Atmospheric air which is drawn into the compressor always contains humidity. The amount of humidity depends on the temperature. Humidity is the biggest factor in the compressed air system, when the humidity is cooled it turns to condensate and may cause serious damage to your air distribution system and your equipment, the condensate must be separated in order to archive perfect dry air. The MDX range 400 – 84000 refrigerant dryer removes the condensate discharge dew to their intelligent discharger. The MDX design is very compact and simple to install.
