Schroff GmbH, one of the leading manufacturers of electronic packaging systems, will present new products for the equipping of data centres at this year's CeBIT from 3 to 8 March 2009 in Hannover. Alongside a concept for hot and cold aisle containment based on components of the VARISTAR cabinet platform, the company is demonstrating a new room-independent cooling system capable of dissipating up to 40 kW of waste heat per cabinet. Schroff will also exhibit its complete range of network and server cabinets and associated accessories such as new intelligent socket strips.

Schroff's containment concept can substantially increase the cooling efficiency of a computer room, with a corresponding reduction in energy costs. This increased efficiency is achieved by separating the hot and cold airflows consistently from one another. Schroff has based its cold or hot aisle containment on modified elements of the VARISTAR cabinet programme. The VARISTAR frame profile with its 45° angled surface and typical meander-style grid holes offers many universal fixing options. The powder-lacquered frames in steel plate with protective safety glass link the opposing rows of cabinets and close the aisle from above. Doors are fitted at each end of the aisle to seal it completely. These doors can be swing doors, sliding or revolving, electric or mechanical, with or without lock and with motion signalling. Schroff containment elements can be mounted or retrofitted simply on the various different types of cabinet.

For particularly high cooling requirements Schroff is offering a new cooling solution with its VARISTAR LHX 40 as an optimally-matched complete cabinet solution. The new air/water heat exchanger is capable of removing up to 40 kW of heat dissipation per cabinet. The heat exchanger has a closed air loop with an airflow volume of up to 4200 m³/h. The exhaust temperature to the servers can be adjusted in 0.1 degree increments from 18 to 30 °C. Mounted laterally to right or left in a 1200 mm deep cabinet, the heat exchanger provides a homogeneous air distribution throughout the entire 19" mounting height using seven fans that can be replaced during operation, thus assuring a uniform cooling of all systems mounted in the cabinet. Fixed connectors on the rear of the fan modules make them quick and simple to replace when necessary. The fans blow the cold air directly into the inlet area of the servers. With the width of the air/water heat exchanger being only 200 mm, an 800 mm wide cabinet is sufficient for this cooling solution. The result is a reduced space requirement in the data centre compared to similar systems on the market.

The new 3-phase 19" power distributor and single-phase socket strips with Wieland connections thus allow 3-phase power distribution to be set up inside the cabinet. Single-phase consumers can also be connected directly to the 19" power distributor. The distributor has an input voltage of 400 V_AC at 32 or 63 A. Outlets with IEC 60320 C19 sockets are provided at the rear. The 32 A model features 6 x 230 V_AC,16 A outlets and the 63 A version has 9 x 230 V_AC, 16 A.

Schroff has also expanded its range of intelligent socket strips. Alongside single-phase units, now 3-phase telemonitored and remote-controllable socket strips are available with C13 and C19 sockets, conforming to IEC 60320. The socket strips are fitted with hydraulic-magnetic circuit breakers. The power, current and voltage of either the entire strip or of each individual socket insert are monitored. Local monitoring via a display is possible in addition to telemonitoring. The remote-controlled on/off switching of the individual inserts can also be sequentially programmed. By combining these intelligent socket strips with 19" power distributors and additional sensors in one cabinet, a redundant power supply system including cabinet monitoring can be created. Various sensors compatible with the intelligent socket strips are available (temperature, humidity or temperature plus humidity) that are inserted into a socket strip and may be positioned in the desired part of the cabinet.
