RDVM-AD Liquid coolers with adiabatic spray system

The efficient alternative to oversizing for variable load systems.

Integrated dry-adiabatic system for maximum performance

When temperatures soar or the thermal load of a refrigeration system exceeds design specifications, many standard coolers fail: energy consumption spikes, cooling capacity drops, and system alarms are triggered. Oversizing an entire plant just to manage a few hours of peak operational emergency per year is often an uneconomical choice; however, relying on undersized systems can compromise the entire operation.

The RDVM-AD series was engineered specifically for these contexts: these V-shaped single-coil dry coolers operate in dry mode for the majority of the year, activating the adiabatic spray system only during critical ambient conditions. The result is a solution that combines high performance with operational continuity, without wasted energy or unnecessary water consumption. All this in 166 cm high and a constant width of 118 cm.

Advantages of adiabatic liquid coolers

Maximum peak performance the adiabatic spray system activates only when needed, utilizing softened water and management up to 1000 hours per year.
Reduced annual energy consumption, operating in the dry mode most of the time and activating the adiabatic function only upon specific request.
Compact footprint: feature a space-saving structure with a height of 166 cm and a fixed width of 1180 mm, ideal for restricted installations sites.
Noise emissions as low as from 32 dB(A) at 10 m, thanks to statically and dynamically balanced low-speed fans (ErP compliant).
Operational continuity: separate ventilation modules with individual thermal protection ensure the system remains functional even during a partial failure.
Improved hydraulic efficiency: the copper-aluminum heat exchanger features Ø12 mm pipes and flanged headers to significantly reduce pressure drops.
