Atlas Copco LD200 Condensate Drain Valve 2202815905

Atlas Copco LD200 Electronic Condensate Drain Valve (MPN: 2202815905) – 24V, 16-Bar Zero-Loss Drain

The Atlas Copco LD200 (Part Number: 2202815905) is a level-sensing electronic condensate drain engineered to eliminate moisture from pressurized air lines without wasting valuable compressed air. Utilizing non-wearing capacitive level sensors, the unit continuously measures liquid accumulation inside an integrated collection chamber. It actuates a pilot-controlled diaphragm only when condensate reaches a critical threshold, closing immediately before compressed air can vent into the ambient atmosphere.

Designed for demanding maritime and heavy industrial compressor setups, the LD200 manages aggressive, oil-contaminated condensate as well as pure water emulsions generated across interstage coolers, refrigeration dryers, cyclone separators, and air receiver vessels. Its IP65-rated housing protects internal solid-state control logic and low-voltage electrical components from extreme marine environments, engine room salt-spray, ambient heat up to +60°C, and severe mechanical vibration.

Frequently Asked Questions

What makes the Atlas Copco LD200 superior to conventional timed solenoid drains?

Timed solenoid valves cycle open regardless of whether water is present, venting clean compressed air into the room and wasting substantial electrical energy every hour. The LD200 features capacitive level sensors that open the valve only when liquid accumulates, resulting in zero loss of valuable compressed air and lower power costs.

What causes the alarm LED to illuminate on the LD200 unit?

The alarm sequence triggers when the drain has attempted multiple discharge strokes without the liquid level dropping below the lower sensor zone within a set time envelope (typically 60 to 120 seconds). Common causes include a blocked internal strainer, an obstructed discharge line, or a downstream backpressure issue preventing ejection.

Can the Atlas Copco LD200 operate on both AC and DC 24-volt systems?

Yes. The built-in power supply electronics in MPN 2202815905 accept both 24V AC (50/60 Hz) and 24V DC systems across a nominal tolerance band of ±10%, making it directly compatible with stationary plant switchgear and shipboard battery banks.

Is it necessary to install an isolation valve before the LD200 inlet?

Yes, installing a full-port 1/2″ ball valve upstream of the condensate drain is strongly recommended. This enables routine maintenance, cleaning of the inlet mesh, or replacement of the diaphragm seal kit without needing to depressurize the entire compressed air header.

What should I do if the valve fails to drain during manual test button activation?

First, verify that the supply pressure is at least 0.2 bar (2.9 psi), as the pilot-operated diaphragm requires minimum system pressure to lift. If pressure is verified, isolate the unit, disconnect power, relieve internal pressure, and check for fine pipe scale lodged inside the pilot nozzle or around the main diaphragm seat.
