Advanced Automation & Control Systems


The tank is prepared for seamless integration into automated process control architectures typical of modern beverage production lines. Instrumentation ports and valve interfaces support level, pressure, and temperature monitoring, as well as aseptic steam-in-place (SIP) and clean-in-place (CIP) routines. The system documentation set includes activation and sequence diagrams and a communication description for S7-based control, supporting PLC/HMI connectivity, interlocks, and recipe-driven operation.




PLC-ready signals for level, pressure/vacuum, and temperature


Interfaces for aseptic valve clusters and CIP/SIP circuits


Safety interlocks for pressure and vacuum protection


Documentation for commissioning and parameterization




Production Line Integration Capabilities


Designed to function as an aseptic buffer or storage tank between thermal processing (e.g., UHT) and downstream filling. It can operate standalone or inline within a complete packaging line and is suitable for beverage production environments handling PET, glass, or carton filling operations. Format changes are minimal since storage capacity and process parameters are recipe-controlled.




Inline integration with UHT, aseptic valve manifolds, and fillers


Standalone operation for batch buffering and sterile hold


Compatible with CIP/SIP plant utilities and sanitary piping


Ideal for modernization of a second hand or used bottling line




Machine Condition & Maintenance History


The pressure vessel (tank body) is newly manufactured in 2025, paired with system documentation and aseptic process lineage originating from a 2011 Tetra Pak aseptic system. The unit is offered as second hand equipment and is ready for operation upon proper installation and commissioning. Availability of technical manuals supports maintenance planning, preventive routines, and efficient start-up.




Body is new (2025) with documented pressure test and design ratings


Provided with technical manuals, preventive maintenance references, and flow/layout documents


Prepared for swift recommissioning in industrial packaging facilities




Operational Performance & Versatility


Engineered for hygienic and aseptic conditions, the tank provides stable pressure/vacuum capability for sterile storage.
