KühlDruckcontainer

KühlDruckcontainer is a specialized type of insulated and pressurized cargo container designed for the efficient transport of temperature‑sensitive materials. The system combines a refrigeration unit with a sealed pressure envelope, allowing goods to be stored at low temperatures while maintaining a controlled atmosphere. The name derives from the German words “kühl” (cool) and “druck” (pressure), reflecting the dual emphasis on temperature and pressure regulation.

The concept originated in the late 1970s within the European chemical logistics industry. Early prototypes were used to transport volatile compounds that required both sub‑ambient temperatures and pressure to prevent vaporization or phase change. In the 1990s the technology was adapted for the food sector, enabling long‑haul shipments of dairy products, fresh vegetables, and seafood without compromising shelf life. Today, KühlDruckcontainer are employed in pharmaceuticals, biotechnology, and high‑value technology manufacturing where both temperature stability and atmospheric control are critical.

Construction typically involves a steel hull with multilayer insulation, an integrated refrigeration unit powered by the transport vehicle, and a pressure‑tight door system. Sensors monitor temperature, pressure, and humidity, allowing real‑time adjustments. The containers are rated for pressures up to 2 bar above atmospheric and temperatures down to –30 °C, depending on the model.

Benefits include reduced spoilage rates, lower energy consumption compared to unsealed refrigerated units, and the ability to transport hazardous or corrosive substances safely. Challenges involve higher initial capital costs, the need for specialized training, and complex regulatory approval for certain chemical cargoes.

The KühlDruckcontainer represents a convergence of refrigeration and pressure vessel technology, providing a versatile solution for modern logistics that demand stringent environmental controls.
