Philosophy and technical layout of process air and process
gas plants require high intelligence. They will work in challenging environmental conditions throughout the world.
Therefore, AERZEN bundles its profound know-how and
provides an excellent team, consisting of specialists from
the departments design, control system, quality and project
management with international work experience onshore
and aboard.
Thanks to AERZEN product variety, our specialists are able to
either select the appropriate machine required for your process
or to modify it if necessary, so that you always receive the optimal solution from us. As classical air compressor or important
component for special applications, such as seismic analyses
of the seabed or for the exhaust of VOC gases on oil tankers,
there are plenty of individual marine applications. This is why
the application of an AERZEN blower or compressor really makes the difference on board.

WITH AERZEN YOU CONTROL THE
SHIP.
On the basis of AERZEN compressors and blowers modern auxiliary systems for manoeuvring
and stabilising ships and keeping them free from ice can be realised. Beyond the use on yachts,
thrusters prevail also for larger ships and the air lubrication of the ship’s hull promises further
energy savings in maritime shipping business in future. Anti-Heeling systems tailored for
the ship dynamically arrange for an always smooth and stable position in the water. Another
important process air application is wastewater treatment plants for large passenger ships.
Anti-heeling and Duck Walk.
For the stabilisation of ships in the water, nowadays, bespoke product solutions made by AERZEN are used for the Antiheeling systems. Via a piping system water in the ballast water
tank of the ship is pressed from one side of the ship to the
other by means of a precisely dimensioned blower. Depending
on the present position of the ship, the unit controls via air
valves to which side of the ship the water is pressed. These can
change the air flow in less than one second.
In a calm situation at any time.
Anti-heeling-Systems with blowers are considerably more economical and energy saving than those with pumps. Floating
hotels, cargo ships, tankers or cable ships lie more steady in moving water and stay stable even during loading and unloading.
If you use the Anti-heeling unit reversed it comes to a “Duck
Walk”, a slight swaying which serves for keeping the icebreakers
free from ice. For example on the ‘Polarstern’, the currently biggest and most modern German research vessel.

This also applies for mobile plants on ships. The heart of the
plants is our Delta Blower and Delta Hybrid packaged units,
supplying the aeration tank of the aerobic sewage water
cleaning with air. Afterwards, the wastewater gets into a
settling tank where solids are separated. Then, the purified
water is sterilised before it is discharged into the waters.
Navigating by saving energy.
Modern ship concepts consider energy aspects from the start.
Air lubrication is particularly interesting for cargo ships. Oilfree compressed air, which can e.g. be generated by an AERZEN Delta Blower or Delta Hybrid, flows out of numerous nozzles under the ship’s hull and forms an air curtain between the
skin of the ship and the ambient seawater. Friction and fuel
consumption are reduced. Thrusters or rudders are operated
with oil-free compressed air. Starting from yachts, nowadays
they are also used on large ships.
Water treatment at sea.
The days when waste water of a ship was simply dumped at
sea are over. Large passenger ships and cruise ships cannot
store the wastewater volumes of thousands of passengers until they reach the next harbour. A wastewater treatment plant
with machines made by AERZEN provides remedy. We gathered experience for decades with the conception and equipment
of wastewater treatment plants of all sizes worldwide.

AT AERZEN YOUR PROCESS GASES
ARE IN GOOD HANDS.
No matter, whether combustible or not, the AERZEN experts know how to treat process gases. Our
screw compressors are used in plants for Boil-Off gas compression on LNG carriers, same as for
the recovery of Volatile Organic Compounds (VOC).
Nitrogen compression for the use as inert and flushing gas or for Blanketing is a typical application
for our Delta Blower positive displacement blowers. AERZEN compressors can be found also in
many refrigeration plants aboard
Good for the environment. Good for the costs.
When loading and unloading tankships with crude oil, volatile organic hydrocarbons (VOCs) are released into the atmosphere. They not only represent an unused energy potential
but also increase the greenhouse effect. Furthermore they
contribute to the generation of ground-level ozone and other
photochemical reaction products. By means of a VOC recovery
unit aboard, these substances can be liquefied again and fed
to the crude oil cargo. Screw compressor packages made by
AERZEN particularly developed for this process help to reduce the greenhouse effect.
VOC units with AERZEN technology are used successfully on
many tankships.
During the transport of liquid gas (LNG) on tankships, due to
the gradual warming of the cold liquid gas so-called Boil-off
gas evaporates. While, in former times, this gas was blown
off into the atmosphere, nowadays, for reasons of environmental protection it is recompressed with the help of units
made by AERZEN and led back to the process.

Our experts for special applications.
There are hardly any limits to the possible applications of
AERZEN positive displacement blowers, rotary lobe compressors and screw compressors. Mainly in the luxury segment of yacht building the long forgotten air injection to
the ship’s propeller experiences a renaissance. So, screw
noise is eliminated to the largest possible extent and cavitation is avoided. The result: smooth drive and longer service life. Air curtain systems for impact pile driving for wind
power station foundations are a similar application. A ring of
air bubbles installed around the site protects the marine life
from harmful sound influences. Furthermore, AERZEN already installed positive displacement blowers on surveying
ships and research ships for seismic survey of the sea floor.

AERZEN MOVES BULKS WITH
PRESSURISED AIR AND VACUUM.
Pneumatics plays an important role in loading and unloading bulk materials. AERZEN blowers and
compressors generate overpressure and vacuum for this purpose. Even big individual loads can
be lifted easily thanks to pressurised air, e. g. with semi-submersible heavy lift ships. If higher
pressures are required, as for example for pressurised air, AERZEN blowers and compressors
provide the accurate elevated intake pressure.
Pneumatic conveying of bulk materials.
Whether vacuum conveying or positive pressure conveying is
used depends on the conveying material and the deployment
scenario. AERZEN has long-term experience with both procedures and already supplied pneumatic systems for ships, port
facilities and factories. The largest machines are installed in
lifting systems and unload transport ships with an hourly capacity of up to 1,000 tons. Mobile unloading vehicles ( e.g.
silo trucks), which are driven to the individual locations in the
harbour, are equipped with AERZEN products. AERZEN oilfree compressing positive displacement blowers, rotary lobe
compressors and screw compressors are the solution for all
these transportation tasks providing highest efficiency and
reliability.
12
Economical compressed air generation.
Semi-submersible ships are used for lifting ships out of the
water, working on the hull or to salvage a non-seaworthy
vessel. The hoisting of the hull is carried out by feeding compressed air into the ballast tanks. Water is pressed out of the
tank. Due to this generated lift the hull is hoisted.
If compressed air with higher pressures is needed, a compressor stage of the downstream piston compressor can be omitted thanks to a compressor supercharging by AERZEN Delta
Blower or AERZEN Delta Screw. Thus, the investment costs for
the entire plant are decreased significantly.
All fields of application covered.
AERZEN is one of the three world-wide leading application

AERZEN. Compressor technology as a principle for success.
Aerzener Maschinenfabrik was established in 1864. In 1868
we built Europe’s first positive displacement blower. In 1911 we
­introduced the first turbo blowers, in 1943 the first screw-type
compressors and in 2010 the first rotary lobe compressor units
in the world. Innovations made by AERZEN continue to drive
the development of compressor technology. Today AERZEN
is one of the world’s major long-established manufacturers of
positive displacement blowers, rotary lobe compressors, ­rotary
piston gas meters, screw compressors and turbo blowers. And
in many areas of application an undisputed market leader.
