Self Contained Refrigeration Unit K-680
Self Contained Refrigeration Unit is often called a stand-alone refrigeration unit or an integrated refrigeration unit, sometimes simply referred to as an integrated unit.
It describes a structural form and installation method of a refrigeration unit. Simply put, it integrates all core components into a single unit, mounted on the refrigerated container.
The biggest feature of this structure is its high degree of integration:
Integrated Components
The core components of the entire refrigeration system—including the compressor, condenser, evaporator, control panel, and piping system—are integrated into a robust frame, forming a compact whole.
Easy Installation
It is typically designed for direct installation on the front wall (or top) of a refrigerated container. Installation simply involves securing this “big box” to the pre-drilled opening in the container and connecting the power and control lines. It’s like installing a “large air conditioner” in a shipping container.
Independent Refrigeration Cycle
The entire unit is a complete refrigeration system. The condenser dissipates heat externally, while the evaporator absorbs heat internally (within the container). Cool air is then blown into the container through a fan at the opening.
