FX refrigerant dryers Industrial performance – simple reliability


Refrigerant circuit


1 Refrigerant separator

ensures that only refrigerant gas can enter the compressor, as liquid would cause damage.


2 Refrigerant compressor

brings the gaseous refrigerant to a high pressure and a high temperature.


3 Max. pressure switch

(only FX 13-21)


4 Fan control pressure switch

(only FX 13-21)


5 Condenser fan


6 Condenser

cools the refrigerant slightly so that it changes from gas to liquid; refrigerant is more effective in the liquid state.


7 Capillary filter

protects the expansion device from harmful particles.


8 Capillary tube

reduces the refrigerant’s pressure, thereby lowering its temperature and increasing its cooling capacity; the refrigerant is now almost all liquid, with some residual gas.


9 Hot gass bypass

regulates the amount of refrigerant passing through the air-to-refrigerant heat exchanger, ensuring a stable pressure dewpoint, and eliminating the chance of the condensate freezing.



Air circuit


10 Air inlet

hot saturated air enters the dryer and is cooled by the outgoing air via the air-to-air heat exchanger. Reducing the temperature of the inlet air reduces the load on the refrigerant circuit.


11 Air-to-refrigerant heat exchanger

transfers heat from the compressed air to the cold refrigerant, forcing water vapour in the compressed air to condense. The more effective the heat transfer, the cooler the air becomes and the more water vapour condenses.


12 Air/ air heat exchanger


13 Water separator

collects and drains off condensate from the cooled air flow. The more efficient the separation, the better the pressure dewpoint, as droplets which are not collected revapourise and degrade the pressure dewpoint. The collected droplets are reliably evacuated from the separator through an electronic drain.


14 Automatic drain


15 Air outlet

re-heats the outgoing air to prevent condensation on the factory’s pipework.


No installation is complete without filtration

Adding filtration to the installation will further increase the quality of the air, resulting in even less chance that tools and machines will be damaged and final product quality compromised.


1 The prefilter will protect the dryer, and also remove free water, particles to 1 micron and oil to 0.1 mg/m3.


2 The final filter removes particles to 0.01 micron and oil to 0.01mg/m3.


3 The final result is dry clean air, which allows you to concentrate on your business, without problems.
