It forms the heat transfer surface which is needed in heat exchange of water and air in cooling towers. PVC Folio Plaques are formed under vacuum. It is formed as bales so that it can be pasted later. It is used in low temperature process waters (maximum 55°C). It is preferred in such facilities where the water is clean (purged from dust, dirt and lime). Its performance is much better than other fill types because its heat exchange surface is more. It is produced as CF- 12, CF- 19, CF- 30, CF-M and CF-O types. CF-30 type fill is successfully being used at purification facilities, especially in biological purification facilities. CF-O type fill is being used in cross flow cooling towers.
