RKVD Double-Row V-shaped Gas Coolers

High heat dissipation capacity within a compact footprint for large-scale CO2 systems.

The double-row V-shaped solution for continuity, high airflow, and stability even under high thermal loads

Managing heat dissipation within the high-pressure side of large-capacity CO2 refrigeration systems requires installation spaces that are often unavailable: crowded rooftops, incompatible layout widths, disrupted airflow paths, or the physical impossibility of installing multiple units side-by-side as the thermal load expands with plant growth.

The risk is having systems that lose efficiency during the hottest days of the year, forcing the entire plant to operate under conditions much more severe than design parameters, thereby increasing energy consumption, the likelihood of high-pressure alarms, and irregular operating cycles.

The RKVD series is specifically optimized for large-scale, high-capacity plants: a compact, high-efficiency solution featuring a double-row V-bank configuration, engineered to concentrate massive heat transfer surface areas within a minimized footprint, while maintaining a uniform and easily manageable airflow.

Advantages of Double-Row V-shaped Gas Coolers

High heat transfer capacity within a compact footprint: Thanks to the highly compact V-shaped configuration, which concentrates a surface area equivalent to much larger units without requiring an increase in the installation width.
Operational continuity: Driven by the integration of dual independent refrigerant circuits, ensuring more stable head pressure management even under unbalanced load conditions or during partial load operation.
More uniform heat transfer efficiency: Thanks to the V-shape geometry that allows airflow to distribute evenly across the entire fin pack, reducing the need to run fans at maximum rotation speed.
Structural robustness: Guaranteed by inner-grooved K65 copper alloy tubes and a dedicated coil suspension system that limits vibrations and the risk of micro-leaks in high-capacity applications, ensuring superior long-term reliability.
Reduced operating noise: Achieved via high-efficiency axial fans that deliver high volumetric airflow rates with low power consumption, simplifying system integration on sensitive or residential-adjacent rooftops.
Extensive configuration options: With 72 available models, multiple fin spacing choices, and a selection between AC or EC fans, allowing the unit to adapt precisely to specific capacity, space, and acoustic requirements.
