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.


Benefit/Impact

Description

Improved Efficiency

Preventing scale buildup ensures optimal operation, enhancing heat transfer and reducing energy use.

Extended Equipment Life

Scale deposits can cause corrosion; effective control minimizes degradation, prolonging lifespan.

Reduced Maintenance and Downtime

Proper scale control reduces unscheduled maintenance, increasing productivity and reducing costs.


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.

You can rely on the Siemens PLC control panel to monitor water quality and temperature. The system automatically adjusts compressor energy to maintain optimal conditions, which limits scaling. You get timely alarms if water temperature or flow changes, so you can take action before scaling becomes severe. These features work together to provide effective solutions for scaling, keeping your high-performing cooling system running smoothly.

Corrosion Control

Corrosion can damage your cooling equipment and shorten its lifespan. The industrial air cooled screw chiller offers several treatment solutions to control corrosion. The OMC-100ASH uses light water aluminum and blue aluminum foils to protect copper tubes from harsh environments. These materials add a protective layer, extending the life of your condenser and ensuring reliable cooling performance.

You also benefit from the Black Fin Heat Exchanger, which uses a complex resin to shield your system from corrosive elements. If you need extra durability, you can choose a Blygold coating for even stronger protection. The chiller’s robust safety system includes high and low pressure safeguards and compressor overheating protection. These features help you maintain safe operation and reduce the need for frequent treatment.


Many industries trust industrial air cooled screw chillers for corrosion control. Here is a table showing where these chillers are most commonly used:

Biofouling Reduction

Biofouling occurs when bacteria, algae, and other organisms grow inside your cooling system. The industrial air cooled screw chiller helps you reduce biofouling with several treatment solutions. The OMC-100ASH uses a unique oil pressure system that ensures optimal lubrication without an oil pump. This design reduces vibration and noise, making it harder for organisms to settle and grow.


You can use the LCD touch screen to monitor system conditions and receive alerts if biofouling starts to develop. The chiller’s automated fault detection lets you respond quickly with the right treatment. By keeping water temperatures stable and improving air distribution, you limit the conditions that allow biofouling to thrive.

  • Industrial air cooled screw chillers support sustainability goals by using refrigerants with reduced global warming potential. Their efficient design lowers energy consumption and greenhouse gas emissions. You can reuse residual heat for space heating or other industrial processes, which reduces your reliance on additional energy sources and supports a more sustainable operation.
