Refrigerated Air Dryers


Nukor’s new NKD range of compressed air dryers offer unparalleled efficiency thanks to the use of a unique stainless steel, twin-pass heat exchanger and vortex water separator. The twin-pass heat exchanger pre-cools the incoming air with the exiting air resulting in energy savings of up to 30%.



The process of air compression concentrates atmospheric contaminants especially water vapor. This raises the dew point of the compressed air relative to free atmospheric air and leads to condensation within pipes as the compressed air cools downstream of the compressor. Excessive water in compressed air can cause a variety of operational problems such as corrosion in piping and equipment, malfunctioning of pneumatic process control instruments, fouling of processes and much more.


The main advantage of twin-pass dryers is that because the incoming air is cooled by the exiting air less energy is required to achieve the same level of cooling within the refrigerant circuit. This allows twin-pass coolers to operate more efficiently. The second advantage of the twin-pass process is that the outgoing compressed air stream is warmed by the incoming stream before being delivered thus eliminating the need for a dedicated heater stage within the dryer.
