The constantly increasing power losses of electronic modules make high demands on the effective cooling
of electronic modules. Large airflow volumes ensure secured heat dissipation, whereby higher airflow speeds reach the components, which leads to better heat transfer.

The space-saving 1 HU construction guarantees maximum installation space for our customers’ equipment.

The CoolBlast® fan unit from Knürr is available as a slot in unit with 3 and 6 fans for vertical ventilation of installed modules. The airflow required for cooling is primarily determined by the fan selection. Fans in three different performance classes are available (Standard, High, and Ultra High Performance).

To ensure that plenty of cooling air reaches the electronic components, CoolBlast® has an IP protective grid with high free cross-section surface.

  The Knürr CoolBlast® adjusts its cooling airflow to the power loss to be cooled. The temperature regulated control of the fan rotation optimises noise emission and the lifetime of the fans. The maximum reference temperature is set at the front.
A fan failure detector ensures high operational reliability. Exceeding the reference temperature is also detected in the same way. The fault signalling can be processed further with the rack monitoring system, RMS.

Optimum heat dissipation of the cooled module is attained with the high airflow volumes and pressure jumps in the CoolBlast® fan unit. Building-specific CFD simulations can optimise each customer thermal management application.

A number of other components and accessory parts are
also available for thermal management in server and network
rack systems.
