Rittal blows cool

Rittal has announced the availability of RiCool, a new minimal height variable speed blower that provides effective cooling of densely packed VME or CompactPCI subrack systems.

RiCool, Rittal’s new minimal height variable speed blower, provides effective cooling of densely packed VME or CompactPCI subrack systems.

When mounted side by side in a subrack the RiCool blowers each give 220 cfm of airflow at 0″ static pressure. Air drawn up through the plug-in boards is then exhausted through the rear of the subrack via the backward curved impeller, using 1U of rack space.

At a static pressure 0.25″ of water, Rittal’s RiCool blower each provide over 90 cfm of airflow and continue to provide cooling at static pressures in excess of 1.0″ of water, exceeding the capabilities of 482.6mm (19-inch) rack mounted axial fan trays.

Rittal’s RiCool also offers an alarm output via fan speed sensor, speed control capability, long life, easy access and hot swap capability to use with no extra ducting. It is designed for normal operation below maximum speed and may be configured so that if one of a pair of blowers fails, the remaining fan accelerates to full speed to maintain effective cooling until a hot-swap replacement can be effected.
