Radiator RPSD – RPLD

Series of radiators designed for cooling of engines or turbines in cogeneration plants.

RPSD-RPLD radiators can cool hot liquids with temperatures up to 140°C.

This range of liquid coolers is available for horizontal or vertical installation and is equipped with a high performance heat transfer and high-efficiency fans.

RPSD dry coolers with short frame for more compactness or higher capacity for the same size.

RPLD dry coolers with long frame for higher efficiency and lower noise.

Application area

Power plants

Process cooling

Technical features

Over 286 models.

Series RPSD from 4 to 14 fans.

Series RPLD from 4 to 12 fans.

Capacity

From 108 to 570 kW

Fan-motors

Diameter 800 – 910 mm with aluminum or PP plastic blades and corrosion-resistant powder-coated grids. External rotor fans with thermal contacts for effective protection. Fan conveyors with optimized fan profile ensure maximum fan efficiency, lower noise and avoid air recirculation.

Each fan module is separated from the others by partition plates to avoid the phenomenon of air recirculation in case a fan is stopped.

Fin spacing

2,1 – 2,3 – 2,5 – 3,2 – 4,0 mm

Casing

Casing in corrosion-resistant powder-coated galvanized steel. Frame designed to ensure high solidity and uniform air distribution through the heat exchanger. AISI 304 stainless steel screws.

Heat exchanger

The heat exchanger is equipped with a tube suspension system that avoids contact between the tubes and the frame, ensuring complete protection of the battery against vibrations and thermal expansion.

Heat exchanger equipped with 12 mm diameter tubes allows to reduce the pressure drops of the fluid to be cooled and allows to keep the inlet and outlet connections on the same side, reducing installation costs.

Noise

From 30 dB(A) at 10 m distance.

Options

Vertical or horizontal installation, stainless steel tubes, stainless steel casing, coil coating, copper fins, EC fans, ATEX fans, fan speed controller, vibration dampers, fans wiring, safety switches, hail protection net, self-draining heat exchanger.
