Model 943 spray nozzle distributor for severe services

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.

The weir trough distributor is specifically designed for applications with severe fouling conditions and high liquid flow rates.
  • It is well suited for applications where the liqiuid feed stream contains solid particles.
  • It is the preferred choice for the slurry pumparound zone of an FCC main fractionator.


The Model 985 distributor is fabricated in sections for installation through a vessel manway. It can be designed with various support methods, depending on specific mechanical and process requirements.

For redistribution between packed beds, a separate liquid collector is required.
