Industrial Portable Film Blowing Chiller

Industrial Portable Film Blowing Chiller

An industrial portable film blowing chiller is specially designed refrigeration machine for cooling plastic film blowing machine. Its working principle is as follows: the chiller refrigerates through the compressor, cools the indoor ambient air from 40-45℃ to 10-15℃ through the built-in high-efficiency copper tube heat exchanger, and then the high-pressure centrifugal blower sends the low-temperature air through the air duct. The inner and outer air rings of the film blowing machine are used to cool the film bubble just blown out of the die head, so that the film bubble can be quickly cooled. All of these improve the thickness uniformity of the film, increase the transparency and brightness, accelerate the setting of the film, improve the physical properties of the film, and increase the output by more than 20-30%.

The film blowing chiller has a strong ability to dehumidify the air which has a large amount of condensed water during rapid cooling, keeping the sent cold air dry and low temperature, thereby improving the quality of the film.

3.2 Evaporator

The evaporator is a crucial component of film blowing chiller, as it is responsible for extracting heat from the liquid being cooled,it is located between the compressor and the expansion valve. There are three types of evaporators : stainless steel coil in water tank evaporator , 304SS stainless steel plate type evaporator.

Surface Air Cooler Used In Film Blowing Process

Surface air coolers (also known as cooling rollers or roller coolers) are usually used on film blowing machines as a cooling device to help quickly cool and solidify the molten plastic and ensure the formation and quality of the plastic film.

A surface air cooler is a roller with a special surface treatment that usually includes internal channels that can reduce the surface temperature of the roller by flowing a cooling medium (such as water or coolant) inside. The following are the main functions of the surface air cooler on the film blowing machine:

Rapid cooling: When the molten plastic passes through the mold to form a film, the role of the surface cooler is to quickly reduce the temperature of the plastic so that it solidifies quickly and maintains the desired shape and thickness.

Controlling film thickness: By adjusting the working parameters of the surface cooler, the film thickness during the film blowing process can be accurately controlled to ensure compliance with specifications.Improved production efficiency: Surface coolers enable film blowing machines to achieve faster production speeds because rapid cooling allows the film to move through the production line faster.

Reduce deformation and defects: By maintaining the correct cooling temperature and speed, surface coolers can reduce deformation, defects or surface unevenness that may occur in molten plastic during the cooling process.

The surface air cooler is an important component in the film blowing machine and plays a key role in ensuring the smooth progress of the film blowing process and high-quality film production. It provides the necessary cooling function to ensure that the film blowing machine can efficiently produce plastic film products that meet the requirements.

What’s the Difference Between Air-cooled & Water-cooled Film Blowing Chillers?

There are two types of Film Blowing chiller: one is air-cooled Film Blowing chiller ,the other is water-cooled Film Blowing chiller ;

Air-cooled Film Blowing chillers use ambient air to dissipate heat from the brewing processes. They are energy-efficient, space-saving, and less maintenance that helps save money.

Water-cooled Film Blowing chillers use water from an external water cooling tower to dissipate heat from the brewing processes. These systems are longer lifespan, Relatively quiet, and more consistent cooling performance than the air-cooled Film Blowing chiller.

How I Can Choose The Right Industrial Portable Air Cooled Blow Molding Chiller ?

There are five important chiller specifications you need consider when you choose a chiller for your application :the cooling capacity for chiller ,the voltage required for operation, the associated pump horsepower and flow rate (contact us for custom selection), refrigerant, and the evaporator type.

6.1 Calculate Right Cooling Capacity For Chiller

One of the most frequently ask about how we can know the cooling capacity for chillers.  We use KW ,Ton, But/h,Kcal/h to choose chiller cooling capacity :

1 KW=860 kcal/h ;

1 TON=3.517 KW;

1 KW=3412 Btu/h;

How to calculate right cooling capacity for your Film Blowing chillers?

Choosing the right size of a film blowing chiller is crucial for ensuring optimal performance and efficiency in your film blowing process. How to calculate the correct cooling capacity for your film blowing chiller,please see below:

▷ pls tell us the production for your film blowing machine;  

▷ how many degree of outlet water temperature from the chiller you request ;

▷ what the material for product? PE or other material ?

6.2 Power

Different countries and regions have different standards for industrial electricity, the common power supplies are 208-230V, 380-420V,440-480V,50Hz or 60Hz, 3phase.

Such in Philippines ,the power supply is 220V 60HZ 3PH , 380V 60HZ 3PH ,460V 60HZ 3PH;

in Singapore and Malaysia ,the power supply is 415V 50HZ 3PH;

in Mexico ,the power supply is 220V 60HZ 3PH;

In USA ,the power supply is 208V 60HZ 3PH;575V 60HZ 3PH;480V 60HZ 3PH and so on

6.3 Water Pump

When you decide the capacity/tonnage of the chiller, we will recommend you the suitable pump in KW,which standard water pump is about 2 bar .If you need more high water pressure , please us when you inquiry.

6.4 Refrigerant

R22, R410A, R407C, R404A, R134A are optional choices.

R22: good cooling effect, but R22 is considered a powerful greenhouse gas, so it’s forbidden in most countries.

R410A: eco-friendly, R-410A has replaced R-22 as the preferred refrigerant for use in residential and commercial air conditioners in Japan, Europe, and the United States. R-410A operates at higher pressures than other refrigerants.

R407C: a good replacement for R22, good cooling effect.

R404A: suitable for application that requires low temperature(below -10°c).

R134A: a non-flammable gas used primarily as a “high-temperature” refrigerant, suitable for air-cooled chiller working at a high ambient temperature above 50℃.

6.5 Evaporator Choose

Chillers generally have two types of evaporators: one is coil in water tank evaporator ,the other one is shell and tube evaporator with buffer tank.

Coil and tank evaporator, which has a built-in water storage tank for more convenient use,so there’s no need for extra buffer tanks. This is also our standard evaporator for chiller , if you don’t have buffer tank ,we just use this evaporator for your chiller.  

But it has a limited capacity and is not suitable for applications with larger chilled water demands.External tank’s capacity can be customized according to specific needs.

It can buffer a larger heat load, store more chilled water, but the installation will be more troublesome.

Shipping Way of Film Blowing Chillers

As a professional portable chiller supplier &exporter,we have our own shipment forwarder to arrange the shipment .Our chiller machine is with plywood packing,which prevent damage during transportation and meet export standards.There are three ways can delivery your chiller unit :

1. Ship by Air: As the chiller is with compressor ,water pump and fans ,the compressed refrigerant and oil inside the compressor is a dangerous item with the possibility of explosion , so it needs to release the compressed refrigerant before transportation. (It means that water chiller without refrigerant when choosing this shipping way. After the machine arrives at your destination, you need to add refrigerant by local professionals. The airline company also request us to provide many documents to prove that the chiller not a dangerous product. The freight cost by air is very high may be higher than the cost of chiller , So By air for delivery is not the mode of transport recommended to our customer.

2. Ship by Sea: The transportation time is longer than by air , but the freight cost is cheap ,and there is no need to add refrigerant after the equipment arrives at the destination.This shipping way is the most suitable mode of transportation for you to delivery your local port.

3.If you have your own shipment container in your other supplier in China, we can help you delivery the chiller machine to your supplier in any city of China .
