How to Prevent Corrosion


Maintain proper cleaning practices. Regular and thorough cleaning is essential to preventing corrosion in your commercial refrigeration. Develop a cleaning schedule and follow manufacturer guidelines for cleaning agents and methods. Remove any spills, debris, or condensation as they occur, don’t let messes and spills sit! Pay special attention to areas prone to accumulation of moisture, like drains and drip pans. Clean and sanitize gaskets, shelves, and interior surfaces regularly to prevent the growth of mold and bacteria which can contribute to corrosion. Proper cleaning practices not only promote hygiene but also prevent the buildup of corrosive substances and prolong the lifespan of your refrigeration equipment.


Control the humidity levels. Excess humidity can accelerate corrosion in commercial refrigeration systems–corrosion loves water! Moisture in the air can condense on refrigeration components, which can lead to quick rust and corrosion. To control humidity, ensure proper insulation of your refrigeration unit and try to minimize air leakage. Install a dehumidification system or use desiccants to remove excess moisture from the air. Consider using moisture-absorbing materials, such as silica gel packs or even baking soda. Monitoring and controlling humidity levels within the recommended range for your unit can help reduce the risk of corrosion and maintain optimal conditions for your refrigeration equipment.


Ensure good ventilation. Poor ventilation can trap moisture and corrosive gases inside your commercial refrigeration unit without you even knowing. Make sure there’s proper airflow around the equipment by maintaining clearances as specified by the manufacturer–aka, make sure there’s enough space around the unit! Regularly inspect and clean ventilation grills, condenser coils, and evaporator fins to prevent dust and debris buildup that can block up proper airflow. Additionally, consider installing exhaust fans or ventilation systems to remove excess heat and humidity from the surrounding environment, especially if in a kitchen. Proper ventilation not only helps in preventing corrosion but also enhances the efficiency and performance of your refrigeration equipment.


Apply protective coatings and finishes. Protective coatings and finishes can provide an extra layer of defense against corrosion. Some refrigeration equipment comes with factory-applied coatings, but if not, consider applying appropriate protective coatings to vulnerable surfaces–it makes a difference. Epoxy or enamel-based paints can protect against moisture and corrosive substances. Stainless steel surfaces can benefit from passivation treatments to enhance corrosion resistance. Regularly inspect and touch up any damaged or worn coatings to ensure continuous protection. Call professionals or manufacturers can help determine the most suitable protective coatings and finishes for your specific refrigeration equipment.


Perform regular maintenance and inspections. Regular maintenance and inspections are critical to identify and address potential corrosion risks in your commercial refrigeration system. Schedule routine maintenance visits from qualified technicians who can clean and inspect key components, such as coils, fan motors, and electrical connections. They can identify early signs of corrosion, replace worn-out parts, and perform necessary repairs. Regular maintenance also includes lubricating moving parts and ensuring proper refrigerant levels. Implementing a comprehensive maintenance plan helps in detecting and prevent corrosion issues before they escalate, thereby maximizing the lifespan and efficiency of your refrigeration equipment.
