High quality. Low dew points

    A large number of industrial materials and processes require dry air.

    • Of the numerous processes available for drying air, desiccant rotor technology has proven itself as providing the best combination of low installation costs, a greater range of applications, and the lowest operating costs.
    • FISAIR supplies a range of desiccant dehumidifier series adapted to specific applications.
    • Each series is equipped with the highest quality components and a design centred on simple maintenance and low energy consumption.

    Air dehumidifiers for the production of beer
    Water is used in beer making at every stage of the  production process.Changes in temperature are characteristic of beer production, the use of air dehumidifiers for beer production in transport, storage and production processes is vital, as well as improving quality in a clean, germ-free environment with humidity and temperature controlled.In mechanical transport, the installation of air dehumidifier for the production of beer:Prevents product from caking Improves the flow Prevents product from sticking in conduits, saving labor costs for cleaning Prevents production stoppages Ensures correct metering in automatic processesIn storage of intermediate product or finish, the absence of moisture results in less contamination and growth of bacteria, mold and fungi.Automatic dew point control by means of air dehumidifiers for the production of beer, in the tank, in the process areas, eliminates condensation and possible mold formation and quickly dries the periodic washing spaces.Most production operations are carried out in cellars or holds that maintain a temperature close to freezing.With the use of FISAIR air dehumidifiers for the production of beer, dry air is obtained continuously which holds the cellars in ideal conditions of temperature and humidity, achieving even dew points up to -25ºC, thus avoiding the condensations in the form of ice.In our website you can find additional information on the different applications, contact our experts in air humidity control and we will give you the best solution.

    Drying in the high-quality painting industry
    In an industry as important as the automotive industry, it is crucial that all processes add up, and the final product has a quality that the customer perceives as very positive. Drying in the high-quality painting industry is a very important process because it helps the car look perfect at the end of the assembly line.The use of water-based paints instead of paints with volatile organic compound bases has led to a new problem: the need for the absorption of excess water from the paint in a relatively short space of time, in order to achieve a high-quality first coat of paint. After this operation, the final lacquer coating can be applied.An inter mediate oven , where the drying takes place, is set up for this installation in a paint tunnel.Desiccant rotor operating principlesThe normal requirements for this area are 22ºC and 20%RH (3.2 g/kg at sea level). The dry air flow is determined according to the painting process, the quantity of paint applied and the time elapsed in the oven.The dehumidifier only dries exterior air (between 15 and 20% of the total flow), which is subsequently mixed with the return air.Some examples of this application are given below:3 DFRM-2900-AS-E-BF1-BF2-BC2 units, from 2004 to 2006. Seat Volkswagen. Painting lines I, II; and III. Martorell, Barcelona. 2 DFRA-2100-G-BF1 units, 2006. RENAULT, Lines A and B. Valladolid, Spain. 2 DFRA-2100-G units, 2007. DACIA-Renault in Rumania.In both first cases, FISAIR was first approved as a supplier of Seat and Renault. And also for the Renault Technological Centre in Paris.Drying in the high-quality painting industry In some cases, FISAIR dehumidifiers also provide the heat required by the tunnel, and therefore, heat the air to 65ºC, while mixing with the return air to keep the paint tunnel at 26ºC.A tunnel with lesser requirements (22ºC and 65%RH) is shown below with a subsequent air treatment unit to mix and cool. FISAIR can also manufacture the ensemble to include these units as well, but sometimes, because of their easy-assembly and transport, it is best just to send the dryer.
