Features

State-of-the-art automation

State-of-the-art automation

Ensures the highest safety standards

Enhanced process integration with advanced monitoring, control and PLC communication provides top-quality automation and ensures the highest safety standards.

Smart pulsing control

Smart pulsing control

Low operating costs and emissions

The system is optimised for low operating costs and emissions using a design that pulses as much as necessary, but as little as possible. An integrated controller uses flow resistance to automatically adjust required speed (interval) and cleaning intensity (compressed air pressure).

Improved powder recovery

Improved powder recovery

Extend bag lifetime

A baffle plate in the filter provides a low and even velocity profile. This arrangement prolongs filter bag lifetime substantially compared to models with a tangential air inlet.

Computational fluid dynamics (CFD) modelling

Computational fluid dynamics (CFD) modelling

Optimised geometry, layout and flow velocities

Air flow capacities of 26,000–287,000 m3/h are optimised by using computational fluid dynamics (CFD) modelling to fine-tune layout and flow velocities.

Options

Process adaptive pulsing control

Process adaptive pulsing control

Lower compressed air consumption

An adaptive pulsing control system pulse as much air as necessary, but as little as possible. This decreases compressed air consumption, prolongs bag lifetime and reduces CO2 emissions. The self-adjusting system is housed in an integrated cabinet and accessed via the main PLC or remotely.

Multiple inlets

Multiple inlets

Reduced building footprint

A bag filter with spray dryer and twin cyclone can be fitted with multiple air inlets that remove the need for a trouser piece. This reduces building footprint by around 20 percent compared to a single air inlet – an advantage in compact plant environments.

A sustainable choice

With its low consumption of both energy and compressed air, Tetra Pak Bag Filter is an environmental-friendly choice. The flow patterns and filter media provide enhanced filtration – in short, the bag filter is ready to the emission standards of the future.

Hygiene and cleanability

No rotating parts, no rubbing, no bolts and nuts that fall into the product – Tetra Pak Bag Filter is built for uncompromising hygiene. And as it’s fully CIPable, cleaning is efficient too. There are no ‘spray shadows’, and the CIP nozzles reduce risk of bio-contamination.

Optimising performance

Tetra Pak Bag Filter is a perfect example of state-of-the-art engineering and automation. Process adaptive pulsing control makes sure the air shots that punch the powder away happen when they are needed. Optimised geometry is achieved through advanced layout, fine-tuned flow velocities and CFD modelling. And the clever design – large distance between bags, locked cages to stop bags from swinging – extends bag life time.
