Vertical Air Curtain Merchandisers are a type of merchandising display with a large, vertical air curtain showcasing products on shelves. These merchandising displays are most commonly used in supermarkets and grocery stores, where fresh produce and other perishable items are displayed. An air curtain is a form of climate control that uses a stream of air to control the flow of temperature, humidity, and other factors to keep a space in the desired environment. Most brands offer units made from stainless steel, plastic, or a combination of both materials. Some brands offer units with a custom design, which may be made from a different material altogether. Compared to other types of merchandiser refrigerators, vertical units tend to have a shorter lifespan. They are installed in a way that allows products to be seen from both sides, and the door(s) can be opened and shut manually or with the help of a motor. Depending on their size, these units can store one or many products, such as fresh produce, meat, dairy, frozen items, or non-perishable items. Depending on the model and manufacturer, these units may have various features, including LED lights, sliding or adjustable shelves, climate control and more.
