Rack Cooler units direct expansion Dual Fluid
11,0 – 16,7 kW

The indoor vertical air conditioning units CLIMAVENETA RACK COOLER is an effective management system of the Hot Spots in the data center, ensuring low energy consumption and usage possibilities even under extremely high loads for HIGH DENSITY rack ´up and over 40 kW/m2 rack. The use of EC fan systems, featuring last-generation electronic-switching brushless motors, assures excellent performance and low consumption. The Rack Cooler Dual Fluid unit provides redundancy in cooling capacity also in emergency situations: to be connected to an external chiller for primary chilled water circuit, and to condensing unit i-HCAT for the secondary or back up circuit in direct expansion type. The condensing unit i-HCAT air-cooled type with axial-flow fans, fitted with INVERTER-DRIVEN HERMETIC SCROLL compressor for operation on R410A refrigerant, mounted on rubber vibration dampers, complete with oil charge, supplied with oil separator to ensure correct lubrication even at minimum speed, and fitted with thermal protector. The i-HCAT is available on versions BASIC ans d LT for low external temperature. PRINCIPLE OF OPERATION These individual units to be positioned between the racks in the row so as to act locally in order to dissipate the load of servers. In InRow versions (CCRC-I) by treating the air is sucked in the back of the unit directly from hot aisle of data center (35 ° C) to be cooled and sent on the cold aisle (18-20 ° C) in front of the racks. In Enclosure versions (CCRC-E) servers and conditioner are hermetically housed avoiding phenomena of mixing air with the outside, with obvious loss of efficiency in the conditioning. The air is sucked directly into the rack from the back closed directly by the servers (46 ° C) and sent from the front once cooled (25-30 ° C) directly to the servers with considerable savings of energy due to the smaller amount treated air.

Direct expansion Rack Cooler unit

The indoor vertical air conditioning units CLIMAVENETA RACK COOLER is an effective management system of the Hot Spots in the data center, ensuring low energy consumption and usage possibilities even under extremely high loads for HIGH DENSITY rack ´up and over 40 kW/m2 rack. The use of EC fan systems, featuring last-generation electronic-switching brushless motors, assures excellent performance and low consumption. Available as standard with the dynamic management of N +1 EC fans to optimize consumption and redundancy of the cooling system. Coupled with outdoor condensing unit i-HCAT air-cooled type with axial-flow fans, fitted with INVERTER-DRIVEN HERMETIC SCROLL compressor for operation on R410A refrigerant, mounted on rubber vibration dampers, complete with oil charge, supplied with oil separator to ensure correct lubrication even at minimum speed, and fitted with thermal protector.

PRINCIPLE OF OPERATION These individual units to be positioned between the racks in the row so as to act locally in order to dissipate the load of servers. In InRow versions (CRC-I) by treating the air is sucked in the back of the unit directly from hot aisle of data center (35 ° C) with significant benefits from the point of view of energy efficiency and cooling capacity, to be cooled and sent on the cold aisle (18-20 ° C) that is in front of the racks where it is sucked by the same. In Enclosure versions (CRC-E) servers and conditioner are hermetically housed within the same Rack closed structure thus avoiding phenomena of mixing air with the outside, with obvious loss of efficiency in the conditioning. The air is sucked directly into the rack from the back closed directly by the servers (46 ° C) and sent from the front once cooled (25-30 ° C) directly to the servers with considerable savings of energy due to the smaller amount treated air.
