DATA CENTER & TELECOMMUNICATION APPLICATIONS

PolyPro-6

The Gund Company understands the importance of airflow management in a data center. While proper airflow is essential for equipment functionality, it is also one of the easiest ways to reduce energy costs associated with running a data center.

PolyPro FR’s material composition makes it an excellent choice for airflow management applications such as blanking panels and air baffles. PolyPro FR can also be used for cable tray liners and holders, preventing cables from tangling or snagging in a cable tray.

Cable Tray Liners

  • Easy to install
  • Reduces cable snagging, prevents cable tangling
  • Blocks unsightly views or cables
PolyPro Blanking Panel from The Gund Company

Blanking Panels

  • Prevents cool air from escaping empty rack space
  • Reduces energy costs associated with cool air generation
  • Custom sizes to meet any rack
PolyPro Air Baffles From The Gund Company

Air Baffles

  • Directs airflow and prevents seepage into unmanaged airflow areas
  • Reduces costs associated with thermal management
  • Formable to any shape to match any design layout
