Drop-in frost tops are specialized refrigerated countertop units designed to keep pre-chilled food items ready for service in high-traffic buffet lines, salad bars, or self-serve stations. These units are built into the work surface or serving line so that pans of ingredients or snacks sit flush with the counter for fast access while the refrigeration system beneath the top maintains a chilled surface, often at or slightly below freezing. Features typically include a stainless steel top surface with a cold plate or recessed well, integrated drain system, insulated body, and a digital temperature controller that ensures safe holding between -1 °C and +5 °C depending on the load. They use efficient, low-temperature refrigerants to keep items fresh and prevent moisture build-up, and many models include LED lighting, optional overhead gantries, and GN-compatible pan layouts for ease of service. Because they are designed to be embedded in counters, drop-in frost tops save floor space, present ingredients attractively and reduce steps between prep and service zones. For any operation that requires visually appealing, fast-access chilled storage right at the point of service, these units offer a smart combination of performance, presentation and workflow efficiency.
