42U Adds Rittal's Liquid Cooling and PDU Products to GSA

Broomfield, CO – April 25, 2008: 42U (www.42u.com), the nation's largest, vendor-independent valued-added reseller of data center infrastructure solutions today announced that is has added Rittal to their GSA schedule.

With this addition, 42U's government customers can now have access to the industry's leading modular, scalable and comprehensive IT infrastructure solutions including enclosures, high-density cooling solutions and power distribution units. Included in the agreement are the following:

Rittal Liquid Cooling Package (LCP)
Developed to remove high levels of wasted heat from server enclosures, this high density cooling solution utilizes air/water heat exchangers to provide uniform, effective and affordable cooling for servers and similar IT equipment. The special horizontal airflow of the Rittal LCP represents an adaptation of this widespread cooling principle, providing cooled air uniformly throughout the complete height of the enclosure.

• LCP Standard
  Designed to be installed next to an 80" (2000 mm) high by 40"/48" (1000/1200 mm) deep TS8 server cabinet, the LCP Standard can accommodate up to three air/water exchanger modules that can be hot swapped if needed. When fully loaded with three air/water exchanger modules the LCP Standard can provide up to 68,243 BTU (20KW) of useful cooling with a maximum air volume of 1766 cfm (3000 m3/hr). Don't have an immediate need for that much heat removal? Start with one exchanger module then add more as needed.

• LCP Plus
  Using the same footprint and basic design as the Standard, the LCP Plus includes six fan modules that work in concert with the included heat exchanger to increase the useful cooling capacity to 95,540 BTU (28 kW). The LCP Plus is designed for cabinets 80" (2000 mm) high by 48" (1200 mm) deep and has a maximum air volume of 2825 cfm (4800 m3/hr). The LCP Plus (and LCP Standard) can be bayed to a single cabinet or between two enclosures. It is also possible to put a pair of LCPs on either side of especially hot cabinets for applications where extreme heat loads are present.

• LCP Extend
  Ideal for retrofitting, the LCP Extend is installed on the rear door of problem racks. The LCP Extend can be ordered for use on cabinets from other manufacturers. If you are already using Rittal cabinets, the unit comes mounted into the proper replacement rear door which allows you to simply swap it out with the existing rear door.

Rittal Power Distribution Units (PDU)

• Metered PDU
  Metered PDU products provide reliable power distribution for all the devices in your equipment cabinet, from 5,000 to 20,000 Watts. Metered units are available in 20 or 30 amps, 120 Volts or 208/240 Volts single-phase, and 208 Volts three-phase. Local input current monitoring allows the installation engineer to verify the combined load on the circuit or phase.

• Smart PDU
  The Smart PDU products provide reliable power distribution combined with remote power and environmental monitoring. Use the network interface to view power, temperature and humidity levels via a Web browser, or receive SNMP-based alarms when conditions exceed defined thresholds.

• Switched PDU
  Switched PDU products are Flagship PDU's with remote monitoring and management, including reboot commands for connected servers and network equipment. The Switched PDU products provide complete lights-out management of a data center and remote branch office. Switched PDU's combine remote configuration and management with power distribution and power and environmental monitoring.

Rittal TS8 Modular Industrial Enclosure
A revolutionary system designed specifically for demanding industrial applications. Featuring a 16- fold tubular frame and multi-level mounting, the TS8 boasts unsurpassed strength and flexibility. The robust tubular frame can hold weight loads up to 1,500 lbs on the mounting panel. The 25 mm hole pattern allows components and accessories to be mounted in three directions -- by height, width and depth - which provides maximum space utilization (up to 30% more available space than traditional NEMA style enclosures of equal dimension). The symmetrical frame design makes suiting in a row, into a corner or even back-to-back simple
