Standard Features and Options The modular, row-based computer room cooling system offers efficient, predictable, and economical cooling for a variety of spaces. Critical environmental requirements now reach far beyond the confines of the traditional data center or computer room to encompass a larger suite of applications, referred to as technology rooms.
Standard Features All series: • Variable-speed fans • Remote shutdown input • Common alarm output • Internal condensate pump • Top or bottom piping • Network Management Card (NMC) • Remote temperature sensors • Microprocessor controller • Insulated cabinet ACRD100 series and ACRD200 series only: • Washable filter • Condensate management with two dual floats • Condensate pumps • Scroll compressor • Hot gas bypass • 2-way/3-way floating point valve (ACRD200 series only) • Liquid line solenoid valve (ACRD100
Accessories • Cable leak detector • Baying kit-InRow DX to NetShelter VX rack • NetShelter SX 42-U to 48-U height adapters • NetShelter VX 42-U height adapters • Bridge trough power cable shield • Data cable bridge partition • Isolation ball valves (ACRD100 series only) • Fluid cooler • Condenser • Aisle containment • Rack containment 4 InRow™ Direct Expansion Air Conditioners Technical Specifications 990-4617
Scalable Solution for Critical Environments InRow Advantages The row-based solution improves energy efficiency and cooling ability in a number of ways. First, the InRow DX draws air directly from the hot aisle, allowing the InRow DX to take advantage of higher heat transfer efficiency due to higher temperature differences. It can then discharge room-temperature air directly in front of the servers it is cooling.
Cabinet The frame is constructed of 16 gauge formed steel for maximum strength. The cabinet is serviceable from the front and rear. All exterior panels and corner posts on the frame are powder coated for durability and an attractive finish. The front and rear exterior panels are constructed of 18 gauge perforated steel with 69.5% open free area. All panels, which include a key latch for safety and security, allow easy access and removal. Insulation (ACRD100 and ACRD200 series only) is 80.
Condensate pump ACRD100 and ACRD200 series: A condensate pump is factory wired and piped internally to the condensate drain pan. The pump is capable of pumping 34 l/h (9 g/hr) against head pressures of up to 50 ft (15.2 m) of total run. Of that run, 16 ft (4.9 m) can be vertical lift as measured from floor level. Dual floats are included with the unit. One float is used for condensate pump control, and the other float generates a condensate pump failure alarm.
Optional Features Cable water detector A leak detection cable is placed on the floor or subfloor around all possible leak sources. If water or other conductive liquids contact the cable anywhere along its length, the microprocessor controller announces the leak visually, audibly, and across the network. The 6.1-m (20-ft) cable may be cascaded to make custom lengths up to 24.4 m (80-ft). Network cable Various lengths of network cable are available to ship with your cooling system.
Hot Aisle Containment System Modular ceiling tiles and doors can be used to enclose the hot aisle. This increases the densities that can be handled in a single rack enclosure by eliminating mixing of hot and cold air streams. This method, called load neutralization, removes the heat from the hot aisle, cools it, and then returns it to the surrounding room area at or slightly below room temperature.
