Stainless Steel Cover Air cooled Corrosion Resistant Chiller

Stainless Steel Cover Air cooled Corrosion Resistant Chiller

Air-cooled corrosion resistant chiller with stainless steel cover is an industrial air-cooled chiller widely used in the food ,medical and pharmaceutical industry. This is a friendly custom chiller.

Stainless steel chiller units are available in air-cooled and water-cooled types: their working principles are actually the same as industrial chillers. At the beginning, the compressor sucks in the low-temperature and low-pressure refrigerant gas after evaporation and refrigeration, and then compresses it into high-temperature and high-pressure gas and sends it to the condenser; after the high-pressure and high-temperature gas is cooled by the condenser, it condenses into normal temperature and high-pressure liquid; the normal temperature and high-pressure liquid flows into the thermal expansion When the valve is closed, it is throttled into low-temperature and low-pressure wet steam, flows into the evaporator, absorbs the heat of the frozen water in the evaporator, and lowers the water temperature; the evaporated refrigerant is sucked back into the compressor and repeats the next refrigeration cycle. The difference between air cooled and water cooled lies in the different methods of heat dissipation. The stainless steel cover air cooled corrosion resistant chiller uses aluminum fin+fan as condensers,they absorb heat from process water, and the heat is then transferred to the air around the chiller unit. The water-cooled stainless steel corrosion resistant chiller requires the installation of a water cooling tower to bring heat to the shell and tube condenser, and then a water pump brings the water to the cooling water tower for circulation back and forth. Due to the principle of high temperature and high pressure when the compressor works, the ambient temperature in summer is relatively high, and water-cooled chiller has a better effect, but it requires a cooling tower. The air-cooled type chiller is flexible to assemble and easy to install. It no need a cooling tower, is suitable for use in water-scarce areas or occasions that need to be moved.

What is the Difference Between Standard Industrial Air Cooled Chiller and Industrial Water Cooled Chiller?

Industrial Air-cooled and industrial water-cooled chillers are both types of chillers used for cooling applications in various industries.

The main difference between industrial air cooled chiller and industrial water cooled  chiller is condenser :

The condenser of an industrial air cooled chiller is cooled by the ambient air,which the heat generated during the cooling process is dissipated into the surrounding air;

Industrial Water Cooled Chiller with a shell and tube water-type condenser that is attached to a cooling tower and is typically used in medium and wide installations where water is available.So industrial Water cooled chiller need connect with water cooling tower and water cooling pump outside , the installation is more trouble than air cooled screw chiller .

But if your ambient temperature is very high above 50℃,we suggest you use industrial water cooledchiller ,as industrial air cooled chiller may consume more energy to achieve the same cooling capacity due to the limitations of air as a heat exchange medium and industrial water cooled chiller uses constant water source for more stable and efficient heat dissipation,so in high ambient temperature , industrial water cooled chiller is more energy-efficient and better choice for your application .

How I Can Choose The Right Stainless Steel Cover Chiller For Your Application?

There are SIX 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.

7.1 Calculate Right Cooling Capacity For Chiller

Chiller sizes are traditionally listed according to Ton,KW, But/h,Kcal/h. Tons does not refer to the actual weight of the chiller, but instead is a historical reference to a time when blocks of ice were harvested for cooling. Just like engines are still measured according to “horsepower”, the term “tons of refrigeration” stuck around：

1 KW=860 kcal/h ;

1 TON=3.517 KW;

1 KW=3412 Btu/h;

7.2 Types of stainless steel chiller system?

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

Water cooled chiller needs a separated water cooling tower and water cooling pump ,if you don‘t have existing water cooling tower,we suggest you use air cooled chiller; But if your ambient temperature is very high above 55℃ ,we suggest you use water cooled chiller , as it is easier to dissipate heat for water cooled chiller with water cooling tower.

But Most customers use air cooled stainless steel chiller ,which is more easily install and save space.

7.3 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

7.4 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.

7.5 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℃.

7.6 Evaporator Choose

Chillers generally have two types of evaporators: one is coil in water tank evaporator ,the other one is shell and tube evaporator 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 Stainless Steel Cover Air Cooled Corrosion Resistant Chiller

As a professional custom 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 .
