RGDC dual-flow commercial air coolers

Maximum efficiency in compact spaces for cold and processing rooms.

The dual flow solution designed for stable microclimates in low-ceilings environments

In processing rooms and commercial cold rooms with low ceilings, guideways, ducts or sloping structures, available space is often minimal. In these settings, the refrigeration system must distribute air evenly without creating direct drafts on workstations and without compromising microclimate stability, particularly when using water, glycol, or other non-freezing fluids.

If the air flow is concentrated in a single point, the air tends to stratify: some areas become colder, while others remain poorly ventilated. This can lead to irregular cycles and energy consumption that does not reflect actual thermal needs, with effects on both product quality and comfort of the operators.

RGDC dual-flow air coolers are designed specifically for these situations: thanks to their low-profile design, symmetrical air flow on both sides, and heat exchangers optimized for non-freezing fluids, they maintain uniform and comfortable conditions even in the most constrained environments. The result is a more balanced, quiet and easy-to-manage cooling solution for daily use.

Processing rooms and areas with low ceilings

Advantages of commercial dual-flow air coolers

Uniform cooling even with low ceilings, thanks to the symmetrical air discharge on two fronts that distributes the air flow along the entire room, avoiding overly cold areas under the unit and improving microclimate quality.
High efficiency with water, glycol and non-freezing fluids, guaranteed by coils with tubes and fins of appropriate thickness, designed to maintain good heat exchange even with low flow rates typical of hydronic systems.
Reduced dehumidification and frost formation, thanks to the coil geometry designed for continuous cycles and commercial operating conditions, where humidity stability is fundamental for product preservation.
Durability over time, thanks to the painted aluminum casing, AISI 304 stainless steel hardware and a design intended for humid environments or those subject to frequent washing.
Quick maintenance even without lateral space, thanks to hinged drip tray and frontal arrangement of components, which allows for both cleaning and inspections without having to disassemble the unit or completely clear the area below.
Installation flexibility, with 48 models and a wide range of options that allow for precise sizing in cold rooms from 20 to 200 m³ or in processing rooms with height limits.
