The Alfa Laval MultiMidget is a Rotary Spray Head that uses cleaning media for coverage and impingement. This rotary spray head is a useful alternative to conventional static spray balls, as it uses low volumes of cleaning fluid at low pressure. The double ball bearing in the head of the MultiMidget makes it suited to all industrial cleaning applications, such as tanks, reactors, vessels and other containers ranging from 0.1 m3 to 10m3 (27 – 2,700 US gallons), depending on dimensions and cleaning task.
Working principle
The flow of the cleaning media makes the MultiMidget’s head rotate, and the fan-shaped jets generate a swirling pattern throughout the tank or reactor. This ensures the impact is sufficient to effectively remove residual product, as the cascading flow reaches and covers all internal surfaces of the vessels.
The MultiMidget are designed to be installed in any given angle.
Different spray patterns can be chosen to make the head suitable for various applications and tank designs, across the dairy, brewery, distillery, beverage, food, IBC (intermediate bulk container) and personal care industries, among many others.

MultiMidget Key Features
Cost-Effective Cleaning
Rotary Spray Heads like the MultiMidget effectively clean tanks using less water, less energy and less cleaning agents than Static Spray Balls. This helps reduce consumption of high-purity water and chemicals.
Efficient Residue Removal
As the MultiMidget Spray Head rotates, its fan-shaped jets produce a swirling pattern throughout the vessel. This generates the wetting/impact needed for the efficient removal of the residual product.
Economic & Sustainable
The Alfa Laval MultiMidget minimises the consumption of water and cleaning media. Easy to customise to meet customer requirements, the MultiMidget allows companies to spend less time cleaning and more time producing.
Performance Reliability
Designed with minimal internal pressure loss, Alfa Laval Rotary Spray Heads rotate at pressures of less than 0.1 bar; however, the recommended operating pressure for the MultiMidget is 2 bar.
Low Maintenance, Minimal Downtime
Generally speaking, routine inspection is the only maintenance required for Alfa Laval Rotary Spray Head devices. These devices are so reliable that a single device in many cases can meet the requirements of a plant over its entire lifetime. The MultiMidget is lubricated by the cleaning media it dispenses.
Avoid hydraulic shock, hard and abrasive particles in the cleaning liquid, as this can cause increased wear and/or damage of internal mechanisms. In general, a filter in the supply line is recommended.
The flow of cleaning media and water causes the MultiMidget head to rotate, with the fan-shaped jets laying out a swirling pattern throughout the tank or reactor. The wetting/impact generated efficiently removes residual product, and the cascading flow ensures all of the vessel’s internal surfaces are covered.
Replacing Static Spray Balls for Increased Efficiency
One of the UK’s largest hard cheese processors increased the efficiency of its raw milk tank cleaning operations by 35% while reducing water usage by 30% with Alfa Laval Rotary Spray Heads.
Alfa Laval provide high-performance components to maximise efficiency in applications across the dairy industry, from yoghurts and cheeses to milk, cream and butter.
Alfa Laval’s range of solutions are centred around increasing output while minimising contamination and enhancing efficiency, making them ideal for applications in the personal care industry.
