General description
The Alfa Laval Toftejorg Rotary Spray Heads are tank cleaning machines intended for industrial use in tanks, vessels and
containers under typical CIP procedures. They have a broad range of application areas within pharmaceutical, food and
chemical industries.
The Alfa Laval Toftejorg Rotary Spray Head is a sanitary cleaning device of the rotating fan spray type for permanent installation
that provides a cleaning pattern from 180° - 360°. The machine is completely self-cleaning and when properly installed
also self-draining (see page 12). All product contact surfaces are AISI 316L stainless steel (or better corrosion vice) or FDA
compliant and EU 10/2011 compliant polymer materials.
All assemblies are fully welded. The cleaning device is lubricated by the cleaning media. No oil, grease or other lubricants
are used.
The Alfa Laval Toftejorg Rotary Spray Head is designed for use in pharmaceutical, biotechnological, food and dairy processing
applications. It may be used in reactors, mixing/processing tanks, spray dryers and other process equipment with a volume
from 0.1 – 50 m³ (22 - 10,998 US gallons) and storage tanks up to 125 m³ (27496 US gallons). For larger volumes, multiple
Alfa Laval Toftejorg Rotary Spray Heads may be applied.
Application assistance and optimal position recommendation is available.
For use in explosive hazard zones the ATEX/IECEx version can be used, provided it is installed according to safety instructions
in local regulations.

Functioning
The flow of the cleaning media causes the head of the Alfa Laval Toftejorg Rotary Spray Head to rotate, with fans laying
out a swirling pattern throughout the vessel. This generates a vibrating impact and cascading flow that covers all internal
surfaces of the tank or reactor. The device’s self-cleaning feature is achieved by directing the cleaning media through the
rotating bearing and onto the neck of the elongated head.
