Integral Raised Floor Grommet


Applications

Designed to seal openings in new raised floor cutouts prior to the installation of communications or power cabling.

Based on measurements at multiple data centers, 50-80% of valuable conditioned air is not reaching the air intake of IT equipment due to unsealed floor openings. This lost air, known as bypass airflow, contributes to IT equipment hot spots, cooling unit inefficiencies, and increasing infrastructure costs. KoldLok products specifically address bypass airflow and its detrimental effects on data center cooling.

Item No. 1010
Integral Raised Floor Grommet
Item No. 3030
Split Integral Raised Floor Grommet
 


Benefits
• Increases existing cooling unit capacity
• Reduces the need to purchase additional cooling units
• Improves equipment reliability and extends equipment life
• Increases static pressure under the raised floor and improves cool air delivery through perforated tiles and floor grates
• Facilitates Cold Aisle/Hot Aisle best practices


Features
The Split Integral Grommets allows tiles to be moved without capturing cables. The Grommets integrate with the raised floor static dissipation system, providing 1 GigaOhm of resistance.

The Grommets contain no loose or partially fastened parts, which can become separated or fall through raised floor.

The Grommets are impact resistant and durable.

The Grommets satisfy NFPA 75 Section 5-4.4 requirement by self-dressing raw metal edges of raised-floor tile cable cutouts.

KoldLok products are compliant with Directive 2002/95/EC of the European Parliament and the Council on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment (RoHS).

Patented Sealing System
(U.S. Patent No. 6,632,999 and International patents Pending) Multi layer, opposing and interwoven filaments consisting of:

• 0.010 inch diameter upper filaments
• 0.020 inch diameter lower filaments
• Approximately 25,000 filaments per Grommet
• Static dissipative properties
• Premium-grade nylon Type 6 ensuring flexibility and self-sealing recovery


Sealing Effectiveness
• 100% bypass-airflow sealing in areas undisturbed by cable penetrations at static pressures up to 0.10 inches of water column
• 100% bypass-airflow sealing with four ½ inch cables penetrating the Grommet at the static pressure required to cool up to 3 kW/cabinet
• 96% bypass-airflow sealing with four ½ inch cables penetrating the Grommet at a static pressure of 0.10 inches.


Grommet Frame
The frame is molded from durable polypropylene.
Finish: Black


Floor Mounting System
