Gas cooler flat RKS – RKL

New line of gas coolers for use in 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 features efficient heat transfer with reduced refrigerant volume even at low fan speeds.

Gas cooler with design pressure 120 bar
CO2 desuperheater with design pressure 60 bar

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

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

RKIS series CO2 desuperheater with short frame for more compactness or capacity for the same size.

RKIL series CO2 desuperheater with long frame for higher efficiency and lower noise.

Capacity

Gas coolers: from 9 to 580 kW

CO2 desuperheater: from 8 to 89 kW

Fan-motors

Diameter 500 – 630 – 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.

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 RKS and RKL 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.
