 Performance Characteristic  
 

★ The precision variable frequency blown film air cooler is designed specifically for cooling blown film machines. Working principle: The air cooler uses a compressor to cool the indoor air at 40-50 ℃ to 10-15 ℃ through a built-in exchanger, while the low-temperature air is sent to the air ring and internal cooling system of the blown film machine through a centrifugal fan. Cool the film bubbles just blown out of the mold head, rapidly cool and plasticize them, improve the thickness uniformity of the film, increase transparency and brightness, accelerate the shaping of the film, improve the physical properties of the film, and increase the yield by 10-20% or more.

★ Advantages of variable frequency blown film air cooler: high precision of air outlet temperature. Equipped with a specially designed PLC and program, as well as a professional refrigeration frequency converter, it controls the air outlet temperature to ± 0.5 ℃, making it suitable for uniform thickness control of automatic air rings. Variable frequency cold air temperature control is stable, and the film quality is good. The constant inlet air temperature of the blown film machine can reduce the frequency of worker adjustment and save labor costs.
