Micro Data Centre System accessories Page 507 Micro Data Centre Page 466/467 ◾ Separate, hermetically sealed internal and external circuits ◾ Dust and flue gases are unable to ingress ◾ The internal and external unit are connected to one another via refrigerant lines and control cables and shielded for fire protection ◾ Air routing in the Micro Data Centre is horizontal. Modified air baffle plates ensure targeted air routing. By separating the “cold side” from the “hot side”, air short-circuits are avoided, and the efficiency of cooling is enhanced. ◾ Suitable for use in rooms with climate control in the building or adequate ventilation, and low or no noise level requirements. The evaporator coil is fastened to the side panel on the inside of the Micro Data Centre, and the external device on the service door.
