Tragkühlgeräte

Tragkühlgeräte, often referred to as portable refrigerators or cooler boxes, are insulated containers designed to keep food and beverages cold for extended periods. They are typically made of plastic or metal and feature a double-walled construction filled with insulating material, such as polyurethane foam. This insulation significantly slows down the rate at which heat enters the container, thus maintaining a lower internal temperature.

These devices are powered by various methods. The most basic are passive coolers, which rely solely on the insulation and the use of ice packs or dry ice to maintain cold temperatures. Active coolers, on the other hand, use an electric power source. This can be a 12V DC connection, commonly found in vehicles, or a 110/230V AC connection for use at home or with a generator. Some advanced models also incorporate thermoelectric cooling (Peltier effect) or compressor-based refrigeration systems, offering more precise temperature control and sometimes even heating capabilities.

Tragkühlgeräte are widely used for a variety of purposes, including picnics, camping trips, outdoor events, and long car journeys. They are also employed in professional settings, such as for transporting temperature-sensitive medical supplies or catering food. The size and capacity of tragkühlgeräte vary greatly, from small personal coolers to large units capable of holding multiple days' worth of provisions. Their portability and ability to preserve perishables make them a convenient solution for keeping items cool on the go.
