RELIABLE SCROLL COMPRESSOR TECHNOLOGY
Reliable, ef
Þ
cient, trou ble-free operation is the true
mea sure of a packaged rooftop’s val ue. That’s why
YORK eco
2
Packaged Rooftop Air Conditioners use
es tab lished scroll-com pres sor technology to de liv er
de pend able, eco nom i cal performance in a wide range
of ap pli ca tions. With the eco
2
Packaged Rooftop, you
get the latest gen er a tion of compressor en hance ments
added to the scroll’s inherent strengths. The sim plic i ty
of a hermetic scroll compressor allows the use of fewer
moving parts to minimize breakdown. The result: a
maintenance-free compressor providing minimum wear
and maximum runtime.
A scroll compressor op er ates with two scroll mem bers—
a
Þ
xed scroll and an identical orbiting scroll turned 180
de grees, like two hands curled and in ter locked to geth er.
As the or bit ing scroll oscillates against the
Þ
xed scroll,
it traps and compresses suction gas inside in vo lute
pock ets. As the orbiting scroll moves, the gas is com-
pressed into the central area, where it is discharged as
com pressed gas. High ef
Þ
cien cy is achieved through
a pre cise ly con trolled orbit and the use of advanced
scroll ge om e try. There is no wast ed motion. All ro tat ing
parts are stat i cal ly and dynamically balanced to ensure
op ti mal per for mance over the long haul.
Balanced components and precision machining also
ensure that smooth com pres sion occurs in all involute
pockets si mul ta neous ly. When com pres sion forces are
equally distributed over the en tire scroll surface, equal
forces in opposing directions cancel one another, min-
i miz ing any imbalance. Con se quent ly, compression is
smooth, continuous, and quiet. Vibration isolators on
each compressor handle normal vibration. For extra
qui et operation, acoustic sound blankets for each com-
pres sor are available as options.

Access doors –
full-sized access doors provide
easy access into the unit for routine maintenance
and inspection.

–
over sized ser vice valves to provide isolation
and quick rec la ma tion and charging of system re-
frigerant are avail able to minimize down time and
simplify the ser vice and re pair task.

INSTALL WITH EASE AND SAFETY
•
Factory run-tested –
Each unit is subjected to a
series of quality assurance checks as well as an au-
to mat ed quality control process before being run-
test ed. Fans and drives are balanced at the fac to ry
during test ing. The factory run-test ensures safe,
proper op er a tion when the unit is installed, and
re duc es in stal la tion and commissioning time.
