he foolproof operation of our DFRA series dehumidifiers is based on the principle of two continuous and simultaneous airflows running in opposite directions through the desiccant rotor: the process airflow (airflow requiring dehumidification) and the reactivation airflow for the desiccant rotor (wet air).After filtration, the process airflow passes through the desiccant rotor, which adsorbs most of the water vapour contained in the air stream. This is then expelled from the dehumidifier via a fan, in the form of dry air for supply to the process ventilation system or direct to the space in question. The reactivation airflow for the desiccant rotor is drawn from outside, filtered and heated by electricity/steam/thermal oil, or via a direct combustion natural gas burner. When it has reached the temperature required to carry over the molecules of water vapour retained in the rotor, this wet air is extracted from the dehumidifier by a fan and expelled to the outside. Our dehumidifiers are specially designed for easy installation, stable and continuous operation with minimum maintenance.
Using the latest technology, the operating principle of FISAIR desiccant air dehumidifiers is based on the use of an exclusive, high performance, desiccant silica gel rotor to retain the water vapour.
The effective dehumidification of the process airflow is achieved by the high efficiency of the desiccant silica gel rotor which adsorbs molecules of water vapour, maintaining its performance even at low levels of ambient humidity. The synthesized silica gel is a chemically and thermally stable material, which is not subject to deliquescence like other desiccant materials and therefore provides continuous and stable performance. This silica gel is the foundation for the long service life provided by FISAIR dehumidifiers, as its chemical resistance plus its ability to be washed with water, ensures its longevity. Process air humidity values down to -20ºC Dew Point can be readily achieved, and even more demanding level are available on request.
