PLANT TYPECOOLING SYSTEM FOR ROWS OF RACKS (hot / cold aisle)COOLSIDE EVO units are placed in the rows of racks that are arranged so as to obtainalternate cold and hot aisles.Electronic equipments contained in racks independently provide to aspire the necessary airfor cooling.
- In the hot aisle rack expels the hot air used to cool the electronic components whileCOOLSIDE EVO draws the hot air to be cooled.- In the cold aisle COOLSIDE EVO blow the filtered and cooled air while the rack
draws cold air to cool the electronic components.

COOLSIDE EVO DX + MCAI direct expansion system (mono-split or multi-split system)
The LAN network is used to connect external motocondensing unit to their internalevaporating units. It is not possible to carry out the LAN connection to the other system of theplant.
Each indoor unit is equipped with terminal having graphic display and keyboard. The externalmotocondensing unit is not equipped with terminal. All operating parameters are still visibleand can be set by each terminal of the indoor units.However, there is a RJ45 socket on the condensing unit's electrical panel for connecting aterminal to the personnel of the service.Hardware interfaces for connection to building management systems (BMS) are optionalaccessories of the motocondensing unit and are installed in the electrical panel.
