Adiabatic humidifier
Carel’s humiFog direct is an adiabatic
humidifier for direct in-room applications,
featuring easy installation, low energy
consumption and a simple and intuitive
user interface thanks to the latest-
generation touch display.
Ideal for industrial processes involving
hygroscopic materials, humiFog direct
guarantees the right level of relative humidity,
preserves product quality, helps reduce
waste and improves business continuity.
Atomising pure water into very fine
droplets that evaporate spontaneously
in the air ensures the right level of relative
humidity with low energy consumption.

Adiabatic humidification is the ideal
solution, as it has the dual advantage of
controlling air humidity and countering the
thermal load generated by machinery.
One application example is the printing
and paper industry: properly managing
relative humidity in printing processes avoids
the build-up of electrostatic discharges
and misalignments due to variations in
dimensions, and optimises ink absorption.
In winter, as the heat generated by the
manufacturing processes and heating
systems dries the air, the moisture content in
the paper falls dramatically, consequently
affecting its properties. Correct relative
humidity control increases productivity
and efficiency, minimising costs due to
downtime and wasted material.

Efficient and robust
GEA presents the HG66e,
a new semi-hermetic
compressor. The HG66e is a
completely new six-cylinder
series for large capacities
with high efficiency in the
fields of air conditioning
and refrigeration. With the
HG66e series, four sizes
cover the range from 116.5
to 180.0m 3 /h displacement
(at 50Hz).
The new HG66e series
combines state-of-the-art
technology with GEA’s
design standards. The
new compressors are
equipped with the in-
house and further developed
mexxFlow 2.0 valve plate system.
All compressors use the proven,
direction-independent oil pump
lubrication system, which enables
a wide speed control range
in operation with frequency
converters. The reliable and
safe oil supply is guaranteed
by the single-circuit lubrication
system. The resulting low oil throw
increases the efficiency of the

entire refrigeration system. The easily
removable oil strainer facilitates
maintenance.
In addition to efficiency and
robustness, one of the focal points in
the development of the new HG66e
compressors is ease of servicing.
Thanks to the sliding seat, the stators
can still be changed on site without
special tools.
