Once you‘vedetermined which nozzle type is best for your application, pleaserefer to other sections of this catalog for performance data.(Informational notes will direct you to the appropriate section for the spray set-up or spray tip of interest.)To optimize the performance of automatic spray nozzles, consideradding a spray controller. AutoJet ® Technologies, the turnkeysystems division of Spraying Systems Co., provides spray controlsolutions and turnkey spray systems. See Optimization Tips on the following page for more information on how integrated spraycontrol can enhance the operation of these products.

Models include our JAU, JJAU,10530 and Variable Spray Series.– Electrically-actuated air atomizing nozzles utilize an internal 24VDC solenoid coil to directly drive a carbide ball tipped shut-offstem. Cycle speeds as high as 10,000 cycles per minute can beachieved. No compressed air is required. Models include ourPulsaJet ® 10000, AA28 and AA29 Series. ã Hydraulic automatic spray nozzles can also be air- or lctrically-actuatd. – Air-actuated hydraulic nozzles use nozzle orifice geometry to precisely disperse and meter a pressurized liquid. Optionsinclude AA24AUH, JAUH and JJAUH Series.– Electrically-actuated hydraulic nozzles use an internal 24VDC solenoid coil. Models include our PulsaJet 10000 andAA26AUH Series.Additional information can be found in Section F, Air AtomizingSpray Nozzles and Sections B, C and D where UniJet spraynozzles are featured.

Fromsimple timing control to complex closed-loop control, patented technology enables these controllers to optimize the performanceof your spray nozzles or manifolds.How AutoJet Spray Controllers can improve your sprayoperations: How Pulse Width Modulation (PWM) works: Note: PWM is not appropriate for all applications. Consult your localsales engineer. Pulse width modulated flow control involves switching anautomatic spray nozzle on and off repeatedly at a controlledrate. PWM provides distinct advantages for some sprayapplications. ã Easily and very precisely control flow rate without adjusting spray pressure or affecting spray integrity. ã Reduce misting by producing a larger drop size than typical for a given flow and pressure. ã Decrease nozzle clogging by using a larger nozzle orifice while limiting flow rate. ã Provide an extremely high flow turndown ratio that can be achieved at a single pressure (up to 10:1 or more dependingon the regulating frequency and spray gun used).AutoJet Spray Controllers can also utilize a signal from apressure transducer to automatically compensate for variablesupply pressures by adjusting the duty cycle to maintain aconstant flow rate.AutoJet Spray Controllers from AutoJet Technologies accuratelymonitor and control spray applications for increased productionefficiency.Self-contained AutoJet Modular Spray Systems provide aconvenient way to automate your spray applications. Fullyintegrated electrical and pneumatic control panels enhance theperformance of automatic spray nozzles.See Introductory Section or visit www.autojet.com for moreinformation on AutoJet Technologies.Applications ideally suited for spray control: ã Batch spray controlã Coatingã Conveyor sprayingã Even cooling of web- and sheet-based productsã Gas cooling and conditioningã Lubricatingã Markingã Tank cleaningã Fine-tune timing of automatic spray nozzles to accurately sprayã Establish automatic clean-out cycles to minimize nozzle plugging.ã Easily program system set point parameters.ã Use Pulse Width Modulation (PWM) to vary the flow rate of electric spray nozzles at a fixed pressure. ã Improve troubleshooting of spray performance.ã Notify operators or shut down on specified faults.ã Integrate control of your spray application with existing plant control systems. Automatic Spray Nozzles moving targets and prevent dripping on nozzle actuationor shut-off. ã Maximize cycle speed of automatic spray nozzles.ã Precisely control liquid pressure, atomizing air pressure and fan air pressure to ensure proper flow rate, spray angle anddrop size.
