Engineered for use in most industries, Toftejorg rotary spray heads from Alfa Laval are highly efficient tank-cleaning offer exceptional cleanability, better end-product quality, greater overall output and reduced operating costs.

Cost-effective cleaning

Toftejorg rotary spray heads provide high cleaning efficiency at significantly reduced cycle times to meet the tank-cleaning requirements of various process industries – from the pulp and paper and chemical processing industries to the bioethanol and starch industries. Toftejorg rotary spray heads also provide measurable savings by cutting energy, chemicals and water consumption for virtually any tank size and configuration.

To achieve the best cleaning results, Toftejorg rotary spray heads use an optimized spray pattern to ensure efficient distribution of rinse water to all inner tank surfaces. The high-impact dense spray pattern removes any residue after the production cycle more quickly and effectively than the much more expensive and time-consuming cleaning methods of soaking in chemicals or manual cleaning. Self-draining and self-cleaning, inside and out, all Toftejorg rotary spray head devices comply with Good Manufacturing Practice.

Performance reliability and long service life

Designed for minimal internal pressure loss, Toftejorg Rotary Spray Heads rotate at pressures of less than 0.1 bar; however, the recommended operating pressure is between 2 and 3 bar. For over half a century, rotary spray head technology has proven successful in providing reliable and repeatable cleaning performance and long service life.

Alfa Laval Rotary spray head

Cleans with a rotating fan generating impact and coverage. This results in lower liquid consumption and in shorter time.

Total peace of mind with complete documentation for validation

All equipment and components in the Alfa Laval BioPharm portfolio can be supplied with Alfa Laval Q-doc, a comprehensive documentation package that provides full transparency of sourcing, production and supply chains as well as full traceability of all changes in material, manufacturing procedures or spare parts. This smoothes process validation by providing factual support to substantiate GDP (Good Documentation Practice) for every aspect of BioPharm equipment supply and provides customers with high-quality Alfa Laval products backed by a no-risk guarantee.

The Q-doc package comprises equipment manuals, product/performance test, quality and manufacturing procedures, relevant material certificates, traceability documentation, and the necessary parts and service information. This attention to detail maximizes uptime and minimizes risk.

How it works

High-impact, low-resource cleaning

Toftejorg rotary spray heads use the cleaning fluid itself to provide coverage and impact. The physical flow of the cleaning media causes the rotary spray head to rotate, with fan jets laying out a swirling pattern across the inner surface of the vessel.

These jets provide a combination of physical impact and a variable falling film of cleaning fluid that covers all the internal surfaces of the tank or reactor. The variable falling film has higher heat and mass transfer coefficients than the falling film produced by the static spray ball.

The spray head also cleans itself by directing the cleaning media through the rotating bearing track and onto the neck of the elongated head.

Rotary spray heads are a cost-effective alternative to traditional static spray balls because they use only small volumes of cleaning fluid at low pressure.

These devices are suitable for virtually all kinds of industrial cleaning, including tanks, reactors, vessels and other containers.
