As a supplier in the supermarket refrigeration industry, I’ve seen a lot of debates about the best type of refrigeration systems for supermarkets. One of the most common discussions is the difference between open – display and closed – door supermarket refrigeration. In this blog, I’m gonna break down these two types of refrigeration, talk about their pros and cons, and help you figure out which one might be the best fit for your supermarket. Supermarket Refrigeration
How They Work
Let’s start with how these two systems operate. Open – display refrigeration units, as the name implies, are open to the supermarket environment without any doors. They rely on a continuous flow of cold air that cascades down the front of the display to keep the products cool. This creates a sort of "air curtain" that acts as a barrier between the cold interior of the unit and the warmer supermarket air.
On the other hand, closed – door refrigeration units are enclosed with doors. The cold air is trapped inside the unit, and when a customer opens the door to access a product, only a small amount of cold air escapes. The unit then quickly cools back down to the set temperature.
Energy Efficiency
Energy efficiency is a huge concern for supermarkets. Running refrigeration systems accounts for a significant portion of a supermarket’s energy costs.
Open – display units tend to be less energy – efficient. Since they’re open, there’s a constant exchange of cold and warm air. The refrigeration system has to work harder and run more often to maintain the right temperature. This means higher energy consumption and, ultimately, higher electricity bills.
Closed – door units are generally more energy – efficient. The doors act as an insulator, reducing the amount of cold air that escapes and the amount of warm air that enters. This means the refrigeration system doesn’t have to work as hard, leading to lower energy consumption. For example, a study by some industry experts found that closed – door refrigeration units can reduce energy consumption by up to 40% compared to open – display units.
Product Visibility and Accessibility
When it comes to product visibility, open – display units have a clear advantage. Customers can easily see all the products on display without having to open any doors. This makes it quicker for them to find what they’re looking for. It also creates an inviting and accessible shopping experience, which can lead to increased impulse purchases.
Closed – door units, however, can make it a bit more difficult for customers to see all the products inside. The glass or plastic doors can sometimes create a glare, and products at the back of the unit may be harder to spot. But, modern closed – door units are designed with better lighting and clear doors to minimize these issues.
In terms of accessibility, open – display units win again. Customers can simply reach in and grab what they want. With closed – door units, customers have to open the door first, which can be a bit of a hassle, especially if their hands are full.
Product Preservation
Product preservation is crucial in a supermarket. You want to keep your products fresh and safe for as long as possible.
Open – display units expose products to the supermarket environment, which means they’re more likely to be affected by changes in temperature and humidity. This can lead to faster spoilage, especially for products like fresh produce and dairy.
Closed – door units provide better protection for products. The enclosed environment helps to maintain a more stable temperature and humidity level, which can extend the shelf life of products. For example, meat products stored in closed – door units may stay fresh for a few days longer compared to those in open – display units.
Cost
The cost of purchasing and installing the refrigeration units is another important factor.
Open – display units are generally less expensive to purchase upfront. They’re simpler in design and don’t require the additional components like doors and door – closing mechanisms. However, as mentioned earlier, their higher energy consumption means higher long – term operating costs.
Closed – door units are more expensive to buy and install. The doors and the technology needed to ensure proper sealing and temperature control add to the cost. But, the lower energy consumption can offset the initial investment over time.
Customer Behavior and Preferences
Customer behavior and preferences also play a role in choosing between open – display and closed – door refrigeration.
Some customers prefer the open – display units because of the easy access and the ability to quickly scan all the products. They like the "grab – and – go" convenience. On the other hand, some customers appreciate the energy – saving aspect of closed – door units and don’t mind opening the doors to get their products.
Supermarkets also need to consider the type of products they’re selling. For products that are more impulse – buy items, like snacks and beverages, open – display units may be more effective. For products that require better preservation, like high – end meats and cheeses, closed – door units may be a better choice.
Which One Should You Choose?
So, which type of refrigeration is right for your supermarket? Well, it depends on a few factors.
If you’re on a tight budget and want to provide easy access to products, open – display units might be a good option. They’re great for creating an inviting shopping environment and promoting impulse purchases. However, if you’re looking to save on energy costs and improve product preservation, closed – door units are worth the investment.
You can also consider a combination of both. Use open – display units for popular, impulse – buy items at strategic locations in the store, and closed – door units for products that need better protection.
