CoolBlast® fan unit

Double the Cooling Power – Serious Sound Reduction – Power as Required
 
Modularity
Selection according to the required volume flow.
Adaption is made specifically via fan selection according
to three performance classes:
• Standard Performance (axial fan)
• High Performance (axial fan with high speed rate)
• Ultra High Performance (diagonal fan)
     
   
Grid (optimised according to airflow)
• With very low pressure loss, so that high cooling
  power of modules is guaranteed
• Contributes to considerable noise reduction
  (depending on design and construction)
   
   
Thermostat
• Unit is switched on and off thermostat-controlled
• Adjustable according to required temperatures
   
   
The CoolBlast® fan unit from Knürr is available as fan plug-in for vertical cooling of modules with 3 and 6 fans. 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). Selection can be made between quiet axial fans and special diagonal fans with an especially high support rate for cooling air.
   
   
To ensure that plenty of cooling air reaches the electronic components, CoolBlast® has an IP protective grid with high free cross-section surface. The grid form minimises the pressure loss of the streaming airflow and reduces
the streaming noise.
   
   
The Knürr CoolBlast® adjusts its cooling airflow to the power loss to be cooled. The temperature-regulated control of the fan rotation optimises the noise emission and the lifespan of the fans. The maximum reference temperature is set at the front. A fan failure detector ensures high operational security. Exceeding the reference temperature is also detected in the same way. The fault signaling can be connected with the rack
monitoring system, RMS.
A simple thermostat-controlled model is also available.
   
   
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.
   
   
Air conduction components, optional with filter, round off the product range. The filter mat protects the electronics in use against dirt and dust and can be changed during running operation.
In addition to the CoolBlast® fan unit, a number of other components and accessory parts are also available for rack thermal management.
