4 Kinds of Koldlok Floor Grommets for Your Data Center

A quality floor grommet is essential to any data center, as grommet solutions fill cable openings in raised floor systems and prevent wasteful airflow. And just as you can customize a data center according to hot and cold aisle containment, you can also customize the floor grommets. Here are four kinds of grommets to consider when it comes to installing in your data center.

Surface Mount Data Center Raised Floor Grommets

Surface-mounted grommets lock in many raised floor tile cutouts in existing data centers and support flexibility when it comes to getting rid of the tiles without capturing the cables. According to studies at many data centers, almost 50 percent of valuable conditioned air does not reach the air intake of IT equipment because of the floor openings being unsealed. Air is lost, and this bypass airflow adds to hot spots in IT equipment, cooling unit challenges, and blowing up the costs of infrastructure. Koldlok devices aim at fixing this airflow problem and addressing its consequences.

How does it do this?

  • By increasing the existing cooling unit capacity
  • Limiting the need to buy additional cooling units
  • Enhancing equipment reliability and elongating its life
  • Boosting static pressure beneath the raised floor and promoting cool air delivery through punctured tiles and floor grates
  • Supports Cold Aisle/Hot Aisle best practices

Integral Mount Drop-In Data Center Raised Floor Grommets

The Integral Mount Drop-In Data Center Raised Floor Grommets consist of the same qualities as the Surface Mount one. The only main difference is the design.

How does it seal air in?

  • By increasing the existing cooling unit capacity
  • Limiting the need to buy additional cooling units
  • Enhancing equipment reliability and elongating its life
  • Boosting static pressure beneath the raised floor and promoting cool air delivery through punctured tiles and floor grates
  • Supports Cold Aisle/Hot Aisle best practices

Some examples of Integral Mount Drop-In Grommets:

Koldlok Wave Grommet

  • Wave shaped thermoplastic elastomer offers the best sealing against bypass airflow
  • Overall Size: 11 x 9 x 1.875in.
  • Usable cable opening size: 7 3/4″ x 5 7/8″

Koldlok 1010 New Floor Integral Grommet

  • Overall size: 11″ x 8 1/4″ x 1 5/8″
  • Grommet usable cable opening size: 8″ x 4″
  • Grommet total cable opening size: 8″ x 5″

 

Extended Edge Data Center Raised Floor Brush Grommets

Unlike the previously mentioned grommets, these ones are designed to tackle larger openings. Plus, they include the modification of being able to address more customized openings.

How do these grommets work?

  • Help with increased cabinet density
  • Boosts existing cooling unit capacity
  • Limits the need to buy more cooling units
  • Increases the reliability in IT equipment and elongates the life of the equipment
  • Advances static pressure beneath the raised floor and betters the cool air delivery through punctured tiles and floor grates
  • Supports Cold Aisle/Hot Aisle best practices
  • Practices compliance for all raised floor cooling configurations

Koldlok Round Raised Floor Brush Grommets

Of all the grommet options, the most premium one is this one. One of its hallmarks is a revolutionary sealing technology that limits bypass airflow, boosts usable cooling unit capacity, and optimizes efficiency.

  • Upgrades existing cooling unit capacity
  • Limits the need to buy more cooling units
  • Boosts IT equipment reliability and elongates the life of the equipment
  • Improves static pressure beneath the raised floor
  • Boosts volume of conditioned air delivery through punctured tiles and floor grates
  • Practices best compliance tactics for all raised floor cooling configurations
  • The easy-to-install system reduces time and labor and requires no downtime. Round grommets allow for hole saw installation which cuts down the time by more than 50%
  • Durable ABS frame and Hybrid Brush sealing surface can be used for years
  • Hybrid Brush Technology (HBT)
