Condensate is an unavoidable result of air compression. It is a chemically aggressive fluid that mainly consists of water, but also contains oil and dirt particles.
Oil carryover is unavoidable if you have compressors that use oil in the compression chamber. The lubricant will mix with the condensation and create an oily water that must be properly handled to avoid violating environmental regulations.
Just one litre of used oil can contaminate up to one million litres of fresh water. This is the reason that environmental regulations strictly prohibit the discharge of oily wastes and chemicals, including the condensate drained from a compressed air system.
Compressed air condensate must therefore be treated in accordance with water resource legislation to achieve prescribed safety levels before it can be disposed of in the waste water system. Compressor condensate must therefore be either collected and treated by special processes or treated prior to disposal to the environment. An oil/water separator can be used here to remove the oil from the condensate. Since the condensate is approximately 95% water and 5% oil, water/oil separators have been developed to reduce or eliminate the amount of oil in the condensate.

ON-Site Gas Generators
For Nitrogen (N2) & Oxygen Gas (O2)
Nitrogen generators and Oxygen generators extract the available nitrogen/oxygen in the ambient air from the other gases by applying the Pressure Swing Adsorption (PSA) technology.
The first step in the PSA process is compressed air passing through a combination of filters and an activated carbon tower with the purpose of removing dust, entrained oil and water.
The purified air is then directed to one of two adsorption vessels that are packed with carbon molecular sieves (CMS). The remaining impurities such as carbon dioxide and residual moisture are adsorbed by the CMS at the entrance of the adsorbent bed. PSA process in oxygen generators is very similar than in nitrogen generators. Just carbon molecular sieves (CMS) are replaced with molecular sieves (MS).

NITROGEN Generators
N-GEN Nitrogen <Click here for sizing table>
The N-GEN nitrogen generators extract the available nitrogen in the ambient air
from the other gases by applying the Pressure Swing Adsorption (PSA) technology.
During the PSA process compressed, cleaned ambient air is led to a molecular
sieve bed, which allows the nitrogen to pass through as a product gas, but adsorbs
other gases. The sieve releases the adsorbed gases to the atmosphere, when the
outlet valve is closed and the bed pressure returns to ambient pressure.
Subsequently the bed will be purged with nitrogen before fresh compressed air will enter
for a new production cycle. In order to guarantee a constant product flow N-GEN nitrogen
generators use two molecular sieve beds, which alternatively switch between the
adsorption and the regeneration phase.
Industrial nitrogen gas can be also produced by separation of gaseous air using
membrane technology or fractional distillation of liquid air using cryogenic technology.
Decision on production method depend on required purity, volume and regime of consumption.
NC-GEN (compact) Nitrogen <Click here for sizing table>
Compact PSA nitrogen generators NC-GEN extract the available nitrogen in the
ambient air from the other gases by applying the Pressure Swing Adsorption (PSA)
technology.
During the PSA process compressed, cleaned ambient air is led to a molecular sieve bed,
which allows the nitrogen to pass through as a product gas, but adsorbs other gases.
The sieve releases the adsorbed gases to the atmosphere, when the outlet valve is
closed and the bed pressure returns to ambient pressure.
Subsequently the bed will be purged with nitrogen before fresh compressed air will enter
for a new production cycle. In order to guarantee a constant product flow compact PSA
nitrogen generators use two molecular sieve beds, which alternatively switch between the
adsorption and the regeneration phase.
NM-GEN (Membrane) Nitrogen <Click here for sizing table>
The membrane nitrogen generators NM-GEN extract the available nitrogen
from the compressed air. Membrane nitrogen generators use hollow fibre
membrane technology to separate nitrogen from other components in
compressed air.
The membrane uses the principle of selective permeation to produce
purity nitrogen.
Each gas has a characteristic permeation rate, which is a function of its
ability to diffuse through a membrane.
Oxygen is a fast gas and is selectively diffused through the
membrane wall, while nitrogen is allowed to travel along the inside of the fibre,
thus creating a nitrogen-rich product stream.
The oxygen-enriched gas, or permeate,
is vented from the membrane separator at atmospheric pressure.
Most of the slow gases and a very small amount of the fast gases continue to
travel through the fibre until they reach the end of the membrane separator, where
the product nitrogen gas is piped to the application

OXYGEN Generators
O-GEN Oxygen <Click here for sizing table>
The O-GEN series oxygen generators extract the available oxygen in the
ambient air from the other gases by applying the Pressure Swing Adsorption (PSA)
technology. During the PSA process compressed, cleaned ambient air is led to a
molecular sieve bed, which allows the oxygen to pass through as a product gas,
but adsorbs other gases.
The sieve releases the adsorbed gases to the atmosphere, when the outlet
valve isclosed and the bed pressure returns to ambient pressure.
Subsequently the bed will be purged with oxygen before fresh compressed air
will enter for a new production cycle. In order to guarantee a constant product flow,
O-GEN oxygen generators use modules of two molecular sieve beds, which
alternatively switch between the adsorption and the regeneration phase.
Under normal operating conditions and with correct maintenance the molecular
sieve beds will have an almost indefinite lifetime.
OC-GEN (compact) Oxygen <Click here for sizing table>
OC-GEN PSA generators have been designed for continuous separation of
oxygen from compressed air. Operation of the generator requires two columns
operated alternately. Separation takes place under pressure in the first column
while the second column regenerates with a portion of already produced
oxygen at ambient pressure.
The generator consists of upper and lower control block, controller, two columns
filled with adsorption material. Whole generator is closed in a compact stainless
steel cabinet. Springs in the columns make sure that the adsorption material will
not move during operation. Proven robust design enables efficient and reliable operation,
fast installation and simple maintenance.
