Industrial Portable Extrusion Chiller

Industrial Portable Extrusion Chiller

The industrial portable chiller for cooling the extruder is called an extrusion chiller or plastic extrusion cooling system which a cooling device that can provide constant temperature, constant flow and constant pressure.Since extruders are mainly used for various extruded plastic products, such as PE, PP, PVC, ABS, etc., the high temperatures generated during the production process will cause difficulty in demoulding and slow molding, so a chiller is needed to provide low-temperature circulating chilled water. (5-30℃) to the extruder to shorten the cooling time and improve product quality.Extrusion chiller is made of compressor, air/water-cooled condenser, water tank, evaporator, water pump, microprocessor, power supply, and protecting devices. Its working principle is to first inject a certain amount of water into the water tank of the machine, cool the water through the refrigeration system of the industrial refrigerator, and then send the low-temperature cooling water to the equipment that needs cooling through the water pump. When the temperature of the chilled water in the refrigerator increases, The heat is then taken away and returned to the water tank for cooling. The cooling water temperature can be automatically adjusted according to requirements, which can save water for long-term use. Therefore, it is a standard energy-saving refrigeration equipment.

What Are The Main Components Of Industrial Portable Extrusion Chiller ?

3.1 Compressor

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

From 2 ton to 50 ton extrusion chiller , which is with Panasonic /Danfoss brand scroll compressor, using R410A/R407C/R134a refrigerant,this brand compress is with high refrigeration efficiency,low noise ,energy saving,environmental protection and durability,safety and stability.

Above 30 Ton extrusion chiller ,which can use Hanbell/Bitzer screw compressors ;

3.2 Evaporator

The evaporator is a crucial component of extrusion 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 , shell and tube evaporator.

SS Coil in SS Water Tank Evaporator

Shell and Tube Evaporator

3.3 Water Pump

The water pump is designed to increase the pressure and the flow of the chilled water in a closed space.

the water pressure water pump for chiller is about 2 bar , but if you need more higher water pressure , pls tell us when you inquiry .For example ,when you use chillers for cooling bottle blowing machine ,the water pressure for water pump need about 4 bar .

High Pressure Water Pump

3.4 Condenser

The condenser for portable air-cooled extrusion chiller 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.

Aluminum fin+fan Condenser

The condenser for industrial water cooled extrusion chiller is shell and tube ,with the internal copper tubes employing an outer thread embossing process.This design effectively enhances the heat exchange efficiency between the refrigerant and water during the process. Compared to traditional smooth copper tubes, the outer thread embossing process increases the surface area of the copper tubes, thereby expanding the contact area for heat exchange and improving the thermal conductivity of the condenser. This optimization design allows the condenser of the water-cooled chiller to transfer heat from the refrigerant to the water more rapidly and consistently, enabling the water to carry away the heat.

3.5 Controller Panel

Tongwei chillers use precision digital temperature controller, it RS485 communication port，which can do remote monitoring and control. Simple operation, low failure rate, high safety factor, easy installation.

How I Can Choose The Right Portable Extrusion 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.

5.1 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;

 ▪ Tell us the weight (KG) of material per hour being processed.

 ▪ Tell us the material such as.polyethylene or polypropylene or Polystyrene or PVC

 ▪ How many degree for inlet and outlet water temperature

5.2 Types of Extrusion chiller system?

There are two types of chiller :Air Cooled Extrusion Chiller and Water Cooled Extrusion Chiller.

Many customer factories are equipped with water cooling towers. In this case, it is better to choose a water-cooled extrusion chiller. The water-cooled extrusion chiller uses a cooling tower to dissipate heat, and the cooling stability is higher; if there is no cooling water tower, the cooling power of the chiller is low, and it is recommended to use an air-cooled chiller; users with higher cooling power (such as 50hp 60hp chillers) should choose water-cooled extrusion chiller with cooling tower for cooling

5.3 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

5.4 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.

5.5 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℃.

5.6 Evaporator Choose

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

We must confirm whether the customer's extruder has an open water tank. If so, when choosing a chiller, the shell and tube type or plate type should be selected instead of the tank coil evaporator. If there is no sink or pool, we should choose coil in water tank evaporator.

Shipping Way of Industrial Portable Extrusion Chiller

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 .
