OSC condensate treatment

If the oil in compressor condensate is not removed before it enters the sewage system, it can cause significant environmental damage. Therefore, condensate treatment is not only the responsible thing to do; in most countries it’s the law. Thanks to its multistage filtration, Atlas Copco’s OSC removes oil from your compressor’s condensate with unmatched precision to achieve an oil content of 10 ppm at outlet. In addition, the OSC offers zero-hassle maintenance thanks to its easily removable filter bags and cartridges.

WSD water separators

Atlas Copco’s WSD prevents condensed water from building up in your air system. The water separator comes as standard with Atlas Copco’s aftercoolers and can also be installed at any point in your system. Made entirely of rustproof material, these cyclone-based separators remove water aerosols to protect system components such as dryers and filters. Maintenance free and without moving parts, they come with an automatic or a manual drain.

IWD electronic drains

The IWD electronic drain collects and removes liquid moisture from your air system effectively, reliably and efficiently. The zero-loss drain only releases its moisture content when it reaches a pre-set level. Leaving a minimal amount of moisture, the IWD ensures no energy can escape as the receiver empties.
Thanks to its special housing, the IWD can be used in oil-lubricated and oil-free installations.

EWD electronic drains

The EWD range of electronic drains offers safe, dependable and efficient condensate drainage. The intelligent drain function monitors condensate build-up and removes the liquid only when necessary, avoiding compressed air loss. Special EWD drains are also available for oil-contaminated condensate and with additional hard coating for oil-free and aggressive condensate.

WD automatic drains

The WD 80 drain valve provides completely automatic drainage of the water that collects at the lowest point of a compressed air system (e.g. at the bottom of a receiver or cyclone separator). Its patented design ensures minimal maintenance.

TWD timer drains

Compact, easy to install and fully automatic, the TWD is a cost-effective drain solution for compressed air filters and vessels. Pre-selecting the timing and length of each drain cycle minimizes compressed air loss.

HD and TD aftercoolers

Atlas Copco’s air and water-cooled aftercoolers provide additional moisture management in facilities
with extremely high ambient temperatures. Supplied with all necessary parts, they are compact, simple to
install and easy to disassemble for cleaning. Our HD and TD aftercoolers combine minimal pressure drop with high cooling efficiency and low energy consumption. A negligible pressure drop means no production power is lost. The compressor doesn’t generate extra demand, eliminating additional energy or maintenance costs.
