Kaparel/Rittal announces the introduction of the new RiCool II blowers being installed in their AdvancedTCA Shelf. The major difference between traditional and the new generation of telecommunications equipment is greater heat release and a large footprint. AdvancedTCA Shelves are targeting 2.8KW for a 14-slot shelf and 3.2KW for a 16-slot shelf resulting in equipment frames with a total release of over 10KW.

“Removing 200W per slot (2.8KW) from an AdvanceTCA Shelf at 40°C ambient at approximately 65dBA with a serviceable Field Replaceable Unit (FRU) solution was the goal at Kaparel/Rittal. We feel comfortable that we have been able to achieve this and will support this with a full simulation and actual measurements that are now being take”, comments Eike Waltz, T echnical Manager at Rittal.

The RiCool II blower was designed for higher heat generating boards in applications for the Kaparel/Rittal AdvancedTCA Shelf. Its predecessor the RiCool I was designed for VMEbus and CompactPCI applications with heat loss factors from 30W up to 70W/slot (21-slots).

RiCool II is positioned for the AdvancedTCA Shelf applications with heat loss of 200W/slot to move air effectively and efficiently through densely packed subracks using only 1U of rack height. The RiCool II is available in 48V for the Kaparel/Rittal AdvancedTCA Shelf and is hot swappable for fast and easy maintenance.

Commenting on the RiCool II product Mike Peters, Kaparel’s Director of Sales, “Kaparel/Rittal is getting a great deal of enthusiastic feedback from customers about the cooling ability of the RiCool II blowers in our AdvancedTCA Shelf in their applications.”

The RiCool II blower and AdvancedTCA Shelf will be showcased in the Kaparel/Rittal booth # 4311 at ElectronicaUSA/Embedded Computer Show in San Francisco March 30 to April 1, 2004.
