What Are The Main Components Of 20 Ton Industrial Chiller Unit For Grinding Miller

3.1 Compressor

The compressor is the key mover in Industrial chiller unit because it produces pressure variations to stir the refrigerant around.

For 20 Ton 70KW Industrial Chiller Unit For Grinding Miller, which is with TWO unit 12.5HP Panasonic /Danfoss brand 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.

Panasonic Compressor

3.2 Evaporator

The evaporator is a crucial component of industrial 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 : coil in water tank evaporator , shell and tube evaporator, 304SS stainless steel plate type evaporator.

Coil in SS Water Tank Evaporator

SS Plate Type+ 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 , please 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 .

Water Pump

High Pressure Water Pump

3.4 Condenser

The condenser for industrial air cooled 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.

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 20 Ton Industrial Chiller Unit For Grinding Miller for Your Application?

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;

There is also a formula to calculate the cooling capacity for chiller:.

Cooling Capacity(kw)= Flow Rate(m3/h)*Temp Change(T1-T2)/0.86

Heat Load= C(specific heat)* M(quality output per hour )*Temp Change(T1-T2)

Oversize the chiller by 20% Ideal Size in KW = KW x 1.2

Noted : T1:Incoming Water Temperature (℃)      T2:Required Chilled Water Temperature(℃)    


For example, what size of chiller is required to cool 10m³ water from 35°c to 15 °c in 1 hour?

Temperature Differential = 35℃-15℃=20℃

Water Flow Rate = 10 m³/hour

Cooling Capacity in KW = 10 x 20 ÷ 0.86 = 232 KW

Oversize the chiller = 232 x 1.2 = 278.4KW

278.4 kw cooling capacity for chiller is required.

5.2 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

5.3 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.

5.4 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℃.

5.5 Evaporator Choose

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

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.

Shell and tube type evaporator, which requires an additional water buffer tank to connect .

Industrial Applications of Industrial Chiller Unit

Industrial chiller unit is very popular refrigeration system that can provide steady and reliable water cooling sources for both industrial and commercial usage,which is also widely used in plastic industry,food industry ,chemical industry and other industrial.

6.1 Plastic Industry

Industrial chillers are also widely used in plastic processing and plastic industry including plastic injection molding, plastic extrude, and extrusion lines, blowing molding machines.

The function of using an Industrial air cooled scroll chiller is to provide the cooling water flow rate for cooling the plastic mold temperature down to make sure the product quality and production efficiency.

Shipping Way of 20 Ton Industrial Chiller Unit For Grinding Miller

As a professional industrial air cooled process 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 .
