Overview
The McQuay Modular Central Plant combines a chiller, cooling tower, pumps and piping in a pre-engineered, pre-assembled package. This innovative system is the ideal alternative to site-built central plants when space or construction schedules are critical issues.

Reduced Owner and Contractor Risk
Single source OEM supplier and complete system performance standards. Reduces trade coordination costs and site assembly time.

Lower Installed Cost
Lower costs per ton compared to traditional “site-built” plants.

High Quality
Pre-engineered, factory fabrication and assembly provide quality that exceeds outside field practices. Galvanized finish on all structural steel and condenser water piping is standard.

Improved Efficiency
Design costs less than a comparable built-up system, while providing energy efficiency expected in more expensive systems. Comes standard with cooling tower VFDs for enhanced part load performance.

Expandable
Easily expandable design with no expensive down time. Standard connections for a rental chiller allow emergency backup capability.

Simplified Installation
Pre-engineered and pre-assembled in a wide selection of sizes from 75 to 750 tons in a single compact package with unique modular design that allows central plants up to 3,750 tons.

Green Refrigerant
McQuay chillers use HFC-134a refrigerant with no ozone depletion potential and no phase-out schedule. Chiller performance can contribute to LEED® points.

Ideal for fast-track projects
Modular Central Plants are used in a wide variety of building types, demonstrating the fast-track, simplified installation that avoids costly or unacceptable down-time.
