GENERAL

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. Millennium units are manu-
factured at an ISO 9001 registered facility, and each rooftop
is completely computer-run tested prior to shipment.
The Millennium is designed to be flexible enough to meet
your needs today and in the future. The true value of YORK's
Millennium is that it can be designed to fit any need, from
cooling only, constant volume applications to variable air vol-
ume systems with variable frequency drive.
