The Küba HFE® tube / fin system for maximum energy efficiency |
|
|
|
extensive, ground-breaking research and innovative testing methods have lead to the development of a tube / fin system that offers an optimum combination of maximum heat transfer with minimum loss of pressure.
• Optimised k-value for high refrigeration capacity
• Fan requires low energy input thanks to low air resistance
• Long operating periods due to minimal frost
build-up
• Compact units with high capacity |

The Küba CAL® distributor
for optimum refrigerant distribution |
|
|
Küba Air Coolers for direct expansion with multiple injection are equipped with the patented Küba CAL® distributor.
• A consistent performer across the entire application spectrum, the Küba CAL® distributor always works at the optimum capacity
• Complete, consistent refrigerating capacity at all times, regardless of refrigerant and ambient temperature
• Maximum energy efficiency even in partial-load operation, thanks to even refrigerant distribution
• Universal flexibility from +40°C to -55°C |
|
CAL® distributor effect: Even distribution
of frost on fins |

Optimal defrosting for all applications |
|
|
Based on the overall concept of the refrigeration system, any of the established defrosting methods can be used.
For brine and hot gas defrosting, the tube circuitry is optimized for the specific application. For electric defrosting, expanded heater tubes chieve the optimum connection to the fin.
• Energy transfer with almost no loss
• Shorter defrosting periods due to lower defrost timeout temperature in the heat exchanger
• Minimal vapour build-up due to low surface
temperature on the heater tube (< 95 °C) |
|
Ideal Heat Transfer with a High Primary to
Secondary Ratio thanks to expanded
heater tubes |

|
Best material selection and workmanship |
|
|
Küba Air Coolers have lasting corrosion protection and are not overly sensitive to cleaning procedures, thanks to their scratch-resistant surface.
• We use the best materials and high-quality components for each application because high product quality starts in purchasing
• Perfect surface finish, e.g. with a food safe, nonpolluting powder coating that is applied before assembly: corrosion protection even for inaccessible components. |

Hygiene you can see: Smooth hygienic
surfaces and in addition to that a long-
lasting corrosion protection |
