Optimize Energy Efficiency in Commercial Freezers

In the world of commercial refrigeration, energy efficiency is no longer just an advantage—it’s a necessity. At Crystal, we understand that proper energy management in professional freezers can lead to significant cost savings and contribute to a more sustainable way of operating.

How can you reduce energy consumption while maintaining high performance?

1. Choose energy-efficient models

The first and most important step is selecting modern, energy-efficient freezers. Crystal’s products are designed to maximize energy savings, featuring:

• State-of-the-art compressors
• Eco-friendly refrigerants
• High-performance insulation
• Advanced Energy Management Design (EMD) that reduces energy consumption while ensuring high performance
• Smart temperature control systems

Investing in an efficient model can reduce electricity consumption by up to 30–40% compared to older technologies.

2. Maintain your freezer regularly

Regular maintenance helps equipment operate at peak performance.

• Defrosting is the first step to proper cleaning; it should be done when the ice thickness inside the unit reaches about 10 mm.
• Clean condensers and ventilation grilles frequently.
• Check door seals for proper sealing.

A well-maintained machine consumes significantly less energy.

3. Set the right temperature

Commercial refrigerators and freezers are designed to operate efficiently under specific climate conditions. Each device’s climate class defines the temperature and humidity range for optimal operation.

Overly low temperatures increase energy consumption unnecessarily. Set your freezer to levels that meet the preservation needs of your products without excess—e.g., -18°C is sufficient for most types of frozen foods.

4. Place the freezer in the ideal spot

Proper placement helps save energy:

• Away from heat sources (like ovens or direct sunlight)
• With sufficient space around it for proper air circulation
• In a well-ventilated area
• Avoiding compressor overload reduces energy use

5. Apply smart usage practices

• Do not leave the door open for long periods
• Fill the freezer appropriately (neither too full nor too empty)
• Group similar products to minimize search time

Good usage minimizes wear on the mechanism and thus reduces energy consumption.

The benefits of energy efficiency and sustainability trends

The shift toward energy-efficient commercial freezers isn’t just about lowering operational costs—it’s directly linked to the commitment to a more sustainable business model.

Advantages:

• Reduced operating costs
• Longer equipment lifespan: Efficient appliances work less strenuously and last longer
• Environmental responsibility: Contributing to CO₂ emission reductions and preserving natural resources

Sustainability Trends:

• Use of natural refrigerants that are more environmentally friendly
• Smart energy management systems with remote control and scheduling capabilities
• Appliances made with recyclable materials and a reduced carbon footprint

Since the end of 2008, we have been manufacturing refrigerators and freezers using hydrocarbons as refrigerants. Their use has been proven to significantly reduce carbon dioxide emissions and environmental impact, while also cutting electricity consumption by up to 30%.

At Crystal, we continuously invest in innovation, creating products that incorporate cutting-edge technology and promote sustainability—with full respect for the environment.
