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.

The need for Dry compressed air is paramount for an efficient and reliable compressed air system. OMEGA-AIR manufacturer a comprehensive range of robust & reliable refrigeration Driers.
The variants comprise of the RDP, RDL, RDF & RDHP air driers which are supplied with or without pre and after filters, automatic drains and High Pressure options (RDHP)
RDP Series <Click here for sizing table>
Refrigeration dryers RDP have been designed to effectively separate water
from the compressed air thus lower pressure dew point all the way down to +3°C.
Drying is achieved on the principle of cooling which takes place inside highly efficient
and ultra-compact 3 stage heat exchanger. In the first stage (air-air heat exchanger)
hot and humid inlet air is being pre-cooled by the cold outgoing air. In the second stage
(air-refrigerant heat exchanger) intensive water condensation takes place due to cooling the air.
All condensed water is separated from the main compressed air stream in the third
stage by the integrated demister. A proven and robust design of refrigeration dryers
enables efficient and reliable operation, fast installation and simple maintenance.

RDL Series <Click here for sizing table>
Refrigerated compressed air dryer RDL utilises a natural evolution of the RDP series.
Drying is achieved on the principle of cooling which takes place inside highly efficient
and ultra-compact 3 stage heat exchanger. This series is designed with focus on essential
components. Its compact size, optimised layout and innovative solutions reduce
manufacturing costs whilst maintaining the same levels of reliability, quality and attention
to details. RDL refrigerated compressed air dryer is designed and manufactured with respect
to the environment using recyclable materials.

Refrigeration Driers
RDF Series <Click here for sizing table>
For maximum convenience the RDF dryer series is equipped with air inlet and outlet
filters. It is based on the RDL series with extended casing to include them.
The design allows service technicians an easy element replacement. This series is
designed with focus on essential components. Its compact size, optimised layout and
innovative solutions reduce manufacturing costs whilst maintaining the same levels
of reliability, quality and attention to details. RDF dryer series is designed and manufactured
with respect to the environment using recyclable materials.
Drying is achieved on the principle of cooling which takes place inside highly efficient
and ultra-compact 3 stage heat exchanger.
