Climate control for Modular Safe/Modular Safe Extend System accessories Page 537 Modular Safe/Modular Safe Extend Page 505/506 ● All climate control units are designed as split units to ensure hermetic separation between the cooling circuits inside and outside of the safe. This prevents the ingress of dust and corrosive gases. ● Air routing inside the safe is horizontal. The hot air is drawn in at the rear, and the cooled air is expelled in front of the 482.6 mm (19˝) level. Compact climate control Suitable for use in rooms with climate control in the building or adequate ventilation, and low or no noise level requirements. The climate control unit is available in the output categories 2.5 kW and 4 kW. The evaporator coil is fastened to the side panel on the inside of the modular safe, and the external device on the service door (Modular Safe Extend) or side panel (Modular Safe). Outdoor climate control When using the outdoor variant, the internal circuit of the climate control unit is secured to the side panel on the inside of the safe. The external unit is positioned outside of the building. The internal and external units are connected to one another via coolant lines and control cables. The hot air from the servers is drawn in at the rear of the safe, and the cooled air is expelled in front of the 482.6 mm (19˝) level. Benefits of the outdoor model: The waste heat is routed directly to the outside. As a result, room ventilation or air-conditioning is not necessary. Outdoor climate control solution with inverter technology The external unit with inverter technology allows targeted speed control of the compressor. The volume of refrigerant is regulated via the electronic expansion valve. Adaptation to cooling requirements facilitates energy savings of up to 40%. The cold air is expelled in front of the 482.6 mm (19˝) level by the internal unit (evaporator coil), while the hot air is drawn in at the rear. Modified air baffle plates achieve additional efficiency gains and help to avoid hot spots.
