Air Sealing Grommets

Improve efficiency & capacity with air sealing grommets

Tate's air sealing grommets are designed to improve the energy efficiency and air sealing performance of your data centre by preventing leakage from the raised floor plenum when penetrations are required for power and data cables above the floor.

Key Preformance Characteristics

  • Increases cooling unit effectiveness
  • Allows for greater IT density in data centres 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 buy additional cooling units
