KoldLok Wave Split Integral Grommet
Applications
Designed to seal openings in new raised floor cutouts prior to the installation of communications, power, or other cabling.
In a study done by Upsite Technologies on 19 computer rooms totaling over 204,400 ft , it was found that 60% of valuable cooled air is not reaching the air intakes of IT equipment. The KoldLok Wave™ was developed to provide the best seal against this wasted bypass airflow.
Features
Sealing Effectiveness - New, patent-pending wave shaped thermoplastic elastomer offers the best sealing against bypass airflow, unsurpassed by any brush grommet on the market.
Usable Cable Area - Offers 45.5 sq inches of usable cable area, over two and a half times that of a leading brush competitor.
Maintenance Free - Wave shaped material seals around cables with no additional maintenance or monitoring required.
Configuration - Split design allows edge-cut tiles to be removed without capturing cables.
Fire Resistant - Thermoplastic elastomer material is rated UL94 HB.
Longevity - Durable, impact-resistant ABS frame.
Safety Cover - An optional cover is available to ensure greater safety before rack and cable installation.
Benefits
By sealing cable openings and blocking bypass airflow, the KoldLok Wave™:
- Increases cooling unit effectiveness
- Allows for greater IT density in data centers
- Increases static pressure under the raised floor
- Improves cool air delivery through perforated tiles and floor grates
- Decreases humidity control expense
- Meets a prerequisite for hot aisle/cold aisle best practices and containment strategies
- Reduces the need to purchase additional cooling units

Background
ELIMINATE BYPASS AIRFLOW
Unsealed cable openings allow 63% or more of bypass air losses in a
typical computer room. Excessive bypass airflow will reduce underfloor
static pressure to as low as 0.01" of water column. This is much
lower than the 0.025" required for cooling high heat densities
(> 1 kW/rack or cabinet). Unmanaged bypass air results in vertical
and zone hot spots and introduces significant cooling inefficiencies.
A CLEAR SOLUTION
The KoldLok Wave™ Split Integral Grommet automatically reseals raised-floor openings, permanently solving bypass airflow problems.
