Reach-in refrigerators are an essential part of every commercial kitchen and store perishable food items. They are usually tall and narrow and have doors that open from the front. There are different types of reach-in refrigerators, but most of them share some common features and functions. Reach-in refrigerators are usually small, so they can only hold a limited quantity of inventory. Reach-in refrigerators are made from stainless steel, aluminum, and glass-reinforced plastic (GRP). They also come with various insulation options, such as foam, bubble wrap, or a combination. Foam insulation is usually better for maintaining temperature accuracy, while bubble wrap is usually better for insulation against noise. Some models have adjustable shelving or multiple doors to accommodate different food sizes and shapes. Many reach-in refrigerators have a door alarm to let you know when it is open. Many units are also designed to keep the door closed when it is not in use. This helps keep heat and cold in the unit where it belongs. You may also want to choose a unit that has a specific layout. Some have a top-loading design, while others have a side-loading design.
