RDVM liquid coolers V-shape

High performance even with reduced widths.

Industrial cooling without compromising on space

In many systems, the primary challenge is not power, but limited lateral space. Narrow hallways, restricted technical access or engine rooms with closely positioned walls impose tight conditions in the choice of coolers. A unit that is too wide can complicate logistics, hinder airflow or make maintenance points inaccessible. Furthermore, if fan speed is reduced to lower noise levels, there is a risk that the cooler must be oversized, effectively making it unusable in confined layouts.

To address these scenarios, Refteco developed the RDVM liquid coolers with V-shaped coils, featuring a fixed width of just 118 cm. This series offers high thermal performance even at low speeds, low noise levels, and a reduced installation footprint. The modular configuration ensures operational continuity even in the event of partial failures.

Advantages of liquid coolers with V batteries

Simplified side installation, thanks to a constant width of only 1180 mm for all configurations from 1 to 7 fans.
Greater efficiency with the same footprint, featuring V-coils and heat exchangers optimized for low pressure drops.
Low noise emissions, starting from 30 dB(A) at 10 m, thanks to balanced fans and low-speed regulation.
Operational continuity even during partial shutdowns ventilation modules are physically separated by partitions that avoid internal recirculation.
High structural resistance: built with a RAL 9002 powder-coated galvanized frame and AISI 304 stainless steel hardware suitable for harsh environments.
Performance boost for critical summer conditions: integration of the Spray or PAD adiabatic system is available to maximize efficiency.
