Banana ripening air evaporators REDB

Precise microclimate control for multi-level ripening rooms.

The dedicated solution for uniform and consistent banana ripening

Maintaining the microclimate is the critical control parameter in banana ripening: temperature, humidity and air movement must work together to ensure a uniform process, regardless of the number of pallets or their arrangement.

When the ventilation fails to distribute air evenly, or when temperatures fluctuate between different levels of the cold room, ripening becomes inconsistent, and the final product quality suffers.

To provide precise and reliable control under these specific conditions, Refteco developed the REDB air evaporators, a range designed to ensure uniformity, reliability and total microclimate control in multi-level cold rooms with one to three pallet tiers. High-pressure fans, efficient heat exchangers, and optional reversible airflow ensure a stable and consistent ripening process, improving yields and reducing waste.

Application areas

Food & Beverage
Banana ripening rooms with airbags or curtains
Distribution centers and fruit and vegetable platforms

Advantages of banana ripening air evaporators REDB

Uniform air distribution throughout the cold room, thanks to the high-pressure axial fans (Ø500–560 mm) with optional reversible airflow. This ensures a consistent microclimate across different pallet levels and within the pallets themselves, preventing uneven ripening.
High heat exchange, made possible by the heat exchanger with Ø16 mm internally grooved copper tubes and thick aluminium fins, designed for maximum efficiency, lower pressure drops and longer service life even during continuous cycles.
Long-term reliability, guaranteed by a tube suspension system that eliminates contact with the frame, reducing vibrations and thermal expansion to minimize the risk of micro-leaks and protect the coil.
Integrated lighting and stable thermal management, featuring integrated LED lights and circular electric heaters for air heating, which help maintain constant conditions throughout every ripening stages.
Robustness and simplified maintenance, ensured by a RAL 9002 powder-coated galvanized steel casing, AISI 304 stainless steel screws and hinged fan panels that allow quick and safe internal access.
Adaptability to various room configurations, with 15 models designed for cold rooms with 1, 2 or 3 pallet levels, ensuring precise sizing for every facility.
