COOLSIDE EVO CW

Main features
COOLSIDE EVO is a precision cooling system 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. 
The COOLSIDE EVO system is designed to serve two main "server room" architectures currently in use: the cooling system for rows of racks (hot/cold aisle) and the direct cooling of the rack (closed loop). 
All COOLSIDE EVO units are equipped with dual power supply system (network + UPS) to ensure continuity of service even during periods of blackouts. 
Version for supply with chilled water (CW) produced by a liquid chiller.

Access doors. The doors are equipped with handle with security lock. 
Colour: 
- Similar to RAL7015. 
Air flow: 
- B3 / B6 size – Cooling system for rows of racks: 
o Air intake from the back side through honeycomb type grille and frontal air delivery through honeycomb type grille. 
- B3L / B6L size – Direct cooling system of racks: 
o Air intake from side through honeycomb type grille and air delivery from side through honeycomb type grille. 
FILTER SECTION 
Washable air filters with G2 efficiency, with cells in synthetic fiber, on air suction panel. 
Differential pressure switch on the air side for clogged filters signal. 
COOLING SECTION 
Heat exchanger coil with internally corrugated copper tubes and high efficiency aluminum fins, specifically developed to provide high heat transfer and lower pressure drops. 
Frame in galvanized steel. 
2-way modulating valve for water flow regulation with 0÷10V servomotor and emergency manual control. 
Hydraulic connections arranged for connection from bottom side of the unit. 
Condensate tray in peraluman. 
FANS SECTION 
Centrifugal fans with backward curved blades, single suction and without scroll housings (Plug-fans), directly coupled to brushless type synchronous EC motor with integrated electronic commutated system and continuous variation of the rotation speed. The motor rotation control is obtained with the EC system (Electronic Commutation) that manage the motor according to the 0÷10V proportional signal coming from the microprocessor control. 
Fans quick installation system for a fast replacement. 
#2 temperature sensors on air delivery. 
Temperature sensor on air intake. 
Current detector for loss of air flow alarm. 
ELECTRICAL PANEL 
Extractable electrical panel, in accordance with EN60204-1 norms, complete with: 
Power supply with 10A plugs. 
Magnetothermic switch on power supply 
Terminals for external enabling, smoke/fire alarm, general alarm and LAN connection. 
Power supply: 230/1/50 
CONTROL SYSTEM 
Microprocessor system with graphic display for control and monitor of operating and alarms status. The system includes: 
- Voltage free contact for remote general alarm. 
- Main components hour-meter. 
- Non-volatile “Flash” memory for data storage. 
- Menu with protection password. 
- LAN connection. 

OPTIONAL ACCESSORIES – COOLSIDE EVO CW 
B3L / B6L size – Cooling system for rows of racks: 
- Air intake from the back side through honeycomb type grille and frontal air delivery through honeycomb type grille. 
Condensate drain system that includes pump with activation float, 4 linear meters long discharge pipe and high water level alarm. 
Floor water presence alarm through sensor to be placed on the floor. 
Additional underfloor water sensor kit.
