Polargy Launches New Data Center Rack Top Baffle
Polargy has announced a new addition to its PolarPlex line of containment solutions: the
PolarPlex Rack Top Baffle. This option for cabinet supported containment that provides a
significant reduction in both the installation and material costs of deployment.
PolarPlex Rack Top Baffles offer a tool-less magnetic attachment that enables data center
managers to increase airflow at the top of racks with minimal labor and cost-effective pricing. The baffles are well suited for data center owners and operators that need to deploy
open-top containment due to tall ceilings or constraints from fire suppression systems.
The modular Rack Top Baffles are also convenient for sites that reconfigure their layouts
frequently due to moves, additions, and changes.
PolarPlex Rack Top Baffles are comprised of an elegant anodized aluminum base, a set of
securing magnets, and either a vertical or angled lightweight panel insert. They are available in both standard sizes for easy ordering and custom sizes for unique data center configurations. With sizes up to
six feet wide, data center operators are now able to run a baffle across an aisle to create an endcap for full perimeter above-rack containment.
"PolarPlex Rack Top Baffles represent a new class of containment panels that are well-suited for projects where the
ROI goals are extremely aggressive," said Cary Frame, CEO of Polargy. "The baffles offer an investment option that can
be repurposed through the life of the data center, helping to provide optimized airflow for decades after installation."
Laird's Spindle Screw Pump Provides Higher Performance, Efficiency and Reliability for Liquid
Laird has developed a spindle screw pump that delivers consistent and reliable
performance in liquid cooling systems (LCS). Compared to centrifugal pumps,
Laird's spindle screw technology can pump fluids of higher viscosity without losing
flow rate, and pressure changes have little impact on pump performance. This is
vital in high G-force applications, such as a rotating gantry system used in a CT
scanner, as the pump is able to maintain constant flow and pressure while under
high G-force stress.
One of the most critical components in a liquid cooling system is the pump. Pumps
are in constant operation when the cooling unit is turned on and typically have
the shortest mean time between failure (MTBF) of all components due to friction
wear of bearings, pump blades and seals. If the pump fails prematurely, so will the LCS, causing the medical imaging
system to stop working. This can be a problem for medical equipment where hundreds of thousands of dollars per
day could be lost.
Laird's three-screw pump is comprised of a single rotor element that is powered, while two others are idle. Spindle
screw pumps move fluid axially without turbulence, eliminating foaming that would otherwise occur in viscous fluids.
The idle rotors are rotated by liquid pressure, essentially generating a fluid bearing, or hydrodynamic film, that provides radial support similar to journal bearings.
The self-priming spindle screw pumps allow an independent flexible positioning within the liquid cooling system.
Respective to the cost of ownership, the value of a highly reliable spindle screw pump is through long lifetime operation that can span over several years with minimal to no maintenance. This minimizes down time by eliminating the
need to turn off the end user system for pump replacement.
Long life operation is built into the spindle screw design due to no metal-to-metal contact between moving components. This minimizes friction wear and abrasions that can cause cavitation. The flexible mechanical assembly allows
the use of a smaller strainer with a higher mesh size that extends maintenance intervals and reduces the overall cost
of ownership. No metal-to-metal contact also eliminates pulsations, even at high flow rates, making the unit very
quiet during operation. The end result is smooth and quiet operation even at high revolution rates and pressure.
