Spray Nozzle Distributor

As the name indicates, this style distributor consists of spray nozzles arranged on pipe assembly. It is generally used for shallow beds in heat transfer applications, in scrubbing services, and applications where a large vapor handling capacity is most important. It can also handle low liquid flow rates.
The quality of distribution is somewhat inferior compared to orifice type distributors because the spray cones create areas of uneven irrigation and a significant amount of liquid is directed towards the tower wall. The main header is flanged at one end and clamped to a column wall clip at the opposite end. Depending on the column diameter, the individual laterals may also be clamped to column wall clips.

Selection criteria*:
• Column diameter >250 mm (10 inches)
• Maximum Turn-down ratio 3:1
• Liquid rates: 0.5-120 m³/m²hr (0.2-50 GPM/ft²)
• Clean service

*Selection criteria guidelines provided are typical but not limiting. Under certain conditions, special design provisions can be made for accommodating varied hydraulic and mechanical requirements.
