The Challenge

  • Limited space available for new air handling unit.

  • Eliminate freeze stat trips in cold weather environment and maintain 25% minimum OA air flow requirements.

  • Provide sufficient mixing without increasing length of AHU.

  • Traditional mixing technologies would have increased tunnel length by over 60″.

The Solution

  • Channel Blender installed in mixing section of custom AHU.

  • SA Flow: 47,000 CFM

  • Min. OA Flow: 11,750 CFM

  • Mixing Box Dimensions: 103″H x 152″W x 60″D

  • CB Dimensions: 93″H x 136″W x 50″D

  • OA Design Temp: -20°F

  • Minimum Temp downstream of CB: 48°F
