The quality and efficiency requirements demanded by today’s society in terms of human comfort, and the control and stability of production processes, have made humidity control increasingly necessary or even essential.

The fact that the water vapour content of air varies greatly, and relative humidity depends on this, means it is vital to employ a dehumidification system for the reduction and control of this value whenever the water vapour content exceeds the humidity content permitted by the process.

That is why Fisair, which has been manufacturing since 1995, designs air dehumidifiers that enable the constant attainment of required humidity levels in a simple and precise manner, for minimal investment and operating costs.

Operating principles of desiccant rotors

DFRA series Fisair air dehumidifiers work using a high performance silica gel desiccant rotor, which is chemically and thermally stable, to prevent the deliquescence of the material it is made of, as occurs with other desiccant materials. Its cylindrical shape with a large number of small channels provides a large surface area for contact between the air and the desiccant material, which enables high levels of dehumidification, with a minimal volume of material.

Its simple method involves two air flows moving continuously and simultaneously as counter-currents across the desiccant rotor. The desiccant rotor is equipped with a rotation device and a series of perimeter seals to make the drying process continuous and uniform, and to optimize performance.

The flow of air for drying (process air), is filtered and passes through the desiccant rotor material (270º), and a proportion the water vapour molecules in the air are adsorbed. This air (dry air) is supplied to the controlled humidity zone by means of a fan.

The regeneration air flow from the desiccant rotor (reactivation air), is filtered and heated using an electric heater coil. It then passes through the desiccant rotor material (90º), and the water vapour molecules retained in the desiccant rotor are adsorbed, which regenerates the rotor for a new drying cycle. This air (wet air) is expelled outside of the controlled humidity zone, by means of a fan.

Fisair dehumidifiers have a long operating life because of the chemical resistance of the rotor and the possibility of washing it in water.

Standard dehumidifiers can ensure dry air humidity reaches dew point temperatures of up to -20ºC, or even lower on demand.

Practical example: Starting with a DFRA-0300-E with 14.3 kg/h (at 20ºC and 60% R.H.), we want to know the capacity if the air being handled is at 30ºC and 70% R.H. The table shows us that a Correction Coefficient of 135% must be applied,

which gives a new capacity of 14.3-1.35= 19.31 kg/h (at 30ºC and 70% R.H.).
