RGDI Industrial dual-flow air coolers

Distributed efficiency for large cold rooms and processing rooms.

The solution for complex environments with space constraints and variable loads

Guideways, bulky machinery, elevated technical walkways and limited usable heights: in processing rooms and medium-to-large industrial cold rooms the space available for installing units is often restricted. Maintaining a uniform distribution of cold air becomes difficult, and the microclimate tends to become unbalanced: some areas get too cold, others remain poorly ventilated, with the possibility of direct drafts on the production lines. Incorrect air distribution and less efficient cycle operation ultimately increase energy consumption, maintenance and management time.

RGDI industrial double-flow air coolers are specifically designed for these scenarios. Their low profile facilitates installation even in environments with a high concentration of suspended structures, while the symmetrical air discharge on both sides ensures a more balanced distribution of cooling. The heat exchanger, optimized for water, glycol, and non-freezing fluids ensures consistent performance even at low flow rates. The robust structure and appropriately sized fans complete a solution designed to guarantee long-term operational continuity.

Advantages of industrial dual-flow air coolers

Balanced air distribution, thanks to the symmetrical discharge on two fronts, which reduces thermal stratification and direct drafts on workstations, improving comfort and microclimate uniformity.
Efficient heat exchange even at low flow rates, via coils with Ø16 mm smooth pipes and high-thickness fins, ideal for hydronic systems and environments with intensive cycles.
Reduced dehumidification, thanks to the heat exchanger geometry that maintains stability even during continuous operation and variable humidity levels.
Robust structure, with painted galvanized steel casing, welded stainless steel drain outlet and AISI 304 screws, designed to handle frequent washing and demanding working conditions.
Easy maintenance access, with a hinged drip tray that allows for quick frontal interventions without requiring lateral space or unit disassembly.
Maximum design adaptability, with 135 models, 4–10 mm fin spacing, Ø500–630 mm AC/EC fans, and a wide range of options to customize the unit for the specific plant.

Unit coolers for logistic center

Anzola dell’Emilia

For this project relating to the restoration of a big logistic center for the large-scale distribution, we have supplied CO2 evaporators that were installed in low temperature cold rooms for storage of frozen products.
