Local and Global Suppliers of Atomising Spray Nozzles

Spraying Systems Ltd is the gateway for customers in the UK and Ireland to access the products and global resources of its parent company Spraying Systems Co., the world leader in spray technology.

Local resources offered by Spraying Systems Ltd from its UK and Ireland headquarters at Farnham in Surrey include:

• Advice on nozzle selection, system planning, maintenance.
• On-site consultation with regionally-based qualified engineers.
• Point of contact for AutoJet Technologies® – international division for development and supply of complete automated systems and turnkey projects.
• Equipment demonstrations and trials by arrangement, at SSL or at customer sites.

Spraying Systems began the design and manufacture of six types of nozzle in a converted Chicago garage in 1937. From the beginning it was decided to concentrate entirely on spray technology, and the company has specialised in it ever since. Today the company designs and manufactures many thousands of different spray products, operates production plants in four continents and offers sales and technical support through more than 80 offices worldwide.

Spray Nozzles

Whatever Spray Nozzle you are after, we will have the solutions for you. We have thousands readily available in dozens of materials with hundreds of configurations. Our Nozzles are designed to improve efficiency, they are innovative and excellent quality.

The product range extends into tens of thousands and gives full coverage of more markets than is realistically claimed by any other Spray Nozzle manufacturer. The main Spraying Systems industrial spray catalogue is published in 12 languages, reflecting the global reputation of Spraying Systems as experts in spray technology. Topics covered in Catalogue 70M (the metric edition) include:

• Nozzle application guide
• Basic nozzle types, characteristics
• Performance factors
• Calculations and formulae
• System optimisation
• Nozzle maintenance advice
• Technical data on nozzles and accessories

In multi-page sections the technical data pages give performance and other details for full-cone, flat, hollow-cone, fine, air-atomising and automatic spray nozzles, spray guns, tank wash products and spray accessories. There is also a section for special purpose nozzles, identifying the nozzles and other spray products most commonly applicable to the special problems encountered in such sectors as automotive, chemical processing, cement manufacture, car wash, pressure washing, electric power, electronics industry, fire protection, food processing, metal pre-treatment, papermaking, pharmaceuticals, pollution control and steelmaking.

Spraying Systems is much more than a producer. It offers in-house facilities dedicated to spray analysis and research, the design and fabrication of spray lances, manifolds and other assemblies and, not least, the design, building and commissioning of complete automated spray systems under turnkey contracts.

Automated Spraying

In the last decade, Spraying Systems has led developments in this increasingly important area.

A spray nozzle can only perform to its potential if the entire spray system operates efficiently. All system components - spray nozzles, pumps, sensors and other hydraulic and pneumatic components - must be accurately controlled. AutoJet Technologies, with a European technical centre at Gent in Belgium, was created for this purpose, engineering entire systems that optimise spray performance, enabling customers to improve product quality and reduce production costs.

Developing its own range of spray controllers and dedicated SprayLogic™ software, AutoJet Technologies works closely with other Spraying Systems laboratories and technical resource centres in the US and elsewhere. And being also able to draw on the world’s widest range of nozzles and special spray products, AutoJet Technologies has designed and built innovative spray systems across a broad spectrum of industry.

Customers include food processors, bakeries, a door manufacturer, paper tissue mills and producers of OSB (engineered wood) panels. Applications range from food coating to fault marking on a high-speed paper machine.

A typical field of application is gas conditioning. The AutoJet Gas Conditioning System is designed around Spraying Systems’ FloMax air-atomising nozzle and controlled by an AutoJet spray controller pre-programmed for gas cooling and conditioning applications.

The controller manages the closed loop system by regulating liquid and air flow to the FloMax nozzles based on information provided by one or more temperature sensors. FloMax air atomizing nozzles deliver optimal drop size without creating excess moisture. They offer the greatest energy efficiency available and maximum flexibility, with high flow-rate turndown ratio.

Many Spraying Systems developments arise directly from the company’s close involvement with the industries it serves – leading to better understanding of customer needs and how they might be met. This in turn has led to further innovation. In the confectionery industry, for example, collaboration between company and confectioners was given practical impetus in 2009 by the opening of a new Spraying Systems facility dedicated to the development of heated spray systems for spraying chocolate and other temperature-sensitive products..

In AccuCoat® Heated Spray Systems, liquid temperature is automatically monitored and controlled from start to finish by means of an AutoJet® spray controller. All components carrying the liquid, including pressure tank, valves, flexible pipes and manifold are heat-jacketed. These systems can be configured for applications ranging from pan coating to conveyor based operations. Benefits include more even coating, reduced material waste, higher productivity and more consistent, repeatable results

Spray expertise still begins with the nozzle and Spraying Systems remains at the forefront of nozzle design. One of the company’s many innovative developments is its patented PulsaJet® nozzle range.

The PulsaJet nozzle is an electrically controlled nozzle that can be switched on and off at rates of up to 10,000 cycles/minute. Teamed with an AutoJet spray controller it works automatically, controlling flow by means of pulse width modulation. On a conveyor installation it can cut in and out instantly on signal so that it only sprays when the target is below. Moreover it can be programmed to vary flow continuously in response to variations in line speed or, for example, fluctuating signals from a weighing hopper. A major advantage in coating operations is that flow rate can be controlled precisely down to very low flows with no change in liquid pressure, spray width or droplet size.

Given the diversity of Spraying Systems’ nozzle range and applications, its strength and expertise in certain specialised areas such as tank cleaning have surprised some customers. But its experience in this field goes deep and its range of tank cleaning products is one of the most comprehensive available. The company offers automatic tankwash devices ranging from fixed spray balls for low pressure rinsing of small vessels to motorised or fluid-driven tankwashers for high-impact cleaning of tanks up to 20m or 30m diameter.
