Dispenser with spray nozzle Model 943

Spray nozzle distributors are primarily used for heat transfer and refinery applications where good liquid coverage and complete wetting of the bed is necessary. In heat transfer applications, the distributors produce a liquid spray cone that enhances heat transfer by providing contact with the rising vapor before the liquid reaches the packing. In refinery fractionators, spray nozzle distributors are commonly used in scrubbers, wash zones, and pumparound zones. The Model 943 distributors can be designed for very low liquid rates because each spray nozzle covers a large area of the tower. Relatively large nozzle opening sizes provide a reasonable flow, even at low irrigation rates, and reduces the likelihood of plugging.
