RDVD liquid coolers V-shape

High power dissipation in small spaces.

The compact solution for systems over one megawatt

In high-power refrigeration systems, the choice of liquid cooler affects every aspect of the project: occupied surface area, installation costs, thermal balance and even perceived noise levels. When working beyond a megawatt, every design detail must be precisely calibrated: an oversized machine can block a construction site’s logistic, while an inadequate one compromises the stability of the entire system.

To meet these demands, Refteco developed the RDVD liquid coolers with V-shaped coils. This compact and modular solution is capable of adapting to the densest layouts, ensuring operational continuity even in the event of partial failures, and reducing noise without sacrificing heat exchange. It is a solution that simplifies onsite installation, optimizes the dimensions, and guarantees continuity even in the most critical contexts.

Advantages of liquid coolers with V coils

Maximum power dissipation, featuring a double V-coil and a compact footprint.
Optimized installation, thanks to the fixed width of 2203 mm for all versions, ranging from 4 to 16 fans.
Reduced noise emissions, starting from 30 dB(A) at 10 m, utilizing statically and dynamically balanced, ErP-compliant fans.
Guaranteed operational continuity, features physical separation of ventilation modules and fans protected by thermal contacts.
Low pressure drops: engineered with 12 mm copper pipes and PN16 (EN 1092) flanged aluminium headers.
Enhanced summer performance through the integration of the spray or PAD adiabatic system
