Why Do Commercial Chillers Form Ice?
Why do commercial refrigerators, such as display chillers or chiller freezers, form ice? How can we remove the ice effectively? Whether it’s a display chiller in a supermarket or a refrigerator at home, their working principles are similar. Ice formation usually occurs due to improper usage, and while it’s normal, it’s important to address this issue correctly to avoid affecting the lifespan of the equipment. Below, Imax Refrigerator Malaysia will explain the causes of ice formation and provide solutions to handle it effectively.
Common Causes of Ice Formation in Commercial Refrigerators
Inappropriate Thermostat Settings
Modern commercial refrigerators typically have adjustable thermostats. The higher the number on the thermostat, the lower the temperature. Incorrect settings can result in excessive cooling, leading to ice buildup.
Uneven Food Storage
If food is stored too close to the inner walls of the refrigerator, it can disrupt airflow and cause frost or ice formation near the internal surfaces.
Faulty Thermostat Sensor
A malfunctioning thermostat sensor may fail to detect temperature changes accurately, leading to overcooling and eventual ice formation.
Frost Turning into Ice
During summer, the external temperature is significantly higher than the inside of the refrigerator. When the refrigerator door is opened, warm air enters and condenses into frost on the cooler surfaces. Over time, this frost can harden into ice.
How to Remove Ice from a Commercial Refrigerator
If ice has already formed in your commercial refrigerator, follow these steps to remove it safely:
Power Off the Refrigerator
Disconnect the power supply and remove all food items from the refrigerator.
Let the Ice Melt Naturally
Allow the ice to melt at room tempertures. This method is safe but may take time.
Use Proper Cleaning Tools
If you want to speed up the process, use specialized refrigerator cleaning tools. Avoid using sharp or metal tools, as they can damage the internal components, such as the cooling pipes.
Tips to Prevent Ice Formation
To reduce the likelihood of ice forming in your display chiller, chiller freezer, or other refrigeration equipment, follow these best practices:
Allow Hot Food to Cool Before Storing
Placing hot or warm food directly into the refrigerator increases humidity levels, leading to ice formation. Wait until the food has cooled before storing it.
Cover Moist Food Items
Foods with high moisture content should be wrapped in plastic wrap or stored in airtight containers. This not only preserves the food’s freshness but also minimizes humidity levels inside the refrigerator.
Apply a Thin Layer of Edible Oil
After cleaning the refrigerator, apply a thin layer of edible oil on the inner walls. This can prevent ice from sticking to the surfaces and make future cleaning easier.
Conclusion
Understanding why commercial refrigerators form ice and knowing how to prevent and address this issue can significantly enhance the performance and lifespan of your equipment. By following the tips above, you can ensure optimal operation of your display chiller, chiller fridge, or other refrigeration units.
