CRITICAL CENTRAL AIR-HANDLING STANDBY UNIT: OWNER IN-HOUSE PROJECT MANAGEMENT

摘要

This month's B2B will focus on a large pharmaceutical building that chose to invest in a standby secondary AHU (AH-6) to be ready in parallel with five other secondary central AHUs serving a 6,000-sq-ft Class 1,000 cleanroom space. Each existing unit is 40,000 cfm, and the new standby unit will be identical in configuration and size and serve to provide standby capacity should any one of the existing five units fail during operation. It will also serve when any of the other five units is scheduled for planned maintenance.
