Kistefrisorer

Kistefrisorer is a term used in Nordic technical literature to describe box-shaped refrigeration units designed for short-term preservation of perishable goods. The name mixes kiste meaning "box" and fryser meaning "freezer" in Scandinavian languages, reflecting a crate-style design. In English, the exact term is uncommon; similar devices are usually called portable coolers or insulated crates.

Design and variants: Kistefrisorer range from portable to stationary units with insulated panels, a lid, and an interior liner (often stainless steel). Capacities commonly span 50 to several hundred liters. Typical operating temperatures are around -18 C, with some models adjustable from about -25 to 0 C. Cooling is usually compressor-based, though smaller units may use thermoelectric modules; energy use depends on size and insulation.

Applications: They are used for short-term storage and transport of foods, pharmaceuticals, or laboratory samples, especially in markets, catering, field operations, and regional deliveries where conventional refrigerators are impractical. Some versions include battery or solar charging for off-grid use.

Regulation and history: Kistefrisorer equipment must meet general refrigeration safety standards, food-contact regulations, and electrical codes in respective countries. The concept emerged in the mid-20th century as a practical portable cold-storage solution; modern variants remain common in Nordic markets, though the exact term may be replaced by generic descriptors in many contexts.
