Here are five simple tips to help keep costs down (and do your bit for the planet!):
1. Position refrigeration units smartly
Where you place your fridges and freezers can make a huge difference.
- Match the environment: Check the climate class of your units. Units built for warmer environments (class 4 or 5) work better in back rooms or warmer zones, while others are better suited to cooler shop floor areas.
- Avoid heat: Keep units away from windows, sunlight or heat sources so the compressor doesn’t overwork.
- Allow airflow: Leave at least 10cm space around your refrigerators for ventilation to prevent overheating and higher energy use.
2. Maintain proper airflow inside and out
Good airflow, both around and inside your units, keeps them running efficiently.
- External airflow: Ensure there’s space around the unit so it doesn’t work harder than necessary.
- Internal airflow: Don’t overcrowd shelves. Evenly spread stock so cold air circulates properly.
3. Avoid overstocking
Overfilling your refrigerators may seem efficient for storage but can have the opposite effect on energy use.
- Uneven cooling: When units are packed tightly, some products won’t be cooled properly, while others may freeze. This is not only inefficient but could also impact food safety.
- Higher energy usage: Overstocking causes the refrigeration unit to work harder to maintain the right temperature, driving up bills and reducing the lifespan of your equipment.
4. Set the right temperatures
Correct temperatures are essential for both energy efficiency and product safety.
- Stay in range: Refrigerators should be set at 4°C to 5°C, while freezers should stay at −18°C. Keep an eye on these settings to avoid energy waste or product loss.
- Tailor for specific products: Some items, such as ice cream or fresh fish, need specific temperature settings. Adjusting for these variations will help prevent overcooling.
5. Regular cleaning and maintenance
Simple upkeep can go a long way in improving efficiency, whilst also ensuring optimal food hygiene standards!
- Clean condensers and vents: Dusty coils or vents will force your refrigeration unit to work harder. Cleaning these every 1–2 weeks helps maintain efficiency.
- Check seals and settings: Worn or damaged seals can allow cold air to escape. Also, ensure temperature settings are correct – set too low, and you’re wasting energy; too high, and you risk product spoilage.
- Schedule servicing: Regular professional maintenance keeps your units in good shape and prevents costly breakdowns in the future.
