Vortex Coolers

🔍 Vortex cooling principle

The principle of Vortex Coolers is based on the vortex tube effect, when the compressed air enters the vortex chamber, it will be separated into hot and cold air streams through high-speed rotation, and the temperature of the cold air flow can also be reduced to lower than the ambient temperature.

📏 How do you pick the right model?

1. Determine the Heat Load

• Measure the heat load inside the enclosure with BTU/hr or Watts.
• Consider heat generated by electrical components (e.g., transformers, PLCs, motor drives).
• Also consider for external heat, such as ambient temperature and solar radiation.

2. Identify the Required Cooling Capacity

• Use the formula:Cooling Required (BTU/hr) = Heat Load (Watts) × 3.41
• Compare this with the cooling capacity of vortex coolers available.

3. Consider the Enclosure Size and Material

• Larger enclosures require higher cooling capacity.
• Metal enclosures conduct heat differently than plastic ones.
• Ensure the vortex cooler fits within the available space.

4. Determine the Air Supply and Consumption

• Vortex coolers use compressed air (not electricity), so check:\✅ Available air pressure (typically 80-100 PSI required)\✅ Air consumption rate (measured in SCFM or L/min)

5. Consider Noise and Efficiency

• Vortex coolers can be noisy; so all the set will come with a muffler.
• For better solution, please also consider to purchase slenoid valve, air filter and thermostat.

6. Verify Installation Requirements

• Mounting options: Side, top, or door-mounted.
• Ensure proper airflow inside the enclosure for even cooling.
