ALFA LAVAL MULTIMIDGET ROTARY SPRAY HEAD

Double Ball Bearing
It works Vertically or Horizontally

IMPLEMENTATION
Alfa Laval MultiMidget is a rotary tank washing head that uses cleaning fluid to ensure coverage and impact. Since the device uses little amounts of cleaning fluid at low pressure, it offers an alternative to conventional washing heads.   Alfa  Laval MultiMidget rotary heads have a double ball seat, which allows the washing head to operate in all directions; and it fit for use in all cleaning applications including tanks with a volume from 0,1 to 10 m3 as well as reactors and containers. Dimensions/options are available in the CAS program which is used for tank cleaning equipment of Alfa Laval.

OPERATION PRINCIPLE
The flow of the cleaning fluid rotates the Alfa Laval MultiMidget head, and fan-shaped jets create a pattern that turns like a vortex everywhere inside the tank or reactor. This creates the impact that is required to eliminate residual materials, and the gradual flow covers all internal surfaces of the tank.
