Industrial Air Cooled Chiller

Blown Film Cooler: High Performance Chilled Air Solutions

1.What Is Blown Film Cooler?

A blown film cooler is a specialized type of refrigeration machine designed for use in the film blowing process. It is a cooling system that provides controlled and precise cooling air to the extrusion and forming components of a film blowing machine. 

Maintaining the correct temperature is critical for achieving the desired product quality, consistency, and structural integrity. If the plastic material is too hot or too cold during the molding process, it can lead to defects in the final product. The Film Blowing chillers help ensure that the plastic material is at the optimal temperature for forming the desired shape.

A Film Blowing chiller is an essential part in the Film Blowing process, which helping to regulate temperatures and improve the quality of the final plastic products.

2.Why Need Air Cooler Used in Blown Film Process?

Blown film cooler, also known as bubble cooler, is a vital component in the blown film extrusion production process. 

During blown film extrusion, molten plastic is forced through a circular die, forming tubular bubbles of plastic. The bubbles are then cooled and stretched to achieve the desired film thickness and properties.

The blown film cooler is responsible for rapidly cooling the extruded plastic bubbles. This is important as it helps maintain the desired performance and quality of the film. Cooling is achieved by flowing air over the surface of the bubbles. This airflow helps solidify the molten plastic, making it suitable for further processing or winding onto rolls.

3.What Are The Main Components of Film Blowing Cooler?

3.1 Compressor

The compressor is the key mover in air cooler because it produces pressure variations to stir the refrigerant around.

From 1/2HP(1/2 Ton) to 60HP(5oTon) Film Blowing cooler, which is with Panasonic or Danfoss brand Scroll compressor .

3.2 Evaporator

The evaporator is a crucial component of air-cooled water chiller, as it is responsible for extracting heat from the liquid being cooled,it is located between the compressor and the expansion valve. The evaporator for air cooler is:Low noise centrifugal fan.

3.3 Condenser

The condenser for air-cooled Film Blowing cooler is equipped with efficient cross-seam fins and female threaded copper tubes for high heat exchange efficiency and good stability.Its function is to cool down the refrigerant steam released from the compressor into a liquid or gas-liquid mixture.
