Gas cooler flat RKSD – RKLD

New line of gas coolers for use in industrial refrigeration systems with CO2 refrigerant fluid.

With a wide range of models with different noise levels and sizes, these gas coolers can meet any plant requirements. This range of gas coolers is available for horizontal or vertical installation.

The heat exchanger is made with special thicker tubes that ensure a design pressure of 120 bar and with fins with innovative configuration that ensure high heat exchange even at low fan speeds.

RKSD gas cooler with short frame for more compactness or higher capacity for the same size.

RKLD gas cooler with long frame for higher efficiency and lower noise.

Application area

Food & Beverage
Logistic centers

Technical features

Over 336 models.

From 4 to 14 fans.

Capacity

From 95 to 860 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.

The RKSD and RKLD series of gas coolers are equipped with stainless steel manifolds that ensure high mechanical strength and long service life.

Noise

From 28 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.
