RDVM-PAD liquid coolers with adiabatic PAD system

High-performance adiabatic cooling even during peak loads.

V-shaped system with evaporative panels active only when needed

In many medium-to-high power industrial and HVAC systems, strict water consumption limits and the requirement for continuous cooling impose a difficult technical choice. Engineers must guarantee high performance throughout the year without resorting to expensive chemical water treatments, or oversized systems.

Designed to achieve this balance, the RDVM-PAD adiabatic coolers use an adiabatic panel system that activates only when necessary. This ensures effective and continuous cooling without the need for invasive system interventions. Its compact design, ease of maintenance, and the absence of chemical treatments make this solution ideal for production, logistics, and HVAC environments where stability and simplicity are paramount.

Advantages of PAD system adiabatic liquid coolers

Adiabatic system always available: utilizes an evaporative panel system that requires no chemical treatments or specialized anti-corrosion protection for the exchanger.
Continuous and stable operation, even in hot climates or during extended cycles, with no limits on the number of operating hours in adiabatic mode.
Reduced energy and water consumption, achieved through advanced control logic that manages selective partialization between ventilation and humidification.
Zero contamination of the primary circuit: evaporative water never comes into direct contact with the heat exchanger.
Simplified accessibility and cleaning, featuring a compact structure with quick lateral access and no requirement for anti-algae or anti-limescale treatment.
Easy integration: low height, constant width of 1180 mm and flanged headers facilitate compact installation.
