KoldLok Mini - Models #10077

Applications

The KoldLok Mini is the same great KoldLok gromment, only smaller. Designed to seal small cable openings in the raised floor of new or existing computer rooms. Seals 4 x 6 inch Cable Openings.

Features

KoldLok is a permanent airflow sealing solution which will accept perpetual cabling¹ changes without requiring technician training, policing, or labor to cut, scribe, re-install, reposition, or modify any part of the grommet.

KoldLok is the best² low cost solution for achieving the hardware air intake temperature and humidity conditions required for maximum reliability and performance by computer and communication manufacturers.

KoldLok's sealing effectiveness enables standardization on one size of tile cutout reducing cost and tile inventory.

1 It is estimated that, on average, 25% of all raised floor openings are re-cabled quarterly.

2 Filaments are premium grade Nylon 6. Filaments made of styrene, ABS or polypropolene fall below KoldLok product standards.

Single-layer, opposing and interwoven filaments are 0.010 inch diameter with approximately 13,200 filaments per Grommet. Premium-grade nylon Type 6 filaments ensures flexibility and self-sealing recovery, and passage of 30-amp power connector.

The Grommet Frame is molded from durable PC/ABS.

Specifications

• Made with fire-rated resin and filaments that meet UL94 V0 standards
• Impact-resistant and durable
• RoHS compliant

Grommet filaments are premium grade Nylon 6 ensuring bristle flexibility, compliance, and selfsealing recovery. Filaments are conductive with static dissipation properties.

Grommet and filaments safely bleed off any static build up on cables passing through the cable opening caused by high velocity airflow (triboelectric effect). Grommet is an integral part of the raised floor¹s static dissipation system providing 1 GigaOhm of resistance.
br> Up to 98 percent bypass airflow sealing in areas undisturbed by cable penetrations at static pressures up to 0.10 inches of water column and up to 95 percent bypass airflow sealing with one inch cable bundle penetrating the Grommet both at the center and offset.

Installation

Seals 4 x 6 inch Cable Openings.

Overall size: 7 11/16" x 5 11/16" x 1 1/2"
Usable cable opening size: 5" x 2 1/2" *
Installation is Available
*Ensures easy passage of cable heads and power connectors including a 100 amp Hubbell™ power plug (or equivalent 4.125" x 4.125" connector).

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 Mini Raised-Floor Grommet automatically reseals raised-floor openings, permanently solving bypass airflow problems.
