Cubic industrial air cooler RN

New series of cubic industrial air coolers for medium and big storage cold rooms with volume from 200 to 3100 m3.

This range of air coolers has developed for heavy duty for cooling and storage of fresh or frozen food with temperature from -40 to +25°C. This innovative range of industrial air coolers, thanks to the wide choice of standard models and available accessories, satisfies any design and system requirement.

Air conditioning

Technical features

Air coolers suitable for fluids such as: water, glycol and brine.

1890 models.

From 1 to 5 fans.

Cooling capacity

From 13 to 315 kW

Fan-motors

Diameter 500 – 560 – 630 – 710 – 800 – 910 mm with aluminum 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, higher air throw and lower noise.

Fin spacing

4 – 6 – 7 – 8 – 10 mm

Casing

Casing in corrosion-resistant powder-coated aluminum or galvanized steel. Drip tray with welded corners and welded draining connection for a perfect seal. AISI 304 stainless steel screws.

Heat exchanger

The heat exchanger is made with 16 mm diameter tubes that ensure reduced pressure drops and reduced pumping energy consumption.

The high thickness fins guarantee greater heat exchange, superior mechanical resistance and long life.

Air coolers RNSG, with staggered tube arrangement and optimized ratio of finned (secondary) surface to tubes (primary) surface, enabling high specific cooling capacities.

Air coolers RNLG, with squared tube arrangement and a high ratio of finned (secondary) surface to tubes surface (primary), ensures lower dehumidification and less defrost cycles.

Defrost

Hot glycol, electric, light electric, water, combined defrost.

Options

Stainless steel tubes, stainless steel casing, stainless steel fins, Al/Mg fins, fans with stainless steel grids, coil coating, EC fans, ATEX fans, high pressure fans, shut-up, legs for floor installation, insulated drip tray, air streamer, inclined fans, collar for air distribution sock, fans wiring, fan ring heater, safety switches, insulated inlet hood, re-heating coil.
