Medium-Temperature Unit Cooler

Incorporating a suite of proprietary engineering innovations — including floating coil technology, positive-row fin arrangement geometry, Italian tube expansion processes, and premium German-brand axial flow fans — the Medium-Temperature Unit Cooler delivers measurably superior heat transfer performance, reduced frost accumulation, extended service life, and lower acoustic emissions compared to conventionally designed air coolers in its class.

Every unit is manufactured using automated welding processes and assembled with stainless steel fasteners and connectors throughout, ensuring consistent product quality and long-term structural integrity in the humid, demanding environments typical of cold storage and food processing installations.

The medium-temperature unit cooler is available in a comprehensive range of models, configurations, cooling capacities, and material options, providing refrigeration system designers, cold storage engineers, and facility operators with a versatile, high-performance cooling solution precisely matched to their specific application requirements.

Core Technological Advantages

Installation and Application Design Guidelines

Coil Selection for Near-Freezing Applications: For medium-temperature applications operating consistently at temperatures between 0°C and +3°C — where frost formation is most active — the positive-row fin arrangement and floating coil design of the Medium-Temperature Unit Cooler provide the best combination of frost resistance and structural durability. Electric defrost is recommended for these near-freezing applications to ensure complete, reliable frost removal and prevent progressive coil icing that could restrict airflow and degrade performance.

Humidity Management: In fresh produce and controlled atmosphere cold storage applications, maintaining appropriate relative humidity levels is as important as temperature control for product quality preservation. Unit cooler selection and sizing should account for the moisture removal characteristics of the coil, and supplementary humidification equipment should be considered where relative humidity targets cannot be maintained by the refrigeration system alone.

Air Distribution Planning: Careful planning of unit cooler placement and air throw direction is essential for achieving uniform temperature distribution throughout the cold room volume. For rooms with high ceiling heights or complex geometries, computational fluid dynamics (CFD) air distribution modeling may be beneficial to verify temperature uniformity and identify potential dead spots before construction.

Drainage System Design: Adequate defrost water collection and drainage provisions are essential for reliable medium-temperature unit cooler operation. Drain pans should be properly sloped to the drain connection, drain lines should be correctly sized for the defrost water flow rate, and drain connections should exit the cold room through properly insulated and, where necessary, electrically heat-traced penetrations to prevent drain line freezing in near-zero temperature applications.
