Night Curtains for Display Fridges – Simple and Effective Energy Savings

What are night curtains and why do they matter for your business

If you own a food store, supermarket or HoReCa establishment, you know all too well that display fridges run around the clock. Even when the store is closed, the compressors work non-stop to maintain the optimal temperature of the products. This is where a simple yet highly effective solution comes in: night curtains for display fridges.

These curtains, also known as night blinds or thermal roller blinds, are flexible or rigid panels that cover the opening of display fridges at night or during periods without customers. The result? A significant reduction in electricity consumption, with no compromise whatsoever on refrigeration quality.

How much can you save with night curtains

The figures speak for themselves. Studies conducted in the commercial refrigeration industry show that night curtains can reduce the energy consumption of open display fridges by up to 35–40% during the hours when the store is closed. For a store with multiple rows of open display fridges, this can mean hundreds or even thousands of lei saved every month on the electricity bill.

The mechanism is straightforward: when a display fridge is open and uncovered, cold air constantly escapes into the sales area, forcing the compressor to work harder to compensate for the temperature losses. A fitted curtain dramatically reduces these thermal losses, especially at night, when outdoor temperatures can drop considerably.

Types of night curtains – which option suits you best

Not all curtains are the same. Depending on the type of display fridge and the specific needs of your business, you can choose from several options:

• Transparent or semi-transparent film curtains – easy to handle, inexpensive and effective for display fridges where products need to remain visible.
• Thermal insulating fabric roller blinds – provide better insulation and are suitable for high-capacity display fridges.
• Rigid fold-down panels – a robust solution, ideal for display fridges with high customer flow and wide openings.
• Automatic sensor-operated systems – open and close on a schedule or upon detecting customer presence, with no manual intervention required.

At Modaco, commercial refrigeration equipment is designed to be compatible with night curtain systems, making it easy to integrate these energy-saving solutions right from the point of purchase.

Benefits beyond energy savings

Reducing the energy bill is the primary advantage, but night curtains deliver other tangible benefits as well:

• More stable temperature maintenance – reduced fluctuations protect food products and extend their shelf life.
• Less wear on the compressor – when refrigeration losses are minimal, the compressor starts less frequently, resulting in a longer service life for the equipment.
• Reduced condensation – curtains limit the entry of warm, humid air into the display fridge, preventing the formation of ice and condensation on products or shelves.
• Compliance with environmental regulations – using energy-efficiency solutions helps you meet the increasingly stringent European standards for energy consumption in retail.

Practical tips for correct implementation

Fitting night curtains is straightforward, but a few details make the difference between an effective solution and one that fails to deliver the expected results:

• Choose curtains sized precisely to the display fridge opening – gaps left uncovered negate a large portion of the benefits.
• Use certified curtains that are compatible with the type of display fridge – always check the manufacturer's recommendations.
• Train staff to draw the curtains every evening when the store closes – a simple habit can generate consistent savings.
• Periodically check the condition of the curtains – damaged materials or tears reduce thermal efficiency.
• Combine night curtains with other energy-efficiency measures, such as LED lighting for display fridges or programmable thermostats.
