Has your cold storage electricity bill inexplicably increased and the cooling rate slowed down? It is likely because the fins of the air cooler are dirty. Regular cleaning is the most cost-effective way to maintain refrigeration efficiency and reduce energy consumption.

Why is it necessary to clean the fins? The cost of not cleaning

When the fins are clogged with dirt:

Increased energy consumption: The heat transfer efficiency decreases, and the compressor needs to work longer to reach the set temperature, which may increase power consumption by 15% -30%.
Decreased cooling capacity: The air output decreases, making it difficult to lower the temperature inside the warehouse, which affects the quality of the goods.
Equipment wear and tear: Prolonged overloading of the compressor can easily lead to malfunctions.
Hygiene risk: In food cold storage, dirt may breed bacteria and contaminate goods.

Suggested cleaning frequency:

Food processing warehouse: Check cleanliness every 3 months
Ordinary refrigerated storage: Check cleanliness every 6 months
Dry and clean environment: Deep cleaning at least once a year

Three step cleaning method (safety first!)

Step 1: Preparation (Power off!)

Turn off the power and lock it
Wear gloves, goggles, and a mask
Preparation: Soft bristle brush, neutral cleaning agent, spray can, warm water

Step 2: Clean according to the type of dirt

Excessive dust: vacuum cleaner → brush gently in the direction of the fins → blow clean with low-pressure air
Oil stains: spray cleaning agent → let stand for 5 minutes → brush lightly → rinse with warm water
Ice cream: Do not hit! First defrost and then clean

Step 3: Conclusion

Wipe dry and thoroughly air dry
Check if the fins are flat
Ensure smooth drainage

Prevention is better than cure: 4 tips to reduce fin contamination

Source control: Install air curtains in the procurement area to reduce the entry of external dust
Regularly replace/clean the primary filter: this is the "first line of defense" to protect the fins
Keep the warehouse clean: Regularly clean to reduce dust
Check the seal: Ensure that the sealing strip of the warehouse door is intact to prevent humid air from entering and aggravating frost
A thorough cleaning can restore the efficiency of the air cooler to its original state and significantly reduce operating costs.
