The EWD 330 is an electronic / automatic drain valve designed for condensate removal in compressed air systems. It operates on a level‑sensing principle so that condensate is drained only when necessary, making it a zero-loss drainage solution (i.e. minimal compressed air is wasted). It is suitable for use in compressor receivers, aftercoolers, dryers, drip legs, etc. The unit is built for dependability, with a wide drain path to minimize clogging, and designed for industrial compressor systems up to high capacities.
Key Features & Benefits
- Zero‑loss drainage: valve only opens when liquid level reaches threshold, avoiding unnecessary air loss.
- Wide drain channel to reduce chances of clogging.
- Level sensor that can trigger alarms / fault detection.
- Compatible with oil‑contaminated condensate (for lubricated compressors) as well as options / coatings for more aggressive condensate.
- Adjustable drain timing / cycle parameters (on / off durations).
- Robust construction: brass / forged body, durable materials, ingress protection (IP rating) on electronics.
