Directional Airflow Grilles

These have been designed to direct the airflow toward the server rack to significantly reduce bypass air and to evenly distribute airflow across the full height of a standard 42U rack. A bi-directional grille is designed to divide the airflow evenly in two directions to provide even distribution to racks on both sides of a cold aisle.

  • High Capacity Airflow Panels                                                                                                            Up to 68% open area directional airflow panel, with effective cooling capacity up to 14kw at 15Pa, and 93% capture index.  Physical characteristics include static design load rating of up to 11Kn, and rolling load rating of 6.9Kn.
  • 25% & 32% directional perforated panels                                                                                       Cool the same load as vertical plume panels with nearly half the airflow volume.  In uncontained spaces the 32% grille provides nearly the same cooling capacity as a standard 56% open area grille using about half the airflow.

Air Volume Control

Automatic damper control

Datacentres rack loads frequently change on a minute-by-minute basis due to inconsistent processing demands and equipment upgrades. This load variability has been driven by the improved efficiency of IT hardware over time, increasing the difference between idle power consumption, and 100% utilization. This fact, coupled with the growing use of cloud computing, makes manual tuning of the airflow at the panel level impossible.

By matching cooling to the IT load at the rack level the wasted energy that results from designing to peak load can be eliminated. By delivering only the right amount of air required to cool the rack a savings of over 40% in fan energy can be realized.

Manual damper control

Some datacentre’s experience very little load variability however, the typical datacentre environment is not comprised of a single rack density level. In fact, it would be near impossible to find two racks which consume exactly the same amount of energy in a large datacentre. This load diversity results in differing airflow requirements per rack. Efficient cooling requires that the airflow delivered to each rack be matched to that rack’s demand.

Each rack in the datacentre is a constantly changing entity, each add, move or change modifies the load. This changes the rack’s airflow requirements, resulting in the need to adjust the airflow delivered from each panel to properly and efficiently cool the rack.

Options include: Single, Dual & multi-zone zone dampers; opposed blade dampers &Slide dampers.

Power-assisted airflow

A fan assist module is designed to provide a blast of cooling through an individual airflow panel. The fan automatically turns on when conditions require additional cooling. Options are available to utilize rack mounted temperature sensors or an existing client sensor network to control the fan. Equipped with a variable speed drive the fan can be throttled up or down based on the heat load requirements. This powerful solution is capable of cooling up to 20kW of IT load per unit for solving the toughest hot spots.

Containment efficiency

Close all open apertures in the floor where typically cable access or mechanical services have been fitted to maintain optimum floor pressure and supply air distribution through floor grilles; as recommended in the EU Best Practices for Datacentres.

Solutions include: Floor grommets, airguards and brush-strips.
