Push lids and freezer doors from SCHOTT keep frozen food fresher and help reduce costs by saving energy in commercial freezers.

Whole turkeys, fresh meats or frozen pizza – none of these things would be available in local supermarkets without modern refrigeration. To keep food on display at optimal temperatures, food retailers often use so-called freezer islands, large horizontal cases that offer easy access for the customer. In the past, open horizontal refrigeration solutions have been commonplace around the world. This has always made the task of maintaining the mandatory uninterrupted cold chain more challenging – especially in warmer countries such as Brazil. As energy costs soar and hygiene and food quality become more and more important, many food retailers are now turning toward closed freezer islands or looking to retrofit their existing freezers with glass covers. For this, SCHOTT developed high-quality glass doors and push lids and is also partnering with a Brazilian refrigerator manufacturer to further develop customized solutions for the South American continent.
An easy way to make refrigeration more efficient is by retrofitting open refrigeration systems with doors or lids. Another way is by manufacturing the cabinets to offer permanent glass coverage from the start. ”Permanent glass coverage has an energy savings potential of up to 50 percent compared to open refrigeration islands,” says Chueire. SCHOTT Flat Glass was the first company in Brazil to produce highly reliable glass lids and doors to accommodate both approaches. Because the cold air is kept inside the freezer, ice formation inside it is also reduced, thus decreasing the need for defrosting from typically twice in 24 hours to twice a week. Less defrosting means constant, low temperatures and thus lower energy consumption. But besides energy savings, the installation of a covering also offers advantages in relation to food quality because the glass lids protect frozen food from harmful infrared rays.
Furthermore, less defrosting and less heat stress on the food also reduces the formation of frost on – and dehydration of – frozen goods. Lastly, the glass covers also improve overall hygiene, as dirt and grime are kept away from the food.
