gENERAL cHARAcTERISTIcSCOOlSIDE EVO is a precision cooling system, in split-

system type, for application in modern IT infrastructure as

telephone exchange, data bank, internet hotel and server

rooms, all characterized by high thermal loads.

COOlSIDE EVO is able to cope the high density of

thermal load in a small space, up to 24.9 kW on 0.3 m2

of floor space.

The modularity of the system together with the adaptive

logic of microprocessor control make COOlSIDE

EVO the best solution for cooling racks and the latest

generation equipment.

For installation are not required underfloor plenum, ducts

or false-ceilings; the installation foresee the insertion of

COOlSIDE EVO within the rows of racks to cool.

This allows to contrast the localized heat sources (hot

spot) tailoring the installation to the actual situation of the

plant.

Another big advantage is the modularity and scalability of

the system, characteristics that allow for quick adjustment

and economic development of plant layout, according to

the changing needs of the infrastructure.

COOLSide evoair conditioning systems for high heat density racks

The COOlSIDE EVO system is designed to serve two main “server room” architectures currently in use:

- cooling system for rows of racks (hot/cold aisle) with units size B3 / B6.

- direct cooling of the rack (closed loop) with units size B3L / B6L.

All COOlSIDE EVO units can be equipped on request with dual power supply system (network + UPS) to ensure continuity

of service even during periods of blackouts.

COOlSIDE EVO is available in direct expansion (DX) version, to be coupled to a remote air cooled (MCAI) or water cooled

(MCWI) motocondensing unit, or for supply with chilled water (CW) produced by a liquid chiller.

The direct expansion version is equipped with an inverter controlled hermetic twin-rotary or scroll compressors, which

reduces power consumption in real time adjusting to the real plant thermal load.

The maintenance of the machines is as simple as possible thanks to the completely removable panels and complete access

to the front.

AN EffICIENT ENERGY USE

One of the most important characteristics of COOLSIDE EVO units is their high energy

efficiency, both at design and at the various operating conditions experienced during

the year.

The motocondensing units are equipped with inverter driven

compressor allowing proportional control of the cooling capacity,

while the axial fans electric motors are brushless type with built-

in electronic commutation system (EC). Moreover the condensing

section is equipped with a “microchannel” type heat exchanger

coil totally made in aluminium.

The evaporating units are equipped with plug-fan directly

coupled to brushless type electric motor with built-in electronic

commutation system (EC).

INVERTER SYSTEm

The compressor driven by an inverter varies the load continuously and

the regulation of the refrigerant circuit can be easily adapted, without

oscillations and transients, the operating conditions

required.

The system is highly efficient since it is supplying the

energy necessary to satisfy the required thermal load

only; furthermore it is possible to supply thermal or

cooling energy even in case of overload conditions of

the system. The working range of COOLSIDE EVO,

in comparison to the nominal values of cooling and

thermal capacity output, varies on average from 35% to 120%.

Motor rotation speed

PlUG fAN WITH EC ElECTRIC mOTOR

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.

ADVANTAGES Of THE “mICROCHANNEl TECHNOlOGY”

The micro-channel condensing coils are the ideal choice for operation with refrigerant pressures up-to 45 bar and they

are optimise on the motocondensing MCAI series with R410A refrigerant charge.

The micro-channel condensing coils are in aluminium and they are perfectly suitable for the civil and industrial

applications cooling, while the protection function of the oxide layer allows an optimum resistance to corrosion also in

case of aggressive ambient conditions.

The optional version with special protective surface treatment - acrylic painting TK Pro -

allows to obtain a high resistance to salt spray while maintaining

the same conditions of heat exchange capacity.

The use of aluminium for the micro-channel condensers

manufacture is able to offer the possibility for very light machinery:

the coil weight is only 50% compared to traditional copper pipes

and aluminium fins of the same capacity.

. The reduced air resistance of the micro-channel coils allows to

drastically reduce the fans motors electric energy consumption.

At the same performances conditions, the micro-channels

condensers require up-to less than 75% refrigerant when

compared to the traditional heat exchangers.
