1. Based on standard 2U server: HP DL 580 G5
2. Module weight includes all components, minus IT racks and IT equipment
3. Assumes a 1:1 ratio (electrical power load: cooling load)
4. Assumes a 65°F chilled water source and a max allowable cold aisle temperature of 95°F Lower temperature water produces much greater cooling performance.
5. Assumes the use of a refrigeration cycle to provide source water at 65°F
6. Assumes only the parasitic losses associated with on-board fan motors
7. Includes fire suppression, electrical termination, hydraulic termination equipment and controls

Silver Linings Features

Silver Linings Features A. Interior Track Lighting (optional) B. Equipment Power Access, to customer specification C. Coolant Tubes beneath flooring isolate equipment from fluids and enhance operator safety. D. Multi-unit Fan Panel and E overhead, powered Cooling Ducts create "Augmented Convective Cooling" across full face of equipment racks. F. Heat Exchanger Core produces patented airflow pattern that cools better than conventional coil systems. G. Equipment Racks — contents determined by customer specification H. Moveable Equipment Base provides access to either side of racks, and maximizes rack size. I. Steel Flooring Joists and Fork Pockets provide quick, easy and safer movement of modules. Available in Standard-size Modules — for ISO container housings — or custom configurations.
