Third filtration tower
14 July 2016
The Atacama range of modular air dryers manufactured by Hi-line Industries has been extended to incorporate a third filtration tower, ensuring full compliance with BS EN 12021 standard ‘Respiratory equipment – Compressed gasses for breathing apparatus’. This is currently the only standard to indicate contaminant levels for breathing air both in the UK and EU.
This development means appropriate models in the Atacama range can now be safely utilised in the most demanding environments. Bulk water, in liquid and gaseous form needs to be eliminated from the breathing air. BS EN 12021 states that this should be at a pressure dewpoint not exceeding -11°C.
The ‘Atacama – CT’ breathing air dryer is controlled by the proven Hi-line HDC 1 controller. This solid state digital controller not only has an LED digital dewpoint display, but has dewpoint control built-in as standard. This is pre-set on the breathing air application to change over to stand-by once a dewpoint of -15°C PDP is achieved. This ensures security for air quality, whilst also maintaining energy efficiency.
