The KoldLok® Mini Split Integral raised floor grommet seals small, 4″ x 6″ (100mm x 150mm) cable openings in new or existing raised floor environments. Designed with virtually all of the original KoldLok® engineering, the KoldLok® Mini Split Integral floor grommet is positioned at a lower price point. Based on measurements at multiple data centres, between 50% – 80% of conditioned air is not reaching the air intake of IT equipment due to unsealed floor openings – some as small as 4″ x 6″ (100mm x 150mm). This lost air, known as bypass airflow, contributes to IT equipment hot spots, cooling unit inefficiencies, and increasing infrastructure costs. KoldLok® raised floor grommets are designed to reduce bypass airflow and improve data centre cooling.

  • Designed to seal small cable openings in the raised floor of new or existing computer rooms. Based on measurements at multiple data centres, on average 60% of valuable conditioned air is not reaching the air intake of IT equipment due to unsealed floor openings – some as small as 6 x 4 inches (152 x 102mm).
  • 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 centre cooling.
  • Smaller size 6” x 4” (152 x 102mm) offers flexibility for data centres that have multiple cable opening sizes.
  • Meets smaller cable opening standards specified in new data centre builds.
  • Cost-effective method of separating data cabling from power cabling.
  • Contains no loose or partially fastened parts that can become separated or fall through the raised floor.
  • The grommets are impact-resistant and durable.
  • Satisfies NFA 75 Section 5-4.4 requirement by self-dressing the raw metal edges of raised floor tile cable openings.
  • 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).

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 grate.
  • Facilitates Cold Aisle / Hot Aisle best practices.

Patented Sealing System
(U.S. Patent No. RE41863 and International Patents Pending) Multi-layer, opposing and interwoven filaments consisting of:

  • 0.010 inch diameter.
  • Approximately 13,200 filaments per Grommet.
  • Premium grade nylon Type 6 ensuring flexibility and self-sealing recovery.
  • Ensure passage of 30 amp power connectors.

Sealing Effectiveness

  • Effective bypass airflow sealing in areas undisturbed by cable penetrations at static pressures up to 0.10 inches of water column.
  • Effective bypass airflow sealing with one inch cable bundle penetrating the Grommet both at the centre and offset.

Grommet Frame

  • The frame is molded from durable PC /ABS.
  • Finish: Black.

Floor Mounting System

Four (4) self-drilling screws are provided for installation.
