The air-cooled screw chiller is a screw chiller that uses fans to dissipate heat. The installation environment it needs must be open and easy to circulate, so that this operation will not affect the cooling effect of the air-cooled screw chiller .

 

Therefore, we should understand some common faults of air-cooled screw chillers and some troubleshooting methods:

 

1. The fan noise of the air-cooled screw chiller is too loud

 

Bearing component wear/excessive clearance: If it is worn, it should be replaced in time, and if the clearance is too large, it can be directly adjusted to a suitable position;

 

The speed is too high: it can be improved by reducing the speed, if it is not solved, replace the fan;

 

2. The temperature rise of the motor of the air-cooled screw chiller fan is too high

 

The flow exceeds the rated value: the valve needs to be closed at this time;

 

Motor or power supply problems: find out the reasons for the motor and power supply;

 

3. The bearing temperature of the air-cooled screw chiller fan increases

 

The fan shaft and the motor shaft are different: they need to be adjusted to be concentric;

 

Bearing damage: need to replace a new bearing, or directly contact the chiller manufacturer to replace it.

 

Insufficient lubricating oil (grease) or poor quality: If the lubricating oil is not enough, the company should fill it up to the required part; if there is a quality problem, it is necessary to clean the bearing or replace the more qualified lubricating oil (grease);

 

4. The air output of the air-cooled screw chiller fan is too small:

 

Blockage of air inlet, outlet and pipe: check and remove the blockage;

 

Insufficient valve opening, speed, and belt slack: you can check the bearing by adjusting the valve opening to a proper opening, tightening and replacing the belt, and checking the voltage.

 

Check that the connection between the impeller and the shaft is loose, which can be eliminated by direct prohibition; if the gap between the impeller and the air inlet is too large, it should be adjusted to a suitable gap.

 

The fan of the air-cooled screw chiller is equivalent to the cooling tower cooling system of the water-cooled chiller. If the heat dissipation effect is not good, the cooling capacity of the air-cooled screw chiller is absolutely insufficient, which directly affects the company’s refrigeration Water demand. Therefore, we need to maintain and maintain our chillers in a timely manner.

What caused poor refrigerating efficiency?

Sometimes when we use a chiller, but the temperature could not be lower, or After cooling down to a certain temperature, it won’t go down anymore. Let's talk What caused the poor refrigerating efficiency ?

1. Refrigerant leakage

[fault analysis] After the refrigerant leak in the system, the cooling capacity is insufficient, the suction and exhaust pressure are low, and the expansion valve can hear much larger intermittent “squeak” air flow than usual.The evaporator is not frosted or with a small amount of frosting. If the expansion valve hole is enlarged, the suction pressure remains unchanged.After the shutdown, the equilibrium pressure in the system is generally lower than the saturation pressure corresponding to the same ambient temperature.

2. Too much refrigerant is filled after maintenance
[fault analysis] When the refrigerating dose filled in the refrigeration system after maintenance exceeds the capacity of the system, the refrigerant will occupy a certain volume of the condenser, reduce the heat dissipation area, and reduce its refrigeration efficiency. Generally, the suction and exhaust pressure are higher than the normal pressure value, the evaporator is not frosted, and the temperature in the warehouse is slow.

3. Air in the refrigeration system

[fault analysis] The air will reduce the refrigeration efficiency in the refrigeration system. The prominent phenomenon is the increase of suction and exhaust pressure (but the exhaust pressure has not exceeded the specified value). The temperature of the compressor at the inlet of the condenser is significantly increased.

4. Low compressor efficiency

[fault analysis] The low efficiency of refrigerating compressor refers to the reduction in the response of refrigerating volume due to the decrease of the actual exhaust volume under the condition that the working condition remains unchanged.This phenomenon usually occurs on compressors that have been used for a long period of time, with large wear and tear, large clearance of all components, and decreased sealing performance of air valves, which results in the decrease of actual air discharge.

5. The surface of evaporator is frosted too thick
[fault analysis] Long-term use of cold storage evaporator should be regularly defrosted. If the frost is not defrosted, the frost layer on the evaporator tube becomes thicker and thicker. When the whole pipeline is encased in transparent ice, the heat transfer will be seriously affected, causing the temperature in the reservoir to fall below the required range.

6. There is frozen oil in the evaporator pipeline
[fault analysis] During the refrigeration cycle, some frozen oil remains in the evaporator pipeline. After a long period of use, a large amount of oil remains in the evaporator, which will seriously affect its heat transfer effect and lead to poor refrigeration.

7. The refrigeration system is not smooth
[fault analysis] Because the refrigeration system is not clean, after several hours of use, the dirt is gradually silted up in the filter and some mesh holes are blocked, resulting in the reduction of refrigerant flow and affecting the refrigeration effect.
In the system the expansion valve, the compressor suction nozzle at the filter screen also has a small plug phenomenon.

8. The filter is blocked
[fault analysis] When the desiccant is used for a long time, it becomes paste to seal the filter, or the dirt gradually accumulates in the filter, causing blockage.

9. Leakage of refrigerant in the expansion valve sensible temperature package
[fault analysis] After the leakage of the temperature sensor in the expansion valve’s temperature sensor package, two forces under the diaphragm push the diaphragm upward. It is the valve hole closed.

10. Cold air cooling condenser has poor cooling effect in the cold storage
[fault analysis]
⑴The fan is not on.
⑵Parliamentary fan motor damaged.
⑶Torque fan reverse.
⑷high ambient temperatures (40 ℃ above).
⑸Flow of condenser cooling fins blocked by oil and dust.

11. The cooling effect of water-cooled condenser is poor
[fault analysis]
⑴The cooling water valve is not opened or opened too small, and the inlet pressure is too low
⑵Potassium water regulating valve fails.
⑶The scale on the wall of the condenser pipe is thicker.

12. Too much refrigerant is added into the system
[fault analysis] Too many refrigerants lead to a significant increase in the exhaust pressure, exceeding the normal value.

13. Residual air in the system
[fault analysis] The air circulation in the system will lead to excessive exhaust pressure, high exhaust temperature, hot exhaust pipe, poor refrigeration effect, the compressor will operate soon, and the exhaust pressure will exceed the normal value.

14. Stop when the suction pressure is too low
[fault analysis] When the suction pressure in the system is lower than the set value of the pressure relay, its contact action will cut off the power supply.

15. The temperature controller is out of control
[fault analysis] The thermostat fails to adjust or the temperature sensor package is improperly installed.

16. Sudden stop caused by other reasons
[fault analysis] In the process of use and maintenance, it is often necessary to open, close the exhaust, inhale, and store the liquid, etc.

Industrial chillers are one type of chillers, and chillers can be divided into air-cooled chillers and water-cooled chillers.

Water chiller is a kind of water cooling equipment, which can provide constant temperature, constant current and constant pressure cooling equipment. The principle of the chiller is to inject a certain amount of water into the internal water tank of the machine, and the water is cooled by the chiller refrigeration system, and then a water pump inside the machine injects low-temperature frozen water into the equipment that needs to be cooled, and the chilled water will heat the internal heat of the machine. Take it away and return the high-temperature hot water to the water tank to cool down again. In this way, it is circulated and exchanged and cooled to achieve the effect of cooling the equipment.

In industrial applications, chilled water or other liquid cooling pumps are passed through processes or laboratory equipment. Industrial chillers are used in various industries to control the cooling of products, mechanisms and factory machinery. They are commonly used in injection and blow molding in the plastics industry, metal processing cutting oils, welding equipment, die-casting and machining, chemical processing, pharmaceutical formulation, food and beverage processing, papermaking, cement processing, vacuum systems, X-ray diffraction, electric power Supply and power stations, analytical equipment, semiconductors, compressed air and gas cooling. They are also used to cool high heat energy, such as MRI machines and laser specialized engineering projects, and in hospitals, hotels and campuses. The chillers for industrial applications can be centralized, and each chiller can meet multiple needs for cooling, or be dispersed in each application or device with its own chiller. Each method has its advantages. It may also have a combination of central and decentralized chillers, especially when the cooling requirements are the same for certain applications or use points, but not all.

Distributed chillers have a small area (cooling capacity) usually from 0.2 tons to 10 tons. Central chillers generally have a capacity ranging from 10 tons to hundreds or thousands of tons.

Chilled water is used to cool and dehumidify the air in large-scale commercial, industrial and institutional alliance (CII) facilities. The chiller can be water-cooled, air-cooled, cooled or evaporatively. The use of water-cooled chillers is incorporated into cooling towers, which improves the cooling' thermodynamic efficiency compared to air-cooled chillers. This is due to the high temperature or the wet bulb temperature of the nearby air, rather than repelling the high, sometimes much higher, dry bulb temperature. Evaporatively chillers provide better efficiency than air cooling, but lower than cold water.

Several aspects of the chiller should be paid attention to:

1. Selection of model size of chiller for injection molding machine

When used as a mold cooling of an injection molding machine, it can be calculated according to the injection volume of the injection molding machine. Generally, a 1HP chiller is used for every 6 ounces of injection volume. For example, the customer’s factory is 100T (5.5OZS)×3; 150T(12OZS)×4 units; 200T(23OZS)×3 units; the required chiller size is (5.5×3+12×4+23×3)/6=22.25, that is, a 25HP chiller. When used for cooling of other equipment, it depends on the specific flow rate of the cooling water circulation.

2. Selection of the insulation water tank and water pump of the chiller

Sometimes according to the actual situation of the customer's factory, the box-type chiller may also require an external pump. At this time, the additional pump model must have the same power as the pump that comes with the chiller. If the 10HP box-type chiller comes with a pump power of 2HP, when the pump is added, it must also be 2HP.

3. The temperature of the return water of the chiller should not be higher than 40 degrees. The higher the return water temperature, the greater the damage to the compressor.

Chillers are divided into air-cooled chillers and water-cooled chillers. The working principle diagram of air-cooled chillers is as follows

Working Principle of air-cooled chiller

The air-cooled chiller uses a shell and tube evaporator (or tank with coil) to exchange heat between water and refrigerant. The refrigerant system absorbs the heat load from the water and cools the water to produce cold water. The heat is brought to the finned condenser through the action of the compressor. Then it is lost to the outside air by the cooling fan (wind cooling)

Features of air-cooled chillers：

1、The air-cooled chiller does not need to be installed with a cooling water tower and is suitable for environments with poor impurities. (It is easy to mix impurities in the cold water tower, and the dust will block the cooling water circulation loop, causing the cooling capacity to drop).

2、Air-cooled chillers are most suitable for areas with poor water quality, and can save other accessories for chillers.

3、With a large-capacity condenser, it can be easily operated even in heat.

4、Minimize floor space and easy installation

5、The air-cooled chiller adopts a top-out air design.

The working principle diagram of the water-cooled chiller is as follows:

Schematic diagram of the principle and flow of water-cooled chillers

The water-cooled chiller uses a shell and tube ( or tank with coil ) evaporator to exchange heat between water and refrigerant. The refrigerant system absorbs the heat load of the water and cools the water to produce cold water. The heat is brought to the shell and tube condenser through the action of the compressor. The refrigerant exchanges heat with the water, so that the water absorbs the heat and then takes the heat out of the cooling tower through the water pipe to dissipate (water cooling)

Features of water-cooled chillers:

1. High-quality compressors are the heart of industrial chillers (brand-new original compressors from Europe, America and Japan, with built-in safety protection, low noise, power saving and durability).

2. The box-type evaporator has a built-in automatic water replenishment device, which saves the need for the expansion water tank in the engineering installation to facilitate installation and maintenance, and is suitable for special occasions such as large temperature difference and small flow.

3. The water-cooled condenser is made of the latest high-efficiency externally threaded copper pipe, with large heat dissipation and small size. Using the latest CAD/CAM processing technology, with CNC machining center to complete the production, compact structure, high reliability, beautiful appearance, high efficiency and energy saving.

4. Industrial chiller unit configuration: equipped with a single-chip control system, built-in compressor dryer filter and expansion valve, maintenance hand valve interface and other devices, to ensure the reliable and safe operation of the machine to facilitate maintenance and repair.

5. The multi functional operation panel of the industrial water chiller is equipped with ammeter, control system insurance, compressor switch button, water pump switch button, electronic temperature controller, various safety protection fault lights, unit start-up and operation indicator, simple operation and convenient use . Industrial chiller unit configuration: equipped with a single-chip control system, built-in compressor drying and expansion valve, maintenance hand valve interface and other devices, to ensure the reliable and safe operation of the machine, and facilitate maintenance and repair.

In industrial production, stable process cooling isn’t just a support function — it’s often the difference between smooth operation and costly downtime. At OUMAL Refrigeration Machinery Co., Ltd, we’ve worked with customers across injection molding, extrusion, thermoforming, and more. Over time, one thing has become clear: choosing the right chiller matters.

Not All Cooling Needs Are Created Equal
Different industries — even different machines — have very different cooling requirements. For example, a customer running a small injection molding line may only need a compact 8 ton chiller to maintain mold temperatures within a tight range. These chillers are space-efficient and offer precise control, making them a practical choice for localized cooling tasks.

On the other hand, when the scale increases or when multiple machines share a cooling circuit, something like a 15 TR chiller tends to be a better fit. We’ve seen these used successfully in mid-sized production lines where reliability and steady performance are non-negotiable.

For large plants, especially those operating around the clock, a 100 ton water cooled chiller can provide both capacity and energy efficiency. Water-cooled systems require more infrastructure — including cooling towers and proper piping — but in return, they offer stable performance in high ambient environments and over long production runs.

Built for Industry, Backed by Experience
What sets OUMAL apart is not just the equipment itself, but the way we build around customer needs. Our manufacturing team can handle a wide range of options and customizations, which means the chiller you receive isn’t off-the-shelf — it’s made to work the way you do.

We’ve served customers in over 20 countries, including the US, Australia, Saudi Arabia, Vietnam, and Brazil. The variety of applications we’ve supported — from blown film to compound mixing — gives us the insight to ask the right questions before making a recommendation. Our goal is always to match cooling performance with process demand, rather than over- or under-sizing.

Long-Term Value Comes from the Right Start
One thing we often remind our partners: a properly selected chiller does more than control temperature. It protects your equipment, shortens your cycle times, and helps maintain product consistency. That’s especially important in processes where a few degrees can mean the difference between a good batch and scrap.

Whether you’re starting with a single machine or upgrading an entire line, OUMAL is ready to help you choose wisely — whether that’s an 8 ton, 15 TR, or 100 ton water cooled chiller.

When someone new joins our engineering team, one of the first questions they usually ask is: “So what’s the difference between air cooled and water cooled chillers—and which one’s better?”

It’s a good question. And after installing, maintaining, and even troubleshooting both systems in dozens of customer factories, here’s how we usually explain it.

Let’s Start with the Basics

An air cooled chiller is essentially a cooling unit that uses ambient air to remove heat from a circulating liquid—usually water or a water-glycol mix. It's often used to keep production equipment or buildings at a stable temperature.

There’s no need for a cooling tower or a complex water pipeline. It uses built-in fans to get the job done.

This setup is widely chosen in:

• Injection molding plants

• Food packaging lines

• Laser processing workshops

• HVAC systems for commercial buildings

If you’ve got space outside and want to avoid dealing with water quality issues, air cooled is probably the better call.

What’s Inside the Unit?

Rather than listing textbook components, here’s what we see under the cover of atypical air cooled water chiller we ship:

• A compressor that acts like the system’s engine

• An evaporator that draws heat out of your process water

• A condenser with aluminum fins, cooled by strong fans

• An expansion valve to adjust refrigerant pressure

• A control panel—the brain of the system

Some models include water pumps and tanks. Others are modular—you can connect them to existing infrastructure.

Here’s How It Works (Simplified)

Let’s say you’re using a CNC machine that heats up during operation. Here’s how the air cooled chiller steps in:

1. The warm water comes back from the CNC.

2. It enters the evaporator inside the chiller.

3. The refrigerant in the evaporator absorbs that heat and turns into a gas.

4. The gas gets compressed—its temperature and pressure rise sharply.

5. That hot gas goes through the condenser. Fans blow outside air across coils, removing the heat.

6. The refrigerant turns back into a liquid, and the cycle repeats.

Your machine keeps running cool—and you don’t need a water tower or much operator attention.

Why Do Customers Choose Air Cooled Units from Us?

Some of our long-term clients choose air cooled chiller systems for one reason: they just work.
Even without an in-house technician, these systems are straightforward to install, easy to control, and rarely break down when used correctly.

Clients also appreciate that we offer:

• Tailored sizing based on actual load

• Remote monitoring options

• Short lead times, even for custom orders

• Reliable after-sales support (yes, even overseas)

As a practical air cooled chiller supplier, we’re not here to sell what’s biggest or most expensive—we help customers find what runs stably for years.
