Pillow-Plates
Heat exchangers built by FIC using Pillow Plate technology for heat recovery can boast a long series of references in various industrial sectors. They consist of a series of Dimple Plate/Pillow Plate elements, varying in number and size according to the process parameters, enclosed in a casing of normally rectangular or circular cross-section.
They are designed for liquid/gas exchange, particularly suited to situations where plate geometry can provide clear advantages.
These exchangers are designed and built to meet the needs of a variety of markets. Available in a wide range of materials, from AISI 304 to SMO 254, from AISI 904L to SAF 2307 or LDX 2101, with operating pressures from 3 to over 80 bar and temperatures up to over 600°C.
They are designed for heat recovery systems from gases or flue gases with a high moisture content, through to Bulk Solid Heat Exchangers for the heat treatment of granular solids.
These heat exchangers can be found in all kinds of industries: paper, textile, food, chemical, galvanic and many others.
Here are a few typical cases in which the heat exchangers developed by FIC are particularly useful:
- when there are extractions of warm air with a medium or high relative humidity content, with Dimple Plates it is possible to obtain high heat transfer coefficients in the condensation conditions typical of these processes (for example, in paper mills downstream of the air-air exchange section);
- when the gas flows of certain production processes contain large quantities of dust or fibres, since the constructive geometry of FIC exchangers allows easy and rapid cleaning, without the need for costly stoppages and maintenance (e.g. in cement works or wood treatment plants);
- when it is necessary to keep the pressure drop on the extraction side as low as possible (to reduce fan energy consumption and investment costs);
- when it is necessary to condense components that pollute or cause environmental problems (odours), as the condensation process is greatly facilitated by the geometry of the Pillow Pate (e.g. animal feed production plants).
