FORM 201.28-EG1 (1211)IntroductionFor over 135 years, Johnson Controls has raised thebar of chiller design and customer expectations.

Continuing the history of innovationin both compressor design and Variable Speed Drive(VSD) technology, Johnson Controls proudly introducesthe YORK YVAA.In the past, the choice to use an air-cooled chiller camewith the expectation of compromise, where simplicity ofdesign and maintenance were traded for performance andHI¿FLHQF\ 7KH QHZ 9 SURYLGHV D EHWWHU EDODQFH E\ combining the best of both - a high performance designthat minimizes the total cost of ownership.YORK YVAA model air-cooled chillers provide superiorSHUIRUPDQFH LJKHU HI¿FLHQF\ KHDW H[FKDQJHUV FRXSOHG with variable speed operation and smart controls elevateWKH V\VWHP HI¿FLHQF\ WR D ZKROH QHZ OHYHO 7KH UHVXOWLQJ EHQH¿W IURP 9 FKLOOHUV LV PXFK JUHDWHU WKDQ WKH VXP of its parts.(I¿FLHQF\ 5HGXFH \RXU FRQVXPSWLRQ 9 FKLOOHUV DUH -RKQVRQ &RQWUROV¶ PRVW HI¿FLHQW DLU cooled chillers.
