Quincy QGV 20-200 HP Variable Speed Screw Compressor Brochure

Product catalog summary

Overview: The Quincy QGV Series Rotary Screw Air Compressors are designed for high efficiency and reliability, offering a range of 20 to 200 HP. These compressors are engineered to provide precise air delivery from 100% to 15% capacity, ensuring constant pressure and energy efficiency.

Key Features:

Efficiency: The QGV series maximizes efficiency with a turndown capability from 100% to 15% of capacity, maintaining stable pressure and reducing energy consumption.
Pressure Stability: The downstream pressure signal feature provides stable pressure by allowing immediate reaction to pressure changes, minimizing energy waste.
Low Demand Mode: This mode prevents the compressor from running unloaded during low demand periods, saving energy and maintaining system pressure.
Advanced Networking: Standard advanced networking capabilities allow for automatic sequencing and remote monitoring through the optional Web$ync II package.
Microprocessor Controller: A 6-inch color touch screen controller provides continuous monitoring and displays performance metrics, including system pressure and efficiency.
Warranty: Quincy offers a 10-year airend warranty and a 5-year warranty on major components, ensuring long-term reliability.

Technical Specifications: The compressors offer varying capacities at different pressures, with sound levels ranging from 68 to 78 dBA. They are designed for a maximum ambient temperature of 104° - 110°F and include features like a direct drive airend and variable frequency drive assembly.

Case Study: A bottling and packaging facility reduced operating costs by over $44,000 annually and eliminated production shutdowns by implementing the Quincy QGV-150. The system upgrade allowed for precise control of system pressure, reducing the need for inefficient compressors and lowering system pressure by 15 psi.

Conclusion: The Quincy QGV Series compressors are engineered to deliver the lowest total cost of ownership with features that enhance efficiency, reliability, and performance. They are suitable for various industrial applications, offering significant energy savings and operational improvements.
