Clog‐Resistant Maximum Free Passage FullJet® Nozzles Now Available in Larger Sizes

Spraying Systems Co. has expanded the MFP (Maximum Free Passage) FullJet full cone nozzle line to include 1‐1/2″, 2″, 2‐1/2″ and 3″ sizes for applications with flow rates up to 705 gpm (2670 lpm) and 80 psi (6 bar). The MFP FullJet line now includes nozzles ranging from 3/8″ to 3″ sizes. All are available in 316 stainless steel and sizes up to 1‐1/4″ are also available with brass bodies.

MFP FullJet nozzles feature a unique vane design and the largest free passage of any conventional full cone nozzle. They are ideal for any application which is affected by clogging problems due to recirculated liquids or debris, including washdown, process and gas cooling, flue gas desulfurization, food processing, dust suppression, fire protection, foam control and waste water aeration.

The ability to allow passage of larger particles reduces clogging and provides increased production time and longer service intervals without maintenance. Product loss or scrap caused by distorted spray patterns due to blocked flow passages is also decreased. MFP FullJet nozzles allow free passage of particles 30 to 75% larger than those allowed by standard full cone nozzles.

MFP FullJet nozzles also produce a more uniform, true full cone spray pattern than other large free passage nozzles. Other large free passage full cone nozzles produce a pattern more similar to a hollow cone spray pattern with heavy edges and light centers. The MFP FullJet full cone spray pattern provides more effective, consistent coverage and ensures product and process quality.

The Value of Spray System Optimization

Pretreatment systems are too often perceived as being pretty simple. A few pipes, a pump, some liquid and a few spray nozzles. What could be simpler? As long as the pump is working and the nozzles are spraying everything’s fine, right? In many cases, the reality of what your system is actually producing couldn’t be farther from that statement. When it comes to your system’s spraying performance, if you don’t have a comprehensive Spray System Optimization Plan in place, it may be costing your company thousands of dollars per year…

Spray nozzles are a precision component of your pretreatment system, designed to produce a specific performance under very specific conditions. Just because a nozzle is spraying doesn’t mean that it’s working properly. As you’ll see, many factors can reduce the efficiency of a spray nozzle and ultimately your entire system.
To achieve long-term, optimal performance, you need to examine your entire spray system and develop a plan to evaluate, monitor and maintain it on a regular basis. If you don’t have a Spray System Optimization Plan in place already, now is a good time to establish one.

This 52-page handbook, “Optimizing Your Spray System,” is designed to help spray system users assess the effectiveness of their current spray systems, solve spray problems and optimize system performance.

Five Easy Ways to Cut Costs in Drying and Blow-Off Operations

Compressed air is costly. Yet, it’s often viewed as a fixed utility cost and overlooked when making process improvements. That’s a mistake – making changes in drying and blow-off applications can save hundreds of thousands of dollars annually.

#1: Eliminate compressed air by using blower-powered air knife packages

Air knife packages that use rugged, reliable regenerative blowers can result in tremendous energy savings. One plant saved more than $500,000 annually by replacing air nozzles with an air knife package. Another plant saved $162,000 annually.
An air knife/blower package may produce similar results for your operation if:

velocity rather than impact is required
the oil in compressed air is causing quality problems
the application area is 2′ or larger
heated air is needed

Regenerative blowers are rugged, reliable and require infrequent, minimal maintenance. Learn more.

#2: Reduce compressed air use up to 92% with low flow air knives

If you are using open pipe, you can experience big savings by changing to low flow air knives that produce a uniform, high-velocity air flow across the entire length of the knife. The result is fast, efficient drying with minimal compressed air use. Use in small areas where the knives can be positioned close to the target and in processes that can’t tolerate increases in temperature. Learn more.

#3: Spot drying? Blow-off? Air amplifiers can reduce air use up to 90%

Air amplifiers produce a constant, high-velocity air stream for fast drying and blow-off applications. Efficiency is maximized because additional free air is pulled through the amplifier along with the compressed air. If you’re using open pipe, you can reduce air use up to 90%. If you’re using compressed air nozzles, you can use up to 60% less air. Learn more.

#4: Reduce costs and noise by replacing open pipes with compressed air nozzles

Open pipes and pipes with slits are easy to manufacture and inexpensive but are wasteful and noisy. Changing to air nozzles that convert low-pressure compressed air into a targeted, high-velocity air stream, a flat fan or a curtain of high-impact air reduce compressed use by 25% to 35% and lower perceived noise up to 60%. Air nozzles are ideal for drying and blow-off. Learn more.

#5: Take Advantage of Our FREE Drying and Blow-Off Operations Audit

One of our local sales engineers will conduct an on-site audit of all your drying and blow-off operations. The audit includes:

An estimate of how much compressed air is being used
Recommendations on how to reduce compressed air use
An estimate of how much you’ll save

There is no charge for this service. It is just a fast and easy way to have an expert evaluate your drying and blow-off operations.

Optimizing Injector Performance in Water Wash, Chemical Injection, Gas Treatment and More

Incomplete chemical reactions, wall wetting, corrosion, damage to downstream equipment, excessive maintenance, premature failure and outages are just some of the costly problems that can result from quills or injectors that are not optimized for specific operating conditions. These problems are fairly common. However, they can be prevented with proper planning, design and fabrication. Here are a few key factors to consider before you specify an injector or quill.

Spray performance. If you think a quill will deliver the performance you need, think again. A slot in a pipe doesn’t provide the same precise flow and drop size control as an injector with a nozzle.
Spray direction – co-current or counter-current. This decision has a significant impact on nozzle selection and injector placement in the gas stream. It can also affect maintenance requirements and injector service life.
Materials of construction. Thermal stresses, vortex shedding, heat transfer and many other operating conditions need to be evaluated carefully to prevent injector failure.
Performance validation. Validating performance before injector design is finalized is essential. Computational Fluid Dynamics (CFD) modeling can simulate your exact operating conditions and validate injector design, placement in the gas stream and materials of construction before manufacturing begins.

Water Use: Make Small Changes, Achieve Big Savings

Changing the way you spray can yield big savings in water, chemical, wastewater disposal costs and energy. If you use water in your cleaning, sanitizing, cooling or coating operations, it is likely you can save tens of thousands or hundreds of thousands of dollars by making simple changes. See the water-saving strategies below. You may be able to get results like these:

A chemical processor automated tote cleaning and is saving 4 million gallons of water per year
A dairy reduced water use by 13 million gallons annually by changing spray nozzles, adding shut-off valves and fixing leaks

Number 1:

Check for nozzle wear. Worn nozzles spray over capacity, wasting water and chemicals.
Just because a nozzle is spraying doesn’t mean that it is working optimally. The size of the nozzle orifice will increase as the nozzles wear. Depending on the number and type of spray operations, the cost of replacement nozzles can be far less than the cost of wasted water, even if the nozzles are only 15 to 20% worn. Monitor flow meter readings to detect increases. Learn more.

Number 2

Use self-cleaning nozzles or strainers especially with recycled water
Solid particles in water can damage nozzle orifices and/or increase wear. Using self-cleaning nozzles, nozzles with integral strainers and line strainers are an effective way to protect nozzles from damaging debris. There are many options available suitable for use in nearly every operation. Learn more.

Number 3

Use spray guns instead of open hoses
Water consumption can be reduced by half or more using spray guns instead of open hoses. Ensuring water is “on” only when needed makes a big difference. Use spray guns for general plant clean-up, equipment sanitation and more. Learn more.

Number 4

Automate tank cleaning
Manual tank cleaning and fill/drain methods can easily waste hundred of gallons of water each time the tank is cleaned. A change to automated cleaning will dramatically reduce water and chemical use and tanks will be cleaned more thoroughly in less time. Dozens of tank cleaners and tank cleaning nozzles are available for use with tanks up to 100′ in diameter. Learn more.

Number 5

Fix leaks
A simple, but often overlooked, solution is fixing leaks. Some plants have reported a 14% reduction in water consumption just by fixing leaks. Sub-meters can be installed to detect leaks. Learn more.

Six Strategies to Reduce Water Consumption – Strategy 6

Tanks, vats and vessels are often cleaned manually using hoses or by filling and draining the tank multiple times. Depending on the tank size, these methods can use hundreds of gallons of water every time the tank is cleaned.

Some manufacturers save as much as $50,000 per year per tank by switching to automated cleaning. Clean-in-place (CIP) systems use spray nozzles to provide controlled, thorough cleaning and rinsing. High impact motorized tank washers and automated turnkey systems are other options.

Motorized & fluid-driven Tank washers provide high-impact cleaning & reduce water / chemical use & labour cost.

In addition to save water, automated tank cleaning offers other benefits, including: faster, more thorough cleaning; reduced use of chemicals; reduced disposal costs; improved worker safety; reduced labor costs and maintenance downtime.

Turnkey systems integrate pumps, sensors, motors and valves designed to optimize the performance of tank cleaning nozzles. Systems can be equipped to re-circulate cleaning liquid in a closed loop, allowing the re-use of a portion or all water and chemical cleaning solutions.

Optimize spraying.

Spray nozzles are precision component designed to yield specific performance under specific conditions. Just because a nozzle is spraying doesn’t mean that it is working optimally. An out-of-specification spray system not only depletes a valuable resource but also can lead to other problems such as quality control issues, unscheduled production downtime, increased maintenance and increased consumption of chemicals and electricity. The cost of these problems can be surprising and, in some cases, staggering. To ensure that a spray system is operating at peak efficiency, begin with an audit of the system by a reputable nozzle manufacturer. An audit is typically offered at no cost and takes up to four hours. It includes an inspection of all nozzles on the paper machine, identification of nozzles that need replacement and written report with optimization tips.

Six Strategies to Reduce Water Consumption – Strategy 4 and 5

In many applications, orifice deterioration and clogging are caused by solid dirt particles in the sprayed liquid. This is particularly common in systems using continuous spray water recirculation. In an average production process, recycling of water enables about 17 uses before discharge, as apposed to one or two uses without recirculation.

Self-cleaning nozzles feature a piston-type design. When line pressure is low, the piston retracts to purge debris from the nozzle orifice. Self-Cleaning nozzles are ideal for use in showers with high-solids content in the water and also inside paper machines because of the compact design.

Strainers, or nozzles with built-in strainers, trap larger particles and prevent debris from entering the nozzle orifice or vane to significantly reduce wear. A spiraling motion sweeps suction scanner nozzles across the screen to remove debris in self-cleaning strainers.

Six Strategies to Reduce Water Consumption – Strategy 2 and 3

Nozzles made from harder materials generally provide longer wear life. Standard materials are brass and stainless steel but more durable spray nozzles are available in speciality materials like HASTELLOY®, in various carbides or with ruby orifices.
A synthetic ruby orifice is frequently used for web trimming because it provides superior spray precision for a sharp, crisp edge and up to 2000 times greater wear resistance than brass. In addition, the stream remains steady even in the early stages of wear.

Worn nozzles are a common problem in the manufacture of Pulp & Paper. Determine the optimal maintenance schedule based on the specifics of your opperations.
Replace worn nozzles regularly. The cost of replacing nozzles is a lot less than the costs of wasted water or chemicals.

A comprehensive nozzle maintenance program will help ensure trouble-free performance of your spray system as long as it is performed properly and routinely. Since this is a critical step in spray system optimization, we offer nozzle maintenance workshops and nozzle audits as a service to our customers. Workshops typically include a review of the customer’s current program and recomendations for improvement, on-site inspection of spray nozzles and training of maintenance personnel.

PWM Flow Control

Pulse Width Modulation (PWM) Enables Flow Rate Control Without Changing Spray Pressure

Benefits

Flexibility: Achieve a wide range of flow rates with a single nozzle
Immediate flow adjustments: Using AutoJet spray controllers, response time of electrically-actuated PulsaJet spray nozzles is almost instantaneous
Reduced clogging: Maintain low flows even with large spray orifices for improved reliability and reduced maintenance
Reduced misting: Low flow operation using larger orifices at low pressures reduces the misting common at higher pressures and improves transfer efficiency and safety
Uniform coating/improved quality: Constant pressure operation prevents variations in spray angle and drop size for more even coating over a wide range of flow rates

PWM Food Processing

Examples of PWM Flow Control Applications in Food Processing:

Spraying flavors or oils onto bread, pastries and rice cakes
Surface coloring with egg coating, milk protein, or caramel
Moistening dough with water to maintain proper consistency
Misting bread with water to improve seed adhesion
Spraying food ingredients onto products or into trays
Spraying water on hamburger patties, vegetables and pizza prior to freezing to maintain proper weight
Spraying antimicrobial agents onto meat & poultry for food safety

Spraying aroma onto coffee and other food products

What You Need for PWM Flow Control

A fast spray nozzle
Electrically-actuated PulsaJet nozzles achieve speeds up to 10,000 cycles per minute and are ideal for PWM flow control. PulsaJet nozzles also offer accurate spray placement, excellent spray pattern integrity and a choice of hydraulic or air atomizing spray tips.

A spray controller–plus software
AutoJet Technologies offers a wide range of spray control options for manual or automated PWM flow control
regulation. Basic versions offer PulsaJet nozzle control with manual flow adjustment and advanced versions
provide total automation, optional spray detection/verification and more.

Spray knowledge
Effective PWM flow control requires a strong knowledge of how liquids flow and how spray nozzles work. Turning a spray nozzle on and off very quickly is not enough.

Six Strategies to Reduce Water Consumption – Strategy 1

At the heart of all spray operations in your mill, is the spray nozzle. It is the component that determines performance in moisturizing, cleaning, lubricating, edge trimming, bleaching, knock-off, gluing and dozens of other applications . Worn nozzles can raise water consumption drastically.

The cost of using nozzles worn by only 15% in your mill can increase by thousands of Rands.

At Spraying Systems Co we have developed 6 strategies to help you save water, chemicals and energy in your mill.

Flow

Centrifugal pumps: Monitor the readings of your flow meter to check for increases in flow.
Use a calibration vessel to measure the flow of a nozzle for a specific time at a specific pressure.
Compare the readings with the manufacturers catalogue or compare them with the same tests conducted on a new nozzle.

Positive displacement pumps: In applications using positive displacement pumps, which provide the same capacity regardless of pressure, the spraying pressure will decrease as the nozzle orifice enlarges. Lower spray velocities and spray impact will result.

Pressure at showers and nozzles

Centrifugal pumps: Monitor for increases in volumes of liquid sprayed. The pressure of the spray could decrease.

Positive displacement pumps: Monitor gauges to detect any drop in pressure and reduction on the impact on surfaces sprayed. The volume of the sprayed liquid may remain the same. Also monitor for any increases in pressure which could be caused by blocked nozzles.

Drop sizes

As nozzle orifices wear, the liquid flow increases or the spraying pressure drops, resulting in larger drop sizes. Larger drops result in less total liquid surface area.
Actual drop size

Impact

Check for premature wear of the felt or any other related problems. In applications with centrifugal-type pumps, impact may actually increase because of the increased flow through the nozzle.

Spray Pattern

Visually inspect the spray pattern to detect any changes in uniformity.
Streaks and heavier flows in the centre of the pattern, accompanied by a decrease in the effective spray angle coverage typify deterioration.
Measure the width of the spray over the surface sprayed.
If the nozzle wears gradually, you may not be able to detect any changes until a significant increase of flow is evident.

Spray patterns of both tips show little difference. Spray collection in tubes gives dramatic evidence of 15% increase in capacity.

Air Knife Drying Packages Eliminate Compressed Air Use in Drying and Blow-Off

WindJet Air Knives powered by energy-efficient regenerative blowers provide excellent performance in drying and blow-off operations and eliminate the need for costly compressed air. Operating costs can be reduced by as much as 95 percent when the packages are used in a wide range of operations including debris and dust blow-off, removal of excess water and moving products.

WindJet Air Knives feature a unique 1/8″ leading edge along the length of the knife to direct a consistent and controlled air stream that retains its integrity further downstream and eliminates spotting and blotching. The air stream produced by the knives entrains ambient air to increase the total volume of air and maximize drying and blow-off efficiency.

Unlike other blower types, the regenerative blowers included with the packages are rugged, reliable and require infrequent, minimal maintenance. Plus, no sound enclosure is needed because the blowers provide low noise operation. Each air knife package is customized for the application. Air knives are available in lengths from 6” to 36” and two air slot sizes, .040” and .060”. Regenerative blower assemblies are available from 5.5 to 30 HP. Packages include pressure relief valve, pressure gauge, air inlet filter, filter monitoring gauge, vibration dampener, fittings and mounting adapter.
