The cooling batteries series BCA are combined within groups and elements of refrigeration for the process air cooling control of film extruders and IBC (Internal Bubble Cooling). It improves the speed of extrusion by circulating cold air inside the bubble and cooling the film faster. They are available in configuration with and without built-in centrifugal fans (BCA and BCA / F) and are offered in modular and expandable versions.
In the solid structure in painted steel, the cooling battery BCA includes a drop separator, suitably sized inlet and outlet air channels, 3-way thermostatic valve for air outlet temperature control, condensation collection and drainage.
The heat exchangers are made by copper pipes expanded in aluminum fins placed on a sturdy galvanized steel. A number of fans, proportional to the power required, allows to facilitate the air / fluid exchange.
