consider our automated AutoJet®
Gas Conditioning System
Maximize the performance of FloMax® nozzles
and enjoy the benefits of automation by using the
AutoJet Gas Conditioning System. The system uses the
AutoJet Spray Controller, with SprayLogic® firmware and
software, to monitor operating conditions and automatically
adjust system components as needed. By regulating liquid
and air flow to the nozzles based on data gathered from
temperature sensors, the controller ensures the highest
level of reactivity and accuracy for the system.
All system components – nozzles, pumps, sensors and other hydraulic and pneumatic devices – are controlled by the AutoJet Spray Controller. If a problem is detected the controller can't resolve automatically, operator warnings will be displayed or sounded.
Other key features include:
• Multiple lance zones can be configured to allow
greater turndown of flow rate under variable system conditions.
• Variable Frequency Drive (VFD) pumps provide proportional liquid regulation and significant electricity savings.
• Energy-efficient proportional air regulation reduces air consumption and operating costs.
• The AutoJet Spray Controller is easy to use and equipped with complete spray "knowledge" for easy configuration.
• Operates independently or can be integrated with other plant control systems.

1.800.95.SPRAY Intl. 1.630.665.5000 www.spray.com FloMax® A Series: Produces Smaller Drops, Uses Less Air. Here's How:
When it comes to drop size, the goal is to minimize Dmax and achieve a finely atomized spray with D32 less than 100 microns at 10 gpm (37.8 l/min). This drop size cannot be achieved with a single-step atomization process. A multi-stage process is required. FloMax nozzles use a patented three-stage atomization principle to produce a highly focused air stream that shears the liquid with minimal air. The result is a D32 drop size 34% smaller using 20% less air than competitive nozzles (flow rate of 10 gpm [37.8 l/min]). Each nozzle uses as little as 45 scfm (76 Nm3/hr). Energy costs are lowered and compressor life extended. The very small drops produced by FloMax A Series nozzles reduce dwell time required for complete evaporation and reduce the risk of wetting. Plus, the liquid being sprayed generates more surface area per gallon (liter). The uniformity of drop size distribution produced by FloMax A Series nozzles ensures precise, tight control of drop size. This is another unique attribute – FloMax nozzles provide a narrower Relative Span Factor (RSF) than many other air atomizing nozzles at most air pressures. FloMax A Series: principle of operation
1 Stage One: Primary Fluid Breakup
Air and liquid converge at the annulus allowing high velocity air to shear the liquid column.
2 Stage Two: Secondary Fluid Breakup
Focused stream impacts the target bolt forcing additional mechanical breakup.
3 Stage Three: Final Mixing
Air cap acts as a final mixing chamber. As liquid crosses multiple orifices, an additional pressure drop provides the final atomization. 1.800.95.SPRAY Intl. 1.630.665.5000 www.spray.com FloMax® Anti-Bearding Nozzles
FloMax Anti-Bearding nozzles provide all the benefits of FloMax A nozzles but feature a patented air cap design to resist material build-up near nozzle orifices and prevent performance problems. FloMax Anti-Bearding nozzles can last up to five times longer before maintenance is required to remove build-up making them ideal for use in slurry and high-particulate spraying applications.
A bit about bearding:
In many air atomizing applications, a low-pressure zone is
created by the high-velocity fluid stream exiting from the nozzle
orifices. This zone draws a few fine droplets back to the air
cap. The droplets dry, build up in layers and often block liquid
and air orifices. This phenomenon is called bearding and is a
leading cause of distorted spray distribution and clogging.
The areas where low-pressure zones are typically created in air atomizing nozzles – the center of the air cap and between orifices – have been minimized on the FloMax Anti-Bearding nozzle.
FloMax Anti-Bearding Series feature 10 orifices at compound
angles. These orifices produce a very full spray when leaving the air cap. The spray pulls in as it travels and provides a 55° spray angle.
Five Additional Benefits FloMax A and FloMax Anti-Bearding Series Offer
Fewer nozzles required for cooling.
Use lower quality water sources.
FloMax nozzles offer a large flow rate per nozzle. Competitive FloMax nozzles feature large free passages. This means the nozzles with equivalent flow rates produce larger drops. risk of clogging is reduced and lower cost water supplies Fewer FloMax nozzles can be used, resulting in lower initial such as river water, basins and run-off water can be used costs and less maintenance time on an on-going basis. with confidence. Maximum flexibility because of high turndown ratios.
Reduced maintenance time.
High turndown of flow rate – up to 10:1 – is possible. Durable, long-wearing parts require little maintenance. This allows the air pressure to be constant while the But when maintenance is required, it is fast and easy. liquid varies based on process requirements. Replacement of the nozzle or just the air cap and/or air annulus can be done without special tools. Competitive Effective even in harsh environments.
nozzles require more maintenance and more frequent A wide choice of materials ensures optimal nozzle replacement because of smaller free passages and performance even in high-temperature and corrosive the use of higher air and liquid pressures. applications. Typical materials include 316 and 310 stainless steel, Hastelloy®, Stellite® and reaction-bonded silicon carbide.

Benefits to the A Series and Outperform
All Other Small Capacity Nozzles
A new multi-stage cross-hole nozzle design provides superior atomization by shearing the liquid prior to mixing with the high velocity air stream. This unique atomization process yields small drops at lower operating pressures than other nozzles. The result is tight drop size control, lower consumption of compressed air and/or use of a smaller compressor and longer compressor life. FloMax X Series nozzles have a liquid turndown ratio of up to 10:1. This allows the air pressure to be constant while the liquid varies based on process requirements. The 10:1 turndown ratio far surpasses conventional air atomizing nozzles with ratios of 2:1 or 3:1. The wide operating range of the FloMax X Series adds significant flexibility during operation without compromising performance. The narrow 20° spray angle is ideal for applications where tight control of drop size and spray precision are critical. Multiple nozzles can be configured on a lance or in a duct or vessel to deliver targeted sprays in critical processes. FloMax X Series nozzles provide a narrower RSF than many other air atomizing nozzles at most air pressures.
A 55° spray angle is also available for applications requiring more spray coverage. FloMax X Series nozzles are suitable for demanding applications – material options include 310 and 316 stainless steel and Hastelloy®. Other materials are available upon request.

Similar to the FloMax A Series,

flow into four smaller streams. • A choice of mounting options and easy installation. 2 Stage Two: Secondary Fluid Breakup
The liquid – all four streams – is sheared by air as it exits the cross holes.
3 Stage Three: Final Mixing
The air cap acts as a final mixing chamber. As liquid exits the orifice, an additional pressure drop provides the final atomization. 1.800.95.SPRAY Intl. 1.630.665.5000 www.spray.com Lance and Injector Solutions
Ranging from Simple to Complex
FloMax® nozzles are designed to yield very precise performance. Equally important in a spray system is the spray injector (also known as a spray lance) that delivers the liquid and/or gas to the spray nozzle. Spray injectors must also meet exacting standards to ensure optimal performance.
We offer a full range of spray injectors:
• Our standard lightweight FloMax injectors are readily available in 0°, 45°
and 90° configurations with quick-release or bolt-on flanges and optional adapters, cooling jackets, purge tubes and protective tubes. • When non-standard solutions are needed to meet challenging physical 0° Lance Assembly
