Condensate management

Our IWD, EWD, WD and TWD solve all compressed air condensate discharge problems, even with heavily contaminated systems. The water separators and drains offer safe, dependable and economical condensate management.

Water drains, EWD range - electronic water drains

Minimal maintenance, high reliability

With no moving parts, the water separators offer high reliability while requiring minimal maintenance. Both automatic and manual drain options are available

Energy savings

The intelligent drain function monitors condensate build-up with liquid level sensors. It evacuates the condensate only when necessary to avoid wasting compressed air and to generate considerable energy savings

Choose from a wide range

A wide range of EWD drains is available for oil-contaminated condensate. This includes models with an additional hard coating for use with oil-free and aggressive condensate

Reliable and clean air

The air that leaves a compressor reaches 100% humidity. It also contains oil (unless you are using an oil-free compressor) and solid particles. Together, they form an abrasive, often acidic, oily sludge. Without air treatment, this murky mix will enter your compressed air system, corroding pipe work, damaging pneumatic tools and potentially compromising final products.

WSD Water separators

Our WSD water separators increase the lifespan and reliability of your compressed air cooler through efficient condensate management. The water separator prevents condensed water from building up in your air system. The 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.

Atlas Copco offers a wide range of drains, extending our premium quality throughout your compressed air.

The remaining humidity in compressed air turns into water as the air cools while it moves through the system. Because water causes corrosion and damage, drains must be installed throughout your network. Atlas Copco has a range of drains; automatic, electronic or timer drains, that will keep your aftercooler, dryer, air receiver, and other equipment working optimally.

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.

Check out the IWD’s technical specifications and dimensions here.

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. The range can be delivered 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.

Explore this drain in the technical specifications and dimensions.

TWD timer drain

The TWD timer drain removes condensate using a solenoid valve in combination with an electronic timer. Pre-selecting the timing and length of each drain cycle minimizes compressed air loss. Compact, easy to install and fully automatic, the TWD is a cost effective drain solution for compressed air filters and vessels.
