Your Solution For Energy and Cost Savings McQuay Packaged Chiller Plant
Innovative Solutions for Your Chiller Plant McQuay packaged chiller plants provide energy efficient chillers integrated with pumps, controls, electrical switchgear, wiring, and piping. All of these packaged components are factory assembled on a rugged structural steel base for indoor or outdoor mounting and connection to site power and piping. McQuay packaged chiller plants offer a flexible and energy efficient alternative to site-built equipment rooms. Benefits for the Bottom Line Packaged chiller plants are a value-added solution to the high costs of constructing mechanical rooms in both new construction and renovation projects. Typical applications include: district cooling plants performance contracting and energy services new construction renovation or expansion Packaged chiller plants can provide benefits that impact the bottom line of a project. lower construction costs shortened construction cycle quicker building occupancy additional chiller capacity without enlarging the existing mechanical room cost-effective solution to replacing existing chillers portability of the packaged chiller plant flexible ownership options The GeneSys air-cooled screw chiller continues the McQuay legacy of high quality, high efficiency, and quiet operation. McQuay Distinction Series WDC Dual Compressor centrifugal chillers lead the industry in part load efficiency.
Flexible, Reliable Components The Added Value of McQuay Chillers McQuay packaged chiller plants are available with a variety of chillers including water-cooled centrifugal, air-cooled screw, and air-cooled scroll models. The McQuay Distinction Series centrifugal chillers deliver unmatched part load efficiency, a small footprint for more usable space, and environmentally friendly HFC-134a refrigerant. With numerous compressor, motor, evaporator, and condenser combinations, McQuay centrifugal chillers can be built to your specific design conditions. Air-cooled chillers in 10 to 475-ton sizes can also be utilized. Both the screw and scroll chillers offer quiet, reliable operation, and energy efficient performance that meets or exceeds ASHRAE Standard 90.1-1999. McQuay packaged chiller plants include the following components: High efficiency chillers Chilled water pumps and/or condenser water pumps Electrical switchgear for chiller, pumps, remote cooling tower, basin heaters, internal heating and ventilating system, and lighting Integrated MicroTech II controls offer Protocol Selectability using open, standard protocols such as LonTalk or BACnet. Heavy duty equipment mounting base Interconnecting piping, valves, and wiring Expansion tank, vents, drains, and relief valve piping Penthouse units for outdoor applications are weather-resistant and insulated Both indoor and outdoor units can be equipped with their own heating, ventilation, and lighting McQuay packaged chiller plants are factory designed, built, and tested for reliability. Interconnecting piping is provided between components.

McQuay Packaged Chiller Plant Benefits Lower First Cost The first cost of a McQuay Packaged Chiller Plant can be as much as 40% less than buying the equipment and rigging, setting, piping, and wiring a site-built chiller plant. Operating Cost Savings McQuay chillers inside the packaged chiller plant provide superior part load efficiency. Open Protocol DDC Controls McQuay MicroTech II controls use LonTalk or BACnet protocol for easy integration with your preferred building management system or a remote monitoring software package. Advanced multiple machine controls can optimize chiller plant efficiency for significant energy savings. Factory Designed and Built Factory designed and assembled system with an extensive, consistent quality control process ISO 9002 certified. Reliability advantage compared to on-site fabricated chiller plants. Shorter Construction Time Packaged chiller plant can eliminate equipment room construction time. Fast track capabilities for time-critical installations. Quicker building occupancy. Improved System Reliability Factory run tests: chiller piping is pressure tested, the electrical system is dry run, and the control interlocks are verified. The packaged chiller plant arrives at the job site ready for connection to the chiller water system, cooling tower, and electrical power. ASHRAE Standard 15 Compliance Outdoor penthouse units are designed and built for compliance with ASHRAE Standard 15-1994, Safety Code for Mechanical Refrigeration. The packaged chiller plant can be shipped fully enclosed (background) or on a structural skid for indoor use (foreground).
