Innovative features and user-friendly controls help you maintain reliable operations and superior system performance.

Warehouse Cooling Problems

Scaling Issues

You often encounter scaling as one of the most common problems in warehouse cooling systems. Scale forms when minerals like calcium and magnesium deposit on heat exchange surfaces. This buildup restricts airflow and reduces cooling efficiency. You may notice temperature regulation problems and high humidity, which can make it difficult to maintain a comfortable working environment. The presence of dissolved minerals, changes in water temperature, and variations in pH levels all contribute to scaling. Calcium carbonate is the most frequent type, resulting from natural water sources. Neglecting descaling leads to corrosion and increased energy consumption. Regular descaling helps reduce humidity levels and keeps your system running efficiently.

Corrosion Risks

Corrosion poses a serious threat to warehouse cooling systems. You face general corrosion, which affects metal surfaces uniformly, and localized corrosion, such as pitting and cavitation, which can quickly damage components. Galvanic corrosion occurs when different metals, like aluminum and copper, connect in the system. Poor water quality, high oxygen content, and improper pH levels accelerate corrosion. Corrosion increases energy consumption, sometimes by up to 30%, and shortens equipment lifespan. You may need costly repairs or even system overhauls. Safety risks also rise, as overheating and system failures can threaten indoor air quality and worker health.

Biofouling Challenges

Biofouling creates additional warehouse cooling problems. Microbiological fouling results from bacteria, fungi, algae, and even larger organisms like barnacles. Particulate fouling happens when organic matter and minerals accumulate in the system. Hydrocarbon fouling can also affect cooling performance. Biofouling forms a slime layer on heat transfer surfaces, acting as an insulator. This layer reduces heat exchange efficiency, forcing your system to use more energy to maintain proper cooling. High humidity and inefficient air distribution worsen biofouling, making it harder to improve air circulation and ventilation. Large warehouse fans may help, but you must address biofouling to ensure optimal airflow and maintain indoor air quality.

Scaling Prevention

You face scaling when minerals like calcium and magnesium build up on heat exchange surfaces. The industrial air cooled screw chiller uses advanced technology to help you prevent this problem. The OMC-100ASH model features a semi-hermetic screw compressor that maintains stable water temperatures. This stability reduces the risk of mineral deposits forming inside your system. The chiller’s shell and tube evaporator design improves water flow, which helps keep minerals suspended and away from critical surfaces.

These chillers are often outside. Sometimes, they go on rooftops. Water-cooled chillers use less space inside. But you need extra room for cooling towers. You also need space for pipes.

Tip: If you do not have much outdoor space, water-cooled chillers can fit inside your building.

Installation Complexity

Check how hard it is to set up each chiller. Air-cooled chillers are easier to install. You can put them outside. You do not need extra parts. Water-cooled chillers are harder to set up. You must add cooling towers. You need pumps and pipes too. This takes more time and work.

Some problems can happen:

• Air-cooled chillers are big and heavy. Putting them on a roof can be hard.

• Water-cooled chillers need more pipes and cooling towers. This costs more money and time.

If you want a fast and easy setup, pick an air-cooled chiller. If you want better efficiency and have more time, water-cooled chillers may be best.

Environmental and Noise Impact

Water Usage and Sustainability

When you pick a chiller, think about water use. Water-cooled chillers need cooling towers. These towers use a lot of water. Water is lost by evaporation, drift, and blowdown. If you raise the cycles of concentration, you can save water. This can lower water use by up to 20%. Air-cooled chillers do not use water for cooling. They use air instead, so water use is low.

• Water-cooled chillers need lots of makeup water each year.

• More cycles of concentration in towers help save water.

• Air-cooled chillers do not need water for cooling.

Water-cooled chillers can affect the environment a lot. They use much water, which is a problem where water is rare. If you do not treat the water before letting it go, it can hurt plants and animals nearby. These chillers also use power, which can cause more greenhouse gases.

Noise Levels

Noise is important when you put in a chiller, especially in cities. Air-cooled chillers make noise from fans, pumps, and compressors. Water-cooled chillers are quieter. Most water-cooled chillers run at 55 to 75 decibels. A well-kept chiller in a medium building might be 60 decibels. This is as quiet as gentle rain.

• Air-cooled chillers make noise from fans and moving parts.

• Water-cooled chillers are quieter and good for quiet places.

Local rules often limit how loud chillers can be. The World Health Organization says loud noise can harm your health. If your chiller is too loud, you could break city rules. This can upset neighbors and make work less comfortable for workers.

Maintenance Needs for Air Cooled Screw Chiller and Water-Cooled Chiller

Routine Maintenance

You need to take care of your chiller often. Both air-cooled and water-cooled chillers need regular checks. You should look at refrigerant levels a lot. If you find leaks, fix them fast. Clean the evaporator coils every six months. This helps the chiller work well. Test the electrical parts and change any broken ones. Lubricate moving parts so they last longer. For water-cooled chillers, watch water flow and pressure. Check oil quality and levels to stop breakdowns.

Air-cooled chillers need more care. Water-cooled chillers need less checking, but you must treat water and clean cooling towers. How often you do maintenance depends on how much you use the chiller, its age, and where it is.

Long-Term Reliability

You want your chiller to last a long time. Air-cooled chillers work for 15 to 20 years. Water-cooled chillers last 20 to 30 years. Problems happen from dirt, clogs, electrical issues, or not doing maintenance. If you keep up with care, you can stop most problems. Water-cooled chillers need extra water treatment and tower cleaning. Air-cooled chillers need coil cleaning and electrical checks more often.

• Main reasons chillers break:

  • Dirt buildup

Air, as a cooling medium, cannot absorb as much heat as water, so the system may use more electricity to achieve the same cooling effect.

Noise can be another concern. Air-cooled chillers use large fans to move air across the condenser coils. These fans can generate noticeable noise, especially when the chiller operates at full capacity. If your facility is located near offices or residential areas, you may need to plan for noise reduction measures.

Key Comparison Factors

Cost

You need to consider both initial and ongoing costs when choosing a chiller. Water cooled screw chillers usually require a higher upfront investment. You pay for the chiller itself, a cooling tower, and extra piping. Installation takes longer because you must set up a continual water source and allocate space for additional equipment. Air-cooled chillers cost less to install. You can place them outdoors and avoid the expense of a cooling tower. Over time, water cooled screw chillers may save you money through lower energy bills, especially in large facilities. Air-cooled chillers often have higher operating costs in hot climates due to lower efficiency.

Energy Efficiency

You want your chiller to deliver strong performance while using less energy. Water cooled screw chillers excel in energy efficiency. Water absorbs heat better than air, so these chillers use less electricity to cool large loads. Advanced models feature eco-friendly refrigerants and PLC controls that optimize operation. Air-cooled chillers work well for small to medium applications but may consume more energy in high-temperature environments. If you run a large industrial process, you benefit from the superior efficiency of water cooled screw chillers.

Installation

You must plan for installation requirements before making a decision. Water cooled screw chillers need indoor space and a reliable water supply. You also install a cooling tower, which adds complexity and time to the project. Air-cooled chillers are stand-alone units. You can install them quickly outdoors, saving valuable indoor space. If you want a faster setup, air-cooled chillers offer a clear advantage.

Maintenance

You should prepare for regular maintenance to keep your chiller running smoothly. Water cooled screw chillers require more attention. You need to treat water to prevent corrosion and clogs. You also clean tubes and monitor water quality. Air-cooled chillers have fewer components, so maintenance is simpler. You mainly check refrigerant levels and clean condenser coils.

• Corrosion can lead to leaks and damage if you do not treat water properly.

• Poor maintenance may result in clogs and reduced efficiency.

Lifespan

You want your chiller to last as long as possible. Water cooled screw chillers often have a longer lifespan. Indoor placement protects them from weather and temperature swings. You extend their life with regular maintenance and water treatment. Air-cooled chillers sit outdoors, so they face rain, dust, and heat. These conditions can shorten their service life. If you prioritize durability, water cooled screw chillers offer better long-term value.

Environmental Impact

You need to think about how your choice affects the environment. Water cooled screw chillers use water, but many modern models run on eco-friendly refrigerants. Advanced controls help reduce energy use and emissions. Air-cooled chillers do not consume water, which makes them suitable for regions with water scarcity. However, they may use more electricity, especially in hot climates, which can increase your carbon footprint.

Water Use

You must evaluate water consumption before selecting a chiller. Water cooled screw chillers require a steady supply of water. Usage varies by city and climate. For example, annual water consumption per ton ranges from 1.1 kGal in Minneapolis to 4.1 kGal in Phoenix.

Air-cooled chillers do not use water, making them ideal for facilities in water-restricted areas.

Noise

You should consider noise levels, especially if your facility is near offices or residential zones. Water cooled screw chillers operate quietly indoors, with noise levels between 55 and 65 decibels. This is similar to a conversation or background music. Air-cooled chillers produce more noise, ranging from 70 to 80 decibels, which you can compare to a vacuum cleaner or a busy street.

Suitability by Industry

Large-Scale Manufacturing

You should choose a water cooled screw chiller for large-scale manufacturing. Industries such as plastics, chemicals, and concrete production rely on these chillers for their broad capacity coverage and reliable load-following performance. Market reports show screw chillers hold a 38.3% share in these sectors, with centrifugal chillers gaining momentum due to efficiency and reduced maintenance needs.

• Screw chillers offer cost-effectiveness and low maintenance.

• You see them most often in plastics, chemicals, and pharmaceuticals.

Medium & Small Facilities

For medium and small facilities, you need to focus on operational efficiency and cost-effectiveness. Chillers with capacities between 50 and 200 tons fit these operations well. You should consider the layout and available space in your facility, as well as the need for precise temperature control.

• You benefit from chillers that maintain precise temperature and offer easy installation.

Water-Restricted Locations

If your facility is in a water-restricted area, you should select an air-cooled chiller. These chillers do not require a water supply or cooling tower, making them ideal for remote sites or regions with limited water resources.

Air-cooled chillers help you avoid water costs and simplify installation.

High Temperature Areas

In high temperature industrial areas, you should rely on water cooled screw chillers. Water has higher thermal conductivity than air, so these chillers deliver greater cooling efficiency and stable performance. You also experience quieter operation because they do not depend on large fans.

Urban vs Remote Sites

You need to consider site conditions when choosing a chiller. In urban environments with limited space, air-cooled chillers fit well on rooftops and offer a compact footprint. For remote sites or projects needing fast deployment, air-cooled chillers provide easy installation and lower initial costs. Water-cooled chillers consistently outperform air-cooled systems in environments demanding high efficiency and stable operation, such as large-scale manufacturing or a data center.

• Choose air-cooled chillers for space-limited urban sites or remote locations.

• Select water-cooled chillers for high-capacity, efficiency-driven projects.
