YORK Millennium®

OVERVIEW

Introducing the YORK Millennium 25, 30, & 40 ton rooftop line - units designed to provide peak performance and value both today and for years to come. When we asked our cus- tomers what they wanted in a new rooftop line, we were care- ful to listen to both the needs of today and tomorrow. So, you'll find that Millennium units not only help you solve today's problems, but can handle tomorrow's difficulties as well:

Industry Leading Efficiency - The Millennium's 9.5 EER (10 EER 25 ton) rating makes it the most frugal energy consumer in its class. When it comes to lower operating costs, Millen- nium simply outperforms the competition.

Double Wall Construction - Millennium units come double walled as standard. The galvanized sheet metal liner pro- vides the best protection against microbial growth, helping both the unit and the indoor air stay fresh and clean. And, the rigid sheet metal inner liner keeps the insulation completely out of the air stream, eliminating concerns about fiberglass particles.

Drain Pan Whisks Away Condensate - Condensate is fre- quently the source of microbial contamination. Competitive drain pans often are insufficiently sloped to properly drain all of the condensate, causing drain pan corrosion and bacterial growth to begin almost immediately. The YORK design is sloped at the 1/4” per foot recommended by the ASHRAE 62.1-2004 ventilation draft standard, with an extra large drain connection capable of removing up to three gallons of con- densate per minute. It is available in either powder coat painted steel or stainless steel for long life.

Efficient, Durable Scroll Compressors - The Millennium design uses industrial grade hermetic scroll compressors for peak efficiency and low noise operation. The compressor design is so durable that it can actually hold more liquid charge without slugging than is present in each refrigerant circuit at shipment, dramatically reducing the chances of ever slugging a compressor with liquid charge.

Multiple Refrigeration Circuits for Greater Turndown - The YORK Millennium unit has intertwined 10 ton circuits (12.5 ton circuits on the 25 ton) - giving the best unloading capabil- ity in the industry. With more and more designs requiring higher outside air quantities, the lower capacity capability is an outstanding way to neutralize outside air without over-con- ditioning the space on off-peak days. And, Millennium's high quality balance-port thermal expansion valves are more effective at metering refrigerant flow in part-load conditions, making Millennium a peak-performer across a wide capacity range.

FEATURES AND BENEFITS

When it comes to flexibility, Millennium really shines. Our cus- tomers were clear about one thing - not all installations are the same. Some have very simple needs, others are more involved. The YORK Millennium serves both markets - and all of those in between - extremely well. YORK engineers crafted a design which is both uniquely flexible and competitive, giv- ing you the best of both worlds. In addition to a competitive base product, Millennium offers unparalleled flexibility. Optional features include:

Variable Air Volume - YORK gives you the ability to vary air volume by inlet guide vanes or variable frequency drive - the choice is yours. All Millennium VAV units come standard with hot gas bypass to give extended operation range.
