Through the suction nozzle,
the contaminated gas is
drawn in and is entrained
by the scrubbing liquid.

Make distilled water from
wastewater using low-grade heat
EcoStill (photo) is based on patented
multistage humidification/dehumidification
(MHD) technology - a distillation
process operating under atmospheric
pressure, below boiling point
with evaporation and condensation in
air streams, without pressure or vacuum.
With only one moving component,
EcoStill works with low-grade
heat (temperature less than 80°C) as
hot water, low-pressure steam or exhaust
gas. It produces distilled water
that can be reused or safely discharged
into the environment. Each
EcoStill module can treat up to 300
m3/yr of liquid waste and recover up
to 90% of the water. Up to five modules
can be assembled in parallel for
treatment capacities of up to 1,500
m3/yr. Hall 5.1, Stand D52 - TMW,

Cold is okay for this
chemically resistant elastomer
The Perplast ICE G75LT offers a
combination of " excellent " chemical
resistance and low-temperature performance.
This perfluoroelastomer
material has been specifically developed
to perform under extreme conditions,
in temperatures as low as -40°C
or lower. The elastomer has been formulated
to provide increased resistance
to a broad range of chemicals
by carefully controlling the molecular
architecture. Also, this material has
low permeability and as a result, it
is less prone to swelling, leading to
extended in-service performance in
valves, pumps and mechanical seals.

Filterbelts featuring
double-layer weaving
This company has pioneered the double-layer
weave (DLW) filter media
made of synthetic yarn technology, and
now offers the widest range of doublelayer
filter media in the market. The
Tetex DLW filter media family ranges
from a standard polyester fabric to
polyether ether ketone (PEEK). The
latest innovation is the heavy-duty
line, Tetex DLW HD, a next generation
filter media for vacuum belt filters.
Choice of pore sizes from 7 to 150 µm,
in widths up to 3.5 m (6 m on request)
are available. The company also is
presenting its Pharma-Grade dust filter
bags for particle recovery to meet
the demanding conditions imposed
by regulations in the pharmaceutical
industry. Hall 5.0, Stand D60 - Sefar

This steam trap has
no moving parts
The recently launched Delta DSV energy
saving steam trap has no moving
parts and yet is still able to completely
remove condensate while holding the
steam back in the system, even in
varying load or pressure conditions.
The Delta DSV is guaranteed for ten
years and can never fail open and pass
steam. The steam trap is said to save
between 10 and 20% of a boiler fuel
bill through the elimination of any
steam wastage, while allowing better
heat transfer in the steam system
through its condensate-removal ability.
A full range of sizes is available -
from DN15 threaded through DN200
flanged - covering pressure ranges
up to 100 bars saturated steam. Hall

In the separator,
the purified gas
and the
scrubbing liquid
are separated.
by intensive
contact with
the scrubbing
liquid.
Gas Cleaning
and Cooling
with jet and Venturi scrubbers.
All scrubbers are individually
designed to achieve maximal
purity and efciency. The gas
ow ranges between 0.05 m³/h
and 100,000 m³/h at temperatures
up to 1,300 °C. Our gas
scrubbers are particularly suited
for explosive gas mixtures, highly
corrosive and dust-loaded gases.
