In addition to Sterling’s superior spray valve, our tray type deaerators are also equipped with the Sterling Tray Assembly. The Sterling Tray Assembly is constructed of 16 gauge, type 430 stainless steel and is fastened in one of two ways, with stainless steel rivets or study interlocking stainless steel clips. Each tray assembly consists of two staggered rows of four tray channels.

This staggered tray channel pattern ensures maximum feedwater retention and reduced pressure drop which results in optimum heating surface and deaeration.
