Heat-recovery and exhaust air
pollution control at Getzner AG in Bludenz, Austria
Vorarlberg is the Western most province of Austria, bordering
Switzerland and Germany. With the impressive alpine scenery, it
is not surprising that many tourists come here for hiking or
skiing. Although Vorarlberg is a famous tourist destination, yet
only about 6% of the gross social product is generated by
The textile industry, probably the strongest branch of
industry in the last two centuries, has lost its supremacy.
However, it is still prominently represented as one of the 20
largest industrial companies in Vorarlberg belongs to the
textile industry – Getzner AG in Bludenz, founded 200 years ago,
is today the leading company for the production of African
damask fabrics and one of the leading manufacturers of shirt

In the new production halls at Getzner AG's main plant in
Bludenz, fabrics are woven and finished for ready-made garments.
The fabrics are finished in special processes mainly on new
BRÜCKNER stenters. As substances evaporate from the fabric
during the textile finishing processes, the stenters have to be
vacuumed off and therefore, exhaust air has to be cleaned before
being emitted into the environment.
The exhaust air treatment on the new stenters of Getzner AG
is carried out by a multi-stage BRÜCKNER ECO-HEAT and ECO-AIR
system. In the first ECO-HEAT heat-recovery system, heated fresh
air is generated for the drying process, which noticeably
reduces energy consumption. In the second ECO-HEAT heat-recovery
system, water is heated for the company’s internal heating
system and thus, depending on the heating requirement, up to 85%
of the invested heat energy is recovered in this process. The
pollutants from the exhaust air are condensed and separated in
the subsequent ECO-AIR exhaust air scrubber. A silencer behind
the exhaust air fan reduces the exhaust noise.

The proven ECO-HEAT components guarantee high heat transfer
efficiency and a particularly robust and maintenance-friendly
Since the heat exchangers have to be cleaned at regular
intervals from unavoidable deposits in order to maintain full
performance, they are easy to remove. The heat exchangers are
boiled regularly in the cleaning bath supplied. As Getzner AG
has replacement heat exchanger modules in stock, the heat
exchangers are cleaned without any time pressure.
With this modern multi-stage exhaust air system Getzner AG
achieves a high energy efficiency, because most of the exhaust
air heat is recovered in BRÜCKNER ECO-HEAT systems.
Last, but not the least, the picturesque environment is not
polluted by smoke, noise and odours from the production process,
thanks to the BRÜCKNER ECO-AIR exhaust air cleaning system.
