INTRODUcTIONThe NEXT EVO CW series air conditioners are the

best answer to the need of a precise control of the

thermo-hygrometric and air purity conditions in the

modern and sophisticated Hi-Tech installations,

granting the optimal environment for electronic

equipment to work in and operators wealth.

Data centres, telephone exchanges, internet

hotels, museums are just some of the typical

applications of NEXT EVO CW units, whose

efficiency, silentness and versatility features are

appreciated by the most qualified users worldwide.

AN EffICIENT ENERgY USE

One of the most important characteristics of NEXT EVO CW machines is

their high energy efficiency, both at design and at the various operating

conditions experienced during the year.

The fans electric motors are the brushless type with built-in electronic

commutation system (EC) which yield high energy savings during

operation in reduced air flow.

These electric motors are ensuring high performances, minimum energy

consumption and total absence of electromagnetic noise

fREE-COOLINg

The free-cooling system is an

important accessory that allows you

to maximize energy savings of air

conditioning plant

The microprocessor controls a dual

source free-cooling system: direct

free-cooling with direct introduction

into the room of ambient air, or water

indirect free-cooling with a dedicated

heat exchanger.

According to the set-point and the

energy saving logic the controller

activates the free-cooling system

more affordable.

THE RC gROUP TECHNICAL SYNERgY IN ENERgY CLASS “A”

RC Group proposes itself as the sole supplier of

offering both the air conditioning units and the

liquid chillers.

The synergy includes the air conditioners NEXT

EVO CW and the air-cooled liquid chillers series

UNICO TURBO FL.

These liquid chillers are equipped with oil-free

two stage centrifugal compressors with magnetic

levitation bearings, flooded shall and tube

evaporator and micro-channel type condensing

coil.

The 17 proposed models cover cooling capacities

from 280 to 1500 kW, all in energy class “A” with a value of 5.76 ESEER

DENSITY

up to 72,0 kW/m2

The layout optimization of

components and accessories

makes the NEXT EVO CW PLUS air

conditioners able to grant a high

cooling density for those situations

where the space organization is a key-

factor.

The machine is divided in two

sections:

the upper part (“A” in the picture)

includes the high efficiency air filters

and the air handling section with a

cooling coil available in 3 versions:

with 4, 6 or 8 rows.

The lower part (“B” in the picture) can

be placed in the compartment formed

by the raised floor and includes the

plug-fans.

The lower part is also provided with

height-adjustable feet to allow the

adaptation of the frame to the height

of the raised floor.
