Features and benefits of the Vortex Coolers:
- Keep dust and moisture out of the control cabinet, prevent short circuits;
- Much shorter cooling response time than conventional systems (such as air conditioning / water cooling / Peltier cooling);
- Decrease the relative humidity to < 45% ! As a result, no condensation occurs and the control cabinet is dried;
- Cooling capacity 160 – 820 W, without the use of CFCs (Freon, etc.);
- IP 55 and IP 66 versions, Aluminum and stainless steel 316;
- Easy assembly, compact construction, no moving parts, maintenance-free;
- Noise level (<75 dB(A)), low purchase cost.
A vortex ‘cooling machine’ is a small T-tube into which the compressed air is introduced tangentially (e.g. at ambient temperature) and from which warm air (up to 120°C) is expelled at one end and cold air (up to 120°C) at the other end. colder than -50°C) leaves the tube. The incoming air (e.g. 7 bar(O)) expands in the Vortex chamber and cools down. A vortex (flow around an axis, as in a cyclone or tornado) is created in the direction of one end of the T-tube.
This airflow reaches a very high rotational speed (ie high speed), which gradually decreases towards the end of the tube, where the airflow heats up again. Part of the airflow is tapped at this warm air end. The remaining airflow is forced to move to the other end of the tube as a secondary internal vortex, dissipating heat to the warm airflow (primary vortex) that flows around it. The internal stream thus cools down. The desired cold air temperature can be set by responding to the warm air flow that is drawn off.
Vortex cooling can be used for local cooling of machines or for other specific applications where compressed air is available – cool with compressed air!
