronic components. Lower cabinet temperature can reduce temperature-related failures, decrease maintenance costs and improve production continuity.
The automatic structure with solenoid valve and thermostat prevents continuous air consumption. The system operates only when cooling is required, making compressed air usage more controlled.
Its compact design makes it suitable for integration into existing cabinets. Since the cooling tube has no moving parts, maintenance requirements are low.
Why Choose an Envortex Cooling Panel?
Envortex cooling panels provide a simple, durable and effective cooling solution for electrical cabinets. They are especially useful where fan cooling is insufficient, air conditioners are too costly or ambient air should not be drawn into the cabinet.
With stainless steel construction, compact design, instant response, environmentally friendly operation and automatic temperature control, Envortex cabinet cooling systems provide reliable performance in demanding industrial environments.
