Presenting the GEA TTI 150 at ACHEMA 2018 – an explosion-proof separator for chemical applications

The centrifuge 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, vapors or mists) and Zone 2 (an area in which, during normal operation, a potentially explosive atmosphere as a mixture of air and combustible gases, vapors 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 (e.g. 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 percent. The direct drive also reduces the space required for the separator by 35 percent.
