The Vortex Tube Refrigerator PolarX - 508 is a fully instrumented benchtop vortex tube refrigeration module that operates on compressed air or another compatible gas source. It has no moving parts and generates cold air as low as -20°C with 75 watts of cooling capacity, while discharging hot air up to 70°C. The unit is rated at 300 liters free air per minute at 600 kNm-2 gauge and includes a concentric tube, counter flow heat exchanger. It is suited for specialized vortex tube refrigeration demonstrations and performance testing in laboratory and teaching environments.

Construction and Design
The Vortex Tube Refrigerator PolarX - 508 is built on a high-quality HDF panel. All components are mounted directly on this panel for a compact benchtop layout. The vortex tube refrigeration core is rated at 300 liters free air per minute at 600 kNm-2 gauge. A pressure regulator and filter supply clean, pressure-stable air to the system. The heat exchanger uses a concentric tube, counter flow design. Two valves control isolation and balance functions. Two variable area flowmeters, or optional orifices with digital output, measure airflow calibrated for air up to 4 gm s-1. Temperature is monitored using a digital temperature indicator with 0.1°C resolution, supported by thermocouple sensors.
