Cell Partition Options
Every Sigma tower includes plenum chamber partitions and hot water distribution basin partitions between adjacent cells. Plenum partitions ensure consistent thermal performance as you shut off one fan at a time. They keep air from entering an operating cell through an adjacent idle fan, maintaining efficient thermal performance. Basin partitions let you inspect and clean individual basins while the rest of the tower continues to operate.
Specify extra partitions carefully because excess partitions can sometimes discourage routine maintenance and good housekeeping procedures. Two options are available to meet specific design goals:
•Fill area partitions are available, but usually not necessary. The solid sheet design of film fill prevents water and air migration between the fill areas of adjacent cells, regardless of operating mode.
•Complete watertight partitions provide total cell isolation. These partitions let you use adjacent cells to serve separate loads with incompatible system temperatures. Watertight partitions extend from louver- face to
Optional weir gates in wood basin partitions let you mix or segregate the water in the basin to meet your operating needs. Marley weir gates come with removable cover plates.
