Commercial chest freezers are crucial in many food establishments, from food joints and cafes to supermarkets and catering services. They provide ample storage for frozen goods, ensuring the meals stay fresh and safe for extended periods. However, these appliances can also be significant energy consumers, leading to high electricity costs.
By implementing innovative power-saving strategies, business owners can reduce their electricity bills while maintaining the efficiency of their chest freezers. This blog will explore practical energy-saving tips for these classic appliances, helping businesses operate sustainably without compromising food safety.
Get ample storage while using minimal floor space, with easy access and organisation of your frozen goods. Take a look at our Upright Freezers.
1. Choose an Energy-Efficient Model
Investing in a power-efficient commercial chest offering can significantly reduce energy consumption. When choosing an appliance, think about the given below factors:
Look for Energy Star Ratings
Energy-efficient chest options have an Energy Star rating, indicating they meet strict electricity-saving guidelines. These models use advanced insulation, high-efficiency compressors, and improved temperature controls to reduce power usage.
Opt for Inverter Technology
These options with inverter compressors adjust their cooling power based on demand. Unlike traditional compressors that turn on and off frequently, inverter compressors maintain a consistent temperature while consuming less power.
Consider the Size and Capacity
Choosing the right size is essential. A freezer that is too large for your needs will waste electricity. In contrast, an overloaded appliance may struggle to maintain optimal cooling. Check your storage requirements and choose an option that balances capacity and efficiency.
2. Maintain Proper Temperature Settings
Setting the correct temperature ensures food stays frozen without unnecessary power consumption.
Recommended Temperature
The ideal temperature for a commercial cooling appliance is between -18°C and -22°C. Lowering the temperature further increases energy usage without significantly improving food preservation.
Use a Digital Thermometer
Many commercial chest freezers have built-in temperature displays, but an external digital thermometer can help verify accuracy. Frequently check the temperature to ensure it stays within the ideal range.
Avoid Frequent Adjustments
Constantly changing the temperature settings forces the equipment to function intensely, resulting in higher electricity usage. Set a stable temperature and check it regularly.
3. Keep the Equipment Full But Not Overcrowded
The way you store items in a chest option impacts its efficiency.
Benefits of a Well-Stocked Freezer
A fully stocked appliance retains chilled air better than an empty one. Frozen items help maintain low temperatures, reducing the workload on the compressor.
Avoid Overloading
Overcrowding blocks airflow, making it difficult for cold air to circulate evenly. This issue forces the offering to work harder, increasing power usage. Organise food items properly, leaving some space for air circulation.
Use Containers and Bins
Storage bins or baskets maximise space while maintaining good airflow. Proper organisation also reduces the time spent searching for items and minimises the time the product door stays open.
4. Minimise Door Openings and Keep the Lid Sealed
Frequent door openings cause warm air to enter, making the chest freezer for sale function harder to preserve the ideal temperature.
Limit Door Openings
Encourage staff to plan before opening the appliance. Knowing what your employees need beforehand reduces the time spent searching for items inside.
Check the Door Seal Regularly
A damaged or loose gasket (door seal) allows cold air to escape, leading to higher energy consumption. Check the seal frequently and change it if it is worn or cracked. Place a piece of paper between the lid and the product to test for leaks. If it slides out quickly, the seal needs replacement.
Ensure Proper Lid Closure
Make sure the item lid closes entirely after each use. Avoid overfilling the product to prevent items from blocking the lid.

5. Place the Freezer in an Optimal Location
Where you position your chest freezer affects its electricity efficiency.
Avoid Heat Sources
Keep the appliance away from ovens, stoves, dishwashers, and direct sunlight: excess heat forces the freezer to work harder, increasing power consumption.
Ensure Proper Ventilation
Commercial large or small chest freezers release heat while operating. Placing them too close to walls or other appliances restricts airflow, leading to overheating and reduced efficiency. Leave 5–10 cm of space around the cooler for proper ventilation.
Maintain a Cool Room Temperature
If possible, place the offering in a cool, well-ventilated area. Air-conditioned rooms help reduce strain on the compressor, improving electricity efficiency.
6. Regularly Defrost and Clean the Freezer
Ice buildup inside the product reduces efficiency by blocking airflow and increasing energy consumption.
Defrost the Freezer When Needed
If your commercial chest freezer nearby has no auto-defrost feature, manually defrost it when ice buildup exceeds 5mm thick. Excessive frost makes the equipment work harder to maintain low temperatures.
Keep the Interior Clean
Frequent cleaning controls dirt and debris from choking air vents. Wipe spills immediately to avoid ice formation and maintain a clean environment.
Clean the Condenser Coils
The condenser coils take out heat from the chilling device. Dust buildup on coils reduces efficiency and increases power consumption. Clean them every 3–6 months using a soft brush or vacuum cleaner.
7. Use Night Covers or Lids for Open Display Chest Freezers
Consider using night covers or sliding lids if you operate a supermarket or retail store with open-display chest options.
Benefits of Night Covers
Reduces electricity loss when the store is closed.
It prevents warm air from entering, helping maintain stable temperatures.
Extends the lifespan of the model by reducing strain on the compressor.
Simple night covers can save 10–20% energy costs over time.
8. Monitor and Reduce Energy Consumption
Keeping track of power usage helps identify inefficiencies and areas for improvement.
Use Power Monitoring Devices
Install smart energy meters to track the equipment's electricity consumption. An unexpected spike in usage may indicate a problem with the model, door seals, or temperature settings.
Schedule Regular Maintenance
Routine servicing by an experienced technician guarantees the product's efficient operation. Maintenance inspections can help locate and resolve issues before they lead to higher energy costs or breakdowns.

Upgrade to LED Lighting
Suppose your appliance has an internal light; switch to LED bulbs. LED lights consume less energy and produce minimal heat, reducing the load on the cooling system.
9. Use Smart Energy-Saving Practices
Easy-to-follow habits can make a significant difference in reducing energy consumption.
Turn Off When Not in Use
If your industrial device is unused for extended periods, consider turning it off to save electricity. Empty and clean it before switching it off.
Use Timers and Smart Plugs
Smart plugs and timers can help manage power usage efficiently. For example, during non-peak hours, the commercial chest freezer can operate at a slightly higher temperature without affecting food quality.

Take Advantage of Off-Peak Hours
Some power providers provide lower rates during off-peak times. To minimise energy costs, schedule equipment maintenance or defrosting during these hours.
