RGBFT shock freezer air coolers

Targeted power for rapid chilling cycles on trolleys.

The solution designed for intensive freezing in tunnels and compact cold rooms

When meat, fish or pre-cooked dishes are loaded onto multi-tier trolleys in rapid chilling chambers and freezing tunnels, the air cooler must ensure high static pressure and stable airflow across all levels. In these applications, the ability to maintain constant static pressure and heat exchange is essential to meet production cycle times required.

If the airflow does not reach every shelf with sufficient intensity or the coil can not quickly handle the initial thermal load, cooling uniformity is lost: chilling times lengthen, frost forms more rapidly and energy consumption increases. Maintenance activities also become more demanding, especially when space is limited and operations must be performed at low temperatures.

RGBFT shock freezer air coolers are optimized for these conditions: high-static pressure fans, heat exchangers with Ø16 mm smooth tubes designed for non-freezing fluids and a robust structure with easy access ensure uniform cooling, faster cycles and operational continuity even under intensive loads.

Advantages of shock freezer air coolers

Uniform cooling on all trolley levels, thanks to high-static pressure Ø630 mm fans designed to overcome high aerodynamic resistances and maintain constant airflow even in multitier configurations.
Faster and more stable cycles, achieved with Ø16 mm smooth tubes heat exchangers and high spacing fins, guaranteeing continuous heat transfer even during initial thermal load peaks.
Operational continuity in harsh conditions, supported by a tube suspension system that avoids contact with the frame, reducing the possibility of vibrations and micro-leaks while preserving coil life.
Energy efficiency under load, thanks to high-efficiency AC/EC fans with thermally protected external rotor motors, designed for stable operation and controlled power consumption.
Quick maintenance in confined spaces, made possible by a robust structure with easy access, removable panels and a drip tray with a welded stainless steel drain outlet, facilitating inspection and cleaning even in compact tunnels.
Easy installation in existing lines, featuring adjustable feet, with optimized dimensions and the ability of configuring materials, ventilation and accessories according to the specific plant needs.
