PLENAFORM® Plenum Baffles

assembly03.gif

PLENAFORM® is a flexible, snap together, air flow baffle system which directs or diverts air flow under raised floors.

The PlenaForm® Baffle System is a flexible, snap together, air flow baffle system which helps to solve dynamic thermal imbalances in data centers. Installation is easy, and the system does not require electricity to operate. It is a holistic tool to direct or block airflow very simply and inexpensively. And if necessary, relocating is easy: just release the cable ties.

Benefits

  • Overcome challenges in data center cooling
  • Reduce energy consumption and operating costs
  • Keep employees more comfortable

 

Suggested Applications:

1. Console operations located on the raised floor? Partitioning off under Control Centers improves operator comfort. This is a before picture (note the winter coats & hats).

Before Plenaform

2. Zone your room for less. Partition off vacant data center space. If you wall off a section of the data center because you are building a NOC or because it is unused, there is no need to pump air under the floor. Even if there are no perforated tiles you will leak air unnecessarily.

   

3. Easily cool a hot spot with PlenaForm dedicated airflow 'partitioning'. Static pressure is increased delivering a higher volume of cooling through perforated tiles at a further distance from the CRAC units. To maintain velocity pressure to particular ‘hot zones’, PlenaForm partition baffles help maintain the static pressure further away from a CRAC unit. They can be used as “flow guides”, that is, they can be used to create cool or hot spot channels within the plenum to direct the flow to specified regions.

4. Guide the cold air and keep it "fenced" in. Seal off perimeter corridors and walkways so that more concentrated cold air is dedicated for the equipment areas.

5. Create dedicated cold aisle partitioning to maintain air velocity pressure further away from the CRAC units. Position perforated floor tiles in the cold aisles in front of the server racks. Racks should be lines up in alternating rows with cold air intakes all facing one aisle and hot air exhaust facing the other. This separation of hot and cold air provides better uniformity of air temperatures, which can boost overall facility efficiency.

   

6. Optimize your cooling. Seal off unused space that does not require chilled pressurized airflow. Without dedicated partitioning, as the air moves further away from a CRAC unit, the air velocity decreases.

7. Seal off under non-transformer based PDU’s.

8. Install inside servers racks to stop lateral heat transfer.

SUMMARY

The key to controlling the airflow distribution is the ability to influence the pressure distribution (or the flow field) in the plenum. For specified (horizontal) floor dimensions and total flow rate, the pressure distribution is governed by the following parameters:

  • Plenum height
  • Open area of perforated tiles
  • Distribution of open area on the floor
  • Relative positions of CRAC units and perforated tiles
  • Presence of under-floor blockages
