Drainview Products QU-E2 Auto Drain

The Drainview Products QU-E2 Auto Drain is a professional-grade 110V electronic condensate removal solution designed for demanding compressed air systems. Built for durability and precision, this timed condensate drain features a 1/4" NPT connection and is engineered to handle operating pressures up to 175 PSI. The integrated solid-state timer allows for adjustable discharge intervals and duration, ensuring efficient moisture management and preventing liquid carryover in your pneumatic lines. This automatic tank drain valve is a critical component for maintaining system integrity and reducing manual maintenance cycles in commercial and industrial HVACR setups. By automating condensate management, the QU-E2 protects downstream equipment from corrosion and slugging, making it a reliable solenoid drain valve for air compressors and receivers.

Key Technical Benefits:

• Adjustable Timing Cycles: Independent settings for "on" and "off" cycles allow for precise control based on ambient humidity and system load.
• High Pressure Rating: Rated for up to 175# service, suitable for a wide range of standard compressor applications.
• Robust Solenoid Construction: The 110V coil is designed for continuous duty and high-cycle reliability in harsh mechanical rooms.
• Compact Profile: The 1/4" NPT footprint allows for easy installation in tight spaces or direct mounting to tank bungs.
• Manual Override: Includes a test button to manually cycle the valve and clear debris or verify operation during routine inspections.

Common Technical Questions:

How do I adjust the drain interval for high-humidity environments?
The QU-E2 features two potentiometers. For high-humidity areas, decrease the "off" time and slightly increase the "on" duration to ensure the bowl or tank is fully evacuated without excessive air loss.

What is the proper orientation for installing the QU-E2?
For optimal performance, install the valve in a vertical orientation with the solenoid coil facing upward. This prevents sediment from settling directly on the plunger, extending the life of the internal seals.

Can this unit be serviced if debris clogs the orifice?
Yes, the valve body and strainer (if equipped) should be inspected periodically. Always isolate the pressure and disconnect the 110V power source before disassembling the valve for cleaning.
