WSD 25-750 / WD 80 / EWD 50-1500: Water separators and drains
2Pages

A range of effective after-coolers and water separators to match your compressor 4 4 Atlas Copco offers a range of after-coolers and water separators, which combines minimal air pressure drop with high cooling efficiency and low energy consumption. After-coolers are supplied complete with all necessary parts. They are compact, simple to install and easy to dismantle for cleaning. The negligible pressure drop effected by the after-coolers means virtually no loss of power to compressed air-driven tools, machines and pneumatic devices. Thus no extra demand is placed on the compressor and no additional energy or maintenance costs are incurred. Water-cooled HD after-coolers Atlas Copco HD water-cooled after-coolers are designed to combine a high level of cooling with economic water consumption. The air leaving the compressor is cooled in a bundle of stainless steel tubes, with the cooling water and the compressed air flowing in opposite directions. A water separator is provided with the cooler as standard. The cooling tubes are reeled inside to create turbulence for more rapid cooling of the compressed air. To increase the cooling effect, the water is deflected by baffles. Efficient water separators, automatic and intelligent drainage 4 EWD electronic condensate drains WSD water separators 4 The water separators provided by Atlas Copco have ample capacity. Reliable automatic drain devices prevent condensed water from building up in the coolers. The water separators are delivered as standard with the after-coolers. They can also be installed in any point of your air net. Type Capacity range Maximum working pressure Made entirely of totally rustproof material, these general purpose separators feature very efficient separation by cyclone. Maintenance-free with no moving parts, they have an automatic and manual drain.

The intelligent drain function monitors condensate build-up with liquid level sensors and and evacuates the condensate only when necessary, thus avoiding wastage of compressed air and giving considerable energy savings. Weight Width The exact net pressure The EWD drain device offers security and confidence, enabling you to solve all condensate discharge problems even with heavily contaminated systems. A wide range of different EWD drains is available for oil contaminated condensate and also may be provided with additional hard coating for use with oil-free and aggressive condensate. 4 4 4 4 Atlas Copco after-coolers, whether cooled by air or water, are reliable, require minimum maintenance and provide trouble-free protection against the costly effects of water in your system. Both types of after-cooler deliver air into the air-net at a temperature suitable for most types of air dryers. Air-cooled TD after-coolers Atlas Copco TD air-cooled after-coolers have an aluminium block cooling element. An electrically driven fan, shielded by a protector for user safety, forces cooling air between the fins. High cooling efficiency is combined with low energy consumption. WD automatic condensate drains The WD 80 drain valve provides completely automatic drainage of the condensate which collects at the bottom of the air receiver. The patented Atlas Copco design eliminates troublesome mechanical linkages. The automatic drain can be installed at the lowest point of a compressed air-net, (e.g. at the bottom of a receiver or cyclone separator etc.). Maintenance is minimal. The after-cooler is mounted on a sturdy frame. A water separator is delivered as standard with the TD25-650 coolers. The TD 08, is delivered with wall mounting brackets and incorporates a drain collector with manual drain.
