MARQUETTE UNIVERSITY PHYSICIAN ASSISTANT STUDIES BUILDING

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
