Elen Enclosures has a simple and economic system to cool sensitive instrumentation, electronics and communications equipment or components in enclosures and cabinets located in harsh, dirty and hot industrial or hazardous (Ex) locations. Powered by compressed air, the stainless steel coolers are easy and quick to install.
The system protects the components by cooling the internal air in the enclosure below the ambient temperature, removing humidity, inhibiting corrosion and maintaining positive air pressure to prevent the ingress of water, dust, oil mist and hot ambient air.
The Vortex Tube cooler generates cold air without moving parts and refrigerants. This results in exceptional reliability. Maintenance is minimal - if any. Air consumption can be minimised using a thermostat combined with solenoid valve.
Model 20025 delivers approx. 800 W (2500 BTU/h) of cooling power. The cooling capacity is continuously adjustable at the 'hot end' valve. In applications requiring cooling power higher than 800 W the coolers can be installed in a 'battery' arrangement. Elen Enclosures will gladly help with the assessment of cooling requirements. Apart from Vortex coolers, the company is offering a full range of other cooling options such as filter fans, heat exchangers and maintenance-free filterless Nano-coated airconditioners.
How a vortex tube works
A vortex tube is a device with no moving parts that will separate a stream of compressed air into two streams - one hot and one cold. They can deliver air as cold as -35°C and hot air up to +127°C. Compressed air is injected tangentially into the tube's generator chamber at sonic speed, creating a cyclone (or vortex) spinning at about one million revolutions per minute. Following the curve of the inside of the tube, this spiralling column reaches the end of the vortex tube, where some of it is allowed to escape out the 'hot' valve. Air not leaving through the hot valve returns back down the centre of the tube, spinning inside the first vortex, leaving the tube at the opposite end as a cold stream. The inside column of air gives up its heat to the outside column. The temperature and airflow may be adjusted by means of the valve at the hot end of the tube.
