Passive Airflow Management

Passive Airflow Management

Passive airflow control products are used for optimizing airflow in "front-to-back" airflow applications to minimize bypass airflow. Their application is recommended for efficient cooling of the installed equipment that requires front-to-back airflow. In order to create an efficient cold zone, we recommend the use of a separation frame, blank panels and, in cases of cold air supply from below the rack, a bottom deflector.

Successful air flow management and optimization also requires the application of blank panels into all unused rack Units(RU) to prevent by-pass of cooled air. Double layer brush grommets are also highly recommended for all openings to prevent by-pass air-flow and help maintain static pressure within the raised floor. Application of products mentioned on this page can vary depending on the particular design specifications and equipment or facility requirements. Please do not hesitate to contact us with any questions. We will help you to design the correct solution for the cooling of installed equipment, including efficient air flow management (presales[at]conteg.com).

 

Separation frame - DP-RSF-CW, DP-ROF-CW, DP-RxF-CW
The Air Separation frame is used for minimizing by‑pass airflow between racks hot and cold zones. Using an Air Separation frame in a Room Feed with Plenum Return deployment forms a “cool zone” inside the rack between the front door and the equipment mounted on the 19” profiles. Cool zone depth is recommended to be 150 mm. This depth is defined as distance between front of the extrusion and front of the rack. Solutions with different depths are available ‑ 50, 100 and 200mm. Solution for 50 mm depth is universal and use rubber material for sealing. 

Modified version of Air Separation frame allows a simple installation of the frame inside the rack and consequentially joins two racks together. This version of separation frame is compatible with the new QUICK Connecting Kit ‑DP‑DR‑UNI‑Q. When both products are used together is it possible to use pre‑installed Air Separation frames directly from producer or system integrator. Bolting of racks together on the site is a tool‑less operation that can be carried out by one installer only.

To asure proper functionality of the Air Separation frame in the ROF or RDF racks width 800 mm the HVMP/HVMF holders or extrusions type C or P (with blank panels) must be used.

  • Air Separation Frame designed for application in ROF, RDF, RSF rack series, 600 and 800mm wide and 42, 45 and 48U high
  • Installation in front of 19" vertical extrusions
  • Air Separation Frame depth 150mm and 50 mm

 

AIR FLOW Deflector - DP-AFD-ROF, DP-AFD-RSF

The deflector is located in the bottom part of the rack and is used to leads the cold air from the raised floor space directly to the cold zone in the front part of the rack. Deflectors are designed ‑ for RSF/RDF and ROF racks. The ROF version designed for 600 or 800mm wide racks and can be installed into all ROF family racks of anz depth – from 600 to 1 200mm.  Deflector helps control air-flow rates or shuts the air supply off if no equipment is fitted into the rack. The RDF/RSF version does not take up 19" space and can be installed in lieu of the front part of the rack's bottom cover.

CHIMNEY - DP-HPR

The Chimney is designed to form a duct for the hot exhaust between the rack and the hot plenum. The Chimney  is  constructed from a 1mm thick powder-coated sheet steel and comes with gasket kit to ensure there is optimum sealing between the rack and the hot plenum. The Chimney's height can range from 750 to 1 360 mm, depending on your site requirements. The Turning Vane is part of the Chimney solution. It is designed to enhance the natural draw effect of the Chimney and allows for the passage of cabling and power cables. Constructed from a 1 or 2mm thick powder-coated sheet steel, the clever design of the Turning Vane allow for optimum air flow. The Turning Vane requires a minimum of 200m offset on the rear extrusions.
