AccuDrain Automatic Condensate Drain

Electric Operated Condensate Drain

The Accu Drain is the industries best condensate drain. This fully automatic drain features zero air loss, saving energy for a fast return on investment. The drain is designed to close before any air-loss can occur, therefore, the condensation can be “pumped” to an elevated location. No air-loss also eliminates the noise associated with timer drains that stay open too long.

The Accu-Drain’s design makes the condensate drain ideal for systems that have oil recovery devices. These oil recovery devices (Oil/Water Condensate Separators) operate at peak performance when the incoming condensation is not agitated by a blast of compressed air that often occurs with the use of timed solenoid drains. The Accu-Drain uses a unique, straight through flow, non-clogging solenoid valve that was designed exclusively for draining compressed air systems. This eliminates the frequent failure of diaphragm valves that easily clog with small amounts of particulate.

How It Works

Condensate enters the drain through one of two inlet connections. As condensate is collected and the translucent reservoir fills, a stainless steel level switch rises. When the condensate reaches a design level, the level switch sends a signal to the straight flow posi valve, which in turn opens a full-port drain.

When installed, a light indicates power is being supplied to the drain. A second light indicates when the valve has been actuated by the float switch. An override switch is provided for manual operation of the drain.
