Approximately one out of every sixth beer produced worldwide has been processed in a tank equipped with one of Alfa Laval’s specially designed top plate assemblies. . A top plate assembly is a machined solid-stainless-steel plate outfitted with practically all the necessary tank safety equipment for mounting on the top of a pressurized beer tank.

The equipment on the top plate assembly provides the following functions:

  • Compensation with gas for the change in liquid volume during filling and emptying (allowing the change in liquid volume by gas filling or escape)
  • Control of the tank top pressure
  • Protection against uncontrolled overpressure or vacuum
  • Cleaning of the tank and associated equipment



Centralised placing of the tank top plate assembly secures:

  • Better tank insulation at lower costs
  • Easy installation at low costs
  • Easy access and low maintenance cost
  • All parts are cleaned during CIP

 The compact top plate design and the use of dead weight valves secure operational reliability at a competitive price.


  • Cost-effective and sanitary design
  • Straightforward installation
  • Simple and safe operation
  • Easy maintenance
  • Cleaning-In-Place of all parts
  • Possibility to combine with rotary mixers and agitators
