C.E. Shepherd Quick Change Orifice (QCO) Nozzles

C.E. Shepherd Quick Change Orifice QCO Nozzles are injection-molded polypropylene water distribution nozzles designed for counterflow splash-fill cooling towers. They enable quick maintenance, flexible flow control, and uniform water dispersion across heat-transfer media. Their interchangeable orifice system allows operators to adjust flow rates without replacing the complete nozzle assembly, making them suitable for retrofit and new cooling tower systems.

  • Industrial cooling towers
  • Counterflow splash-fill towers
  • Variable load facilities
  • HVAC plants
  • Water treatment systems
  • Cooling tower retrofit projects
  • New cooling tower installations
  • Flow calibration systems
  • Thermal optimization upgrades
  • Routine maintenance applications

 

These features support fast maintenance, flexible flow control, and reliable counterflow tower water distribution.

  • An interchangeable orifice allows quick flow changes.
  • Modular design supports system adjustments.
  • A diffusion plate improves water spread.
  • A large opening helps reduce clogging.
  • Polypropylene body resists cooling tower conditions.
  • 1.5″ MPT connection fits standard piping.
  • Works with saddle adapters.
  • Supports nozzle extension installation.
  • Suitable for retrofit projects.
  • Easy maintenance reduces tower downtime.

These specifications define the QCO nozzle’s material, connection type, temperature limits, and system compatibility.
