Overview

Knurr CoolBlast Fan Unit

Designed for use with Knürr Miracel racks the Knürr CoolBlast® Roof Mount Fan Unit is suitable for roof or door installation. The fan unit moves warm air out of the rack and avoids overheating.

The Knürr CoolBlast Roof Mount Fan Unit is available with 2, 3 or 6 fans in 3 different versions

  • unregulated;
  • thermostat-controlled; and
  • speed-controlled.

The speed-controlled version adjusts its cooling airflow to suit requirements and optimises noise emission and power requirements; extending the lifetime of the fans. The maximum reference temperature is set at the front. A fan failure detector ensures high operational reliability with the option of processing the fault signalling with the rack monitoring system (RMS).

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