Dual Unit Plenum

Perfect when the application calls for redundancy in limited space

Thanks to constant technological advancements, heat loads are rapidly increasing while their enclosure sizes remain the same. Often this leads to reduced wall space which, when combined with the increased capacity requirements, restricts the available space for an HVAC system.

Fortunately, we offer dual unit plenums for our InPac and AirPak lines that retain the wall space necessary for a single unit while providing complete 100% redundancy. Plenums are available for all system sizes and in all cabinet materials including:

  • Hot-dipped galvanized steel
  • 304 stainless steel
  • 316 stainless steel
  • Aluminum

Through-the-wall style plenums are often ordered for remote instrumentation enclosures (RIEs) and motor control centers (MCCs) where redundancy is required to ensure processes are not shut down due to excessive heat in the building.

InPac Option

Dual system plenums for InPac systems require only a single wall opening

We offer several varieties of DualPac plenums for our InPac product line. For through the wall systems, the return grill opens to allow access to the interior control panels on each system. Pad mounted plenums have an exterior door that serves the same purpose. Each allows for walk-in, and InPac dual unit plenums can even be equipped with GFCI rated outlets and interior lights for maintenance.

AirPak Option

To-the-wall plenums for dual AirPak systems require minimal wall cutouts

The design of the AirPak systems lends itself perfectly to a V-bank configuration that still allows full access for maintenance of

  • Return air filters
  • Motors
  • Heaters
  • Most other major components
