Toftejorg MultiMidget Rotary Spray Head

Low Flow Saves on Water and Chemicals
Toftejorg MultiMidget Rotary Spray Head


The Toftejorg MultiMidget is a rotary spray head that uses cleaning media to provide coverage and impact. The device represents an effective alternative to traditional static spray balls because it uses low volumes of cleaning fluid at low pressure. The double ball bearing in the Toftejorg MultiMidget’s rotating head makes the device suitable for all industrial cleaning applications, including tanks, reactors, vessels and other containers ranging from 0.1 m3 to 10m3 (27 - 2,700 US gallons), depending on dimensions and cleaning task.

Sizing/selection and installation drawing are available in Alfa Laval CAS tool for Tank cleaning equipment.

Working principle

The flow of the cleaning media causes the head of the Toftejorg MultiMidget to rotate, and the fan-shaped jets lay out a swirling pattern throughout the tank or reactor. This generates the impact needed for the efficient removal of residual product; the cascading flow covers all internal surfaces of the vessel.

The MultiMidget are designed to be installed in any given angle
