Explosion-proof separator for chemical applications

The safety of persons, materials, production and delivery processes, and the protection of the environment – are top priorities.

GEA’s new TTI 150 separator is designed for the special requirements of combustible materials.



The TTI 150 separator, like all GEA’s explosion-proof separators and decanters, is equipped with certified electrical equipment and a high-vibration safety locking mechanism.

It is designed for operation in Zone 1 (an area in which, during normal operation, a potentially explosive atmosphere may occasionally form as a mixture of air and flammable gases, vapours or mists) and Zone 2 (an area in which, during normal operation, a potentially explosive atmosphere as a mixture of air and combustible gases, vapours or mists normally does not occur or only for a short time) environments.

GEA offers single and complete skid versions for all common international standards, guidelines and certifications (ATEX, IEC-Ex, NEC) in different sizes.

This gas-tight TTI 150 separator meets the criteria of the European ATEX standard. The oxygen atmosphere is replaced by inert gas. A positive pressure during operation ensures permanent inert gas coverage.

With this special design, even liquids with large differences in density can be centrifugally separated efficiently.

The machine is designed with special materials to meet corrosion-related specifications.

The load-bearing bowl parts of the TTI 150 separator are made of high-alloy stainless steels and can also be manufactured with a cladding of even higher-quality material (eg, Hastelloy) if necessary.

The separator is equipped with an integrated GEA directdrive which offers exceptional energy advantages: The bowl is driven directly by an integrated, frequency-controlled three-phase motor and is infinitely variable.

Thanks to its greater efficiency, this drive ensures significant energy savings of up to 30%. The direct drive also reduces the space required for the separator by 35%.

Maintenance-friendly drive

The drive concept is very easy to maintain. A drive coupling is not necessary due to the integrated GEA directdrive.

The need for spare parts is lower than for standard separators. This means that significantly less time is required for maintenance.

Because the design uses a very robust and safe asynchronous motor to achieve maximum machine reliability, standard frequency inverters can be used.

Integrated freeze-drying

GEA offers a complete programme of high quality products associated with all aspects of aseptic manufacturing and integrated solutions, in addition to efficient service for the pharmaceutical, healthcare and biotech industries.

For example, its LYOSPARK controlled nucleation technology facilitates uniform ice crystal formation in laboratory and production-scale freeze dryers with a minimum degree of supercooling.

Producing more consistent and larger ice crystal sizes with a more open product structure, faster drying and reconstitution times can be achieved.

LYOSPARK also ensures inter-batch homogeneity, improves process repeatability and enhances both the presentation and quality of the final product.

For online moisture control, the LYOSENSE sensor uses multipoint NIR measurements to comprehensively and non-destructively evaluate freeze dried product cakes in real-time.

This easy-to-install and use measuring device provides the following benefits: whole cake assessment; fast processing times (5ms); and a simple operator interface.

And, whether it’s a fad or the future, 100% vial traceability is becoming an increasingly important consideration in the pharmaceutical freeze-drying industry.

LYODATA provides unique marking, clear identification and the consistent traceability of pharmaceutical primary packaging, making drug counterfeiting practically impossible.

The system also offers continuous quality inspection, 100% line clearance and precise sampling.
