The Fiac EDRY 12 cycling refrigeration dryer allows filtering and dry the compressed air produced by the compressor, this process will produce better quality compressed air without any kind of residue, but above all it will avoid the formation of condensation inside the tank and the occurrence of any damage due to steam.
The atmospheric air sucked in by a compressor is a mixture of gas, water vapour and solid contaminants, and without the use of a treatment system these pollutants could reach the machines and create damage. The air also contains a certain amount of humidity, in greater amounts at higher temperatures. This accumulation can create problems and disturbances to the compressor, and as mentioned above, also to the connected equipment.
For example: a compressor with an operating pressure of 7 bar and a capacity of 200 L/s that compresses air at 20°C with a 80% relative humidity, injects 10 litres of water per hour into the compressed air line.
To avoid this, it is necessary to dry and filter the compressed air, especially in machines that produce air for long periods of time. The cycling refrigeration dryer allows filtering and dry the compressed air produced by the compressor, this process will produce better quality compressed air without any kind of residue, but above all it will avoid the formation of condensation inside the tank and the occurrence of any damage due to steam.
The drying process, or cooling, of compressed air allows it to condense, and subsequently separate large amounts of water. The air is re-heated after this process, thus avoiding the formation of condensation inside the tank. In addition, this heat exchange between the incoming and outgoing air also reduces the cooling capacity required by the circuit.
Using a compressor without a dryer can cause various problems to the system or the connected equipment, such as:
Corrosion of the equipment and piping system;
Damage to the pneumatic controls, with the possibility of safety shutdowns;
Need for continuous and excessive maintenance;
Possibility of icing when working at low temperatures;
Quality problems due to discolouration regarding paint adhesion;
