REFRIGERATED DRYER

Refrigerated dryers are used almost everywhere in compressed air networks and are ubiquitous. They are by far the most economical way to obtain dry compressed air: by lowering the temperature of the compressed air, the water vapour present condenses into liquid water. For all applications where stable conditions are essential, Javac’s KM series offers the most efficient solution.

Water is not welcome for compressed air users, but where does it come from? Water is part of air, and it is the enemy of any compressed air system. The compressor not only compresses the air, but also the moisture in it, and this moisture accumulates in the compressor receiver, the tools and the air lines. The consequences are easy to predict: rust, parts seize up, lubricating oil in your pneumatic tools is washed away, etc. This quickly becomes very costly: production losses, process disruptions and interruptions to your productivity. This water originates from the air entering the compressor as harmless vapour.

During compression and aftercooling, however, water droplets form and are responsible for the problems. Installing a compressed air dryer will prevent these costly “ailments”, because it removes virtually all harmful moisture; only dry air is fed into the piping network, ensuring efficient operation of the installation at minimal cost. The Javac KM refrigerated compressed air dryers are suitable for drying compressed air for industrial use. These are machines with direct expansion and dry evaporation. The air is directed over the heat exchanger, where the moisture in the compressed air condenses at a 3°C dew point; the condensate collects in the separator and is discharged via a solenoid valve to the automatic drain point.
