The current Poster Puzzler image shows the top of Building 560, where a new supply air handler was recently installed by Facilities Maintenance and Engineering (FME) staff, as part of lab renovations in wing 1, floor 1. FME staff enlarged the attic of the building to make space for the air handler. Building 560, the largest building at the NCI at Frederick campus, houses about 120 labs and has 19 air handlers.
A supply air handler draws in outside air, filters it, cools or heats it, and adjusts the humidity to provide clean conditioned air to the laboratories. The Building 560 air handler weighs approximately 22,500 pounds and moves 22,000 cubic feet of air per minute.
