RDS – RDL Flat liquid coolers

Maximum configuration flexibility with an optimised footprint.

The compact solution for cooling with water, glycol and non-freezing fluids

When available space is limited, selecting the right dry cooler for industrial refrigeration becomes a critical challenge. Inaccurate sizing can lead to inefficient heat exchange, increased outlet temperatures, higher energy consumption, or fans operating under extreme stress.

To address these challenges, Refteco developed the RDS and RDL flat liquid coolers, a range engineered to deliver the perfect synergy of compactness, high capacity, and silent operation. Available both in horizontal and vertical configuration, and featuring either a short frame (RDS) or a long frame (RDL) frame, the series offers over 180 customizable models – this ensures a seamless fit for any industrial plant requiring reliable cooling with non-freezing fluids.

Advantages of our flat liquid coolers

Space-saving design short-frame RDS version and optimized component layout allow for easy installation in confined environments.
Ultra-quiet performance sound pressure levels starting from 30 dB(A) at 10 m, achieved through statically and dynamically balanced ErP-compliant fans, aerodynamic shrouds and the RDL’s extended casing.
Rugged durability built to withstand harsh environments with RAL 9002 powder-coated galvanized steel and corrosion-resistant AISI 304 stainless steel hardware.
Operational reliability: the copper tube and aluminum fin heat exchanger is specifically designed to eliminate contact of the tubes with the frame.
Unmatched versatility: flexible horizontal or vertical mounting, fan diameters ranging from 350 to 910 mm and AC/EC motor options.
Engineering precision, with over 180 models and fin spacing from 2,1 to 4,5 mm to adapt to any thermal and dimensional requirement.
