Cooler sizing and maintenance can have a big impact on the efficiency of a blown film manufacturing process.
Blown film coolers are used to produce bags, liners and industrial, barrier, stretch, laminated, agricultural and construction type films. Integral pieces of the blown film equipment, these coolers provide uniform cool air to the internal and external film bubble to change the plastic from a molten to a solid state. They are used in conjunction with a blower and a chilled water supply. The blower provides ambient air at a specific static pressure, moving it through the blown film cooler and into the air ring. The chilled water supply enters the system, absorbs heat from the ambient air and then is returned to the cold-water source. The proper sizing, control, startup procedures and maintenance are imperative to ensure that all of these components function correctly and efficiently.
