Page 12: Engineering Data
Marley Sigma 1000/1200 Cooling towers are usually selected to produce a specific cold water temperature at the higher summer-time wet-bulb temperatures. During the remainder of the year, the cooling tower is capable of producing much colder water. Unless your system will benefit from the coldest possible water tempera- ture, you should consider controlling cold water temperatures to higher levels. -
Page 13: Environmental
Marley Sigma 1000/1200 Enclosures Occasionally, cooling towers are located inside architectural enclosures for aesthetic reasons. Although Sigma towers adapt well to enclosures, a poorly designed enclosure can impair proper operation. An effective design includes gener- ous air inlet paths, with the tower’s fan cylinder discharge at or above the top of the enclosure. -
